Description

The syrup purification system

The right that No. 60/403,594, this international Patent Cooperation Treaty (PCT) patent application requirement U.S. Provisional Patent Application, this application is hereby incorporated by.

Technical field

The present invention relates to contain the system of processing that the sucrose syrup is made sugar and other products with what a kind of plant materials by for example sugarcane, sugar beet or sweet sorghum and so on obtained.The invention still further relates to and be used to make equipment that contains the sucrose syrup and the method that solute content reduces.The invention still further relates to and tradition sugaring system transformed this solute content reduces contains the sucrose syrup to make or to use.

Technical background

Sucrose, C ₁₂H ₂₂O ₁₁, a kind of disaccharides is the condensation molecule that has connected glucose monose and a fructose monose.Sucrose is natural to be present in botanic many fruits and vegetables, for example sugarcane, sugar beet, sweet sorghum, gomuti fibre or sugar maple.In many factors, the processing between the sucrose amount that plant obtains depends on weather conditions in genetic strain, soil or fertilizer factor, the process of growth, plant sickness rate, maturity or harvesting and processes.

Sucrose is concentrated in some position of plant, for example the stem of sugarcane plants or sugar beet root.Can collect the part that sucrose in whole plant or the plant concentrates and shift out (remove) or extract the plant syrup to obtain to contain the syrup of finite concentration sucrose.Usually, the method that from plant materials, shifts out or extract syrup comprise mill, lixiviate (diffusion), squeezing or its combination.Milling is the method that a kind of tradition is used for extracting from sugar-cane syrup.Sugar-cane can be cut into the small pieces of desired size, then by the roller syrup of squeezing out.This process can repeat for several times to guarantee shifting out all sugarcane syrups substantially along a series of runner millings.

Lixiviate is considered to traditional method of extracting syrup from the sugar beet root.Sugar beet is cut into little that is known as " cossettes ", then it is added extraction unit one end, for example making simultaneously, the lixiviate of warm water enters the other end with liquid.When using this convection current to add man-hour, can extract in cossettes or the sugar beet material about 98% sucrose.The liquid that contains sucrose that obtains so-called " leaching syrup ".The cossettes or the sugar beet slices that are come out by extraction unit are still very wet, and still contain some sucrose in its juice (88-92% is a water).Therefore, can in the squeezing machine of screw press or other types, squeeze so that therefrom squeeze out syrup as much as possible these cossettes or sugar beet slices.The pH value of the syrup of this so-called " pulp press water " is approximately 5, and is sent back in the extraction unit in some cases.The beet pulp that obtains (pulp) contains about 75% moisture.In the squeezing charging, add the charged squeezing auxiliary agent of positively charged ion and the moisture content of beet pulp can be reduced about 1.5 to 2%.Also can take out sucrose in the cane stalk by lixiviate.A kind of leach extraction method that is used for sugarcane comprises that the moving-bed of the sugarcane fragment that makes meticulous preparation by extraction unit, can leach sucrose from sugarcane.

Extraction, grinding method, from plant materials, extract syrup or make the plant syrup enter the additive method of the aqueous solution, produce the syrup that contains sucrose, non-sucrose and water.The property quality and quantity of non-sucrose does not wait in the syrup that is made by these methods, can comprise all kinds of botanical derivatives and non-plant derivative, includes but not limited to: insoluble substance, for example vegetable fibre or grogs; And soluble substance, for example carbohydrate, organic and inorganic non-sugar, organic acid, gas dissolved, protein, mineral acid, organic acid, phosphoric acid salt, metal ion (for example iron, aluminium or magnesium ion), pectin, coloring matter, saponin, wax, fat or natural gum, its association or connection portion, the or derivatives thereof beyond fertilizer, sucrose, the sucrose.

These non-sucroses are height lookization, thermally labile or disturb some procedure of processing or the quality or the quantity of sugar product that purifying technique is obtained have a negative impact in others usually.Estimate, average one pound of non-sucrose can make the weight of the sugar product that is obtained by purifying technique reduce 1 to 1.5 pound.Wish can from lixiviate, mill or other is used for extracting from plant materials and separates the syrup that the method for syrup obtains or remove all or part of these non-sucroses.Good lixiviate operation can be removed the impurity that mixes of 25-30%.Beet pulp that reclaims or carbonation extrude water can reduce to 17-20% with this level, but since following some, it remains economical: the sugar of the make-up water of recovery of heat, saving, the contaminated wastewater of reduction, recovery.

Traditional system of processing utilization by lixiviate, mill or other be used for from plant materials extract syrup method (for example United States Patent (USP) 6,051,075,5,928,42,5,480, the method described in 490, each patent all is hereby incorporated by; Or as " SugarTechnology, Beet and Cane Sugar Manufacture (production of sugared technology, beet sugar and sucrose) " (1998) such as P.W.van der Poel; " Beet-Sugar Technology (the beet sugar technology) " that R.A.McGinnis writes, the third edition (1982); Or James C.P.Chen, CaneSugar Handbook:A Manual for Cane Sugar Manufacturers and TheirChemists (the sucrose handbook: the sucrose producer and chemist's thereof handbook) of Chung Chi Chou, method described in the 12nd edition (1993), each document all is hereby incorporated by) the remaining plant materials or the syrup that obtain make following various material: processing is with syrup (process juice); The solid that obtains or in its clarification, purification or treating process, separate with syrup by remaining plant materials from this processing; The syrup that contains sugar or sucrose; The sugar or the sucrose that go out by this syrup crystallization that contains sugar or sucrose; The crystalline mother solution of this sugar or sucrose, with and the various combinations of product or derived products, displacement, every kind of material all contains procedure of processing a certain amount of and described herein or its any part, or the actual compatible impurity of procedure of processing that utilizes in its production, or the impurity compatible with the traditional standard of a class or a kind of following product: wherein a class or a kind of product include but not limited to, removed the animal-feed that contains plant materials of syrup, for example filterable beet section of drop, beet pulp, bagasse, or from processing isolated other solid or syrup the syrup; Using the plant materials of having removed syrup to act as a fuel makes water boiling generation high pressure steam be used for the low-pressure steam of this system of processing or produce low heat to drive turbine generation or to produce with generate energy; To adding the syrup that seasonings and colorant were handled, or adding Nulomoline is to prevent the syrup of crystallization of sucrose, for example golden syrup from the pure sucrose solution syrup of those solution of for example being sold to the industrial user; By removing all or the crystallizable sucrose of any amount or sugared molasses or the molasses derived product that makes, for example molasses (treacle); By the distillable alcohol of molasses; Use sulfurous gas (SO ₂) carry out direct white sugar (blanco directo) or the plantation white sugar (plantation sugar) that sulphiting produces as SYNTHETIC OPTICAL WHITNER; By making the syrup that contains sucrose or sugar boil to juggeri or the raw sugar that substantially dry produces; By melt refining white sugar or the syrup that obtains by the syrup that can further decolour; " or in the whole food industry of North America, be called the monocrystalline sucrose of " evaporation sugar cane juice " (evaporated canejuice) (in order to describe the minimum and monocrystalline sucrose that easily flows that obtains of processing stage) in Britain or other area so-called " not refined sugar " (unrefined sugar), Europe; Grind sucrose (milled cane); Brown sugar (demerara); Muscovado; Rapedura; Panela; Turbina; Contain 94 to 98% sucrose, all the other are molasses, ash content or other micro-raw sugar; Exquisite sugar, for example water white and contain at least 99.9% sucrose, particle is thin especially and its quality for based on specified " bottled " quality of National Soft Drink Association (American soft drinks industry association); Extraordinary white sugar, for example castor sugar, rock sugar, sugar cube or anticorrosion sugar (preservingsugar); By the brown sugar that the method with molasses sprinkling and fusion white refined sugar makes, its characteristic according to molasses can be light brown sugar or dark brown sugar; Or in pulverizing mill by granulated sugar being worn into the Icing Sugar of the various fineness that powder obtains, it can further contain W-Gum or other chemical to prevent caking.This inventory does not represent tradition sugaring system is produced the qualification of product, provides some examples but be expressed as the multiple sugaring system product that is produced.

Be appreciated that traditional system of processing partly comprise gradually clarify, purify or to by lixiviate, mill or other is used for extracting the syrup that the method for syrup obtains from plant materials and carries out the purified step.Usually, can use one or more for example the mechanical means of sieving remove the insoluble or suspended matter of part in the sucrose syrup of containing that derives from plant materials.The filterable syrup of the sieve that obtains when deriving from sugar beet, may contain the sucrose of the water of about 82wt%-85wt%, about 13-15wt%, dissolving non-sucrose or impurity and a certain amount of remaining insoluble substance of about 2.0-3.0wt%.

Usually, can the pH of syrup is raise to the volume that obtains be that the sucrose syrup that contains of 1000 to 2500 gallon per minute is handled by adding alkali gradually.In some traditional system of processing, the pH value of syrup can be from about 5.5pH to approximately being elevated to about 11.5pH to approximately between the 11.8pH between the 6.5pH, thereby make some non-sucrose that is contained in these syrups can reach their iso-electric points separately.This step so-called " preliming ".Yet the back uses this term not represent that the step that will add alkali in containing the sucrose syrup is limited only those systems of processing that the adding of this alkali are called " preliming ".It should be understood that in various traditional syrup systems of processing, wish at first to utilize alkali to make the pH value rising of syrup, carry out procedure of processing subsequently again, for example United States Patent (USP) 4,432, and 806,5,759, described filtration steps such as No. 283; As English Patent 1,043, No. 102 or United States Patent (USP) 3,618,589,3,785,863,4,140,541 or 4,331,483,5,466, described ion-exchange step such as No. 294; As United States Patent (USP) 5,466,294,4,312,678,2,985,589,4,182,633,4,412,866 or 5,102, described chromatographic steps such as No. 553; Or as United States Patent (USP) 4,432, described ultrafiltration steps such as No. 806; As United States Patent (USP) 6,051, described being separated such as No. 075; As United States Patent (USP) 4,045, the 242 described systems of processing that in last carbonator, add active substance, it can be used as the main another kind that adds traditional syrup procedure of processing of ash and carbonation and selects, and above reference is hereby incorporated by.

The use of term " alkali " comprises the material that use can make syrup pH value raise, and includes but not limited to, uses the underflow of the technology of lime or employing lime.The use of term " lime " generally includes concrete use unslaked lime or by heat the calcium oxide that calcium (normally Wingdale form) generates in oxygen.Preferred milk of lime in many syrup systems of processing, its according to following reaction by calcium hydroxide (Ca (OH) ₂) the suspension formation:

Term " iso-electric point " comprises the pH value when solute in the syrup or colloidalmaterial (for example protein) current potential are zero.When these solutes or colloidalmaterial reached its specified iso-electric point, it can form many solid particulates, throw out or cotton-wool thing.

Can in syrup, add the lime carbonate material with further enhancing throwing out, form on this throwing out function can with the core or the substrate of solid particulate or floe binds.This method increases particulate size, weight or density, thereby has promoted the filtration or the sedimentation of these solid particulates or material and promoted it by removing in the syrup.

The mixture of the syrup that obtains, remaining lime, excess calcium carbonate, solid particulate, flocculation agent or cotton-wool thing can be dropped into aforesaid subsequent process steps then.Particularly, about be used for to the syrup that the previous sugar beet course of processing is produced clarify, purification or purified system of processing, can at first carry out cold master and add ash (cold main liming) step so that the Pickering that forms in the preliming step to mixture.This cold master adds grey step can be included in about 30 ℃ of other lime (or adding more according to the quality of preliming syrup) that add the about 0.3-0.7wt% that accounts for the preliming syrup to about 40 ℃ temperature.

Then cold master is added grey syrup and carry out the main ash (hot main liming) that adds of heat further to make Nulomoline and to unsettled other component degradation of this step.Heat is main to be added ash and can comprise further adding lime and be elevated to about 12pH to the level between about 12.5pH so that add the pH value of grey syrup (limed juice).This solvable non-sucrose that causes part not influenced by previous alkali that adds or lime decomposes.Specifically, the heat master who adds grey syrup adds ash and can decompose by the part of Nulomoline, amino acid, acid amides and other dissolving non-sucrose and reach thermally-stabilised.

After cold or hot master adds ash, can add grey syrup to the master and carry out the first carbonation step, in this step, carbon dioxide is added grey syrup with the master and mix mutually.Carbon dioxide reacts with the main remaining lime that adds in the grey syrup and generates the lime carbonate of precipitation form.Not only can remove remaining lime (can remove the remaining lime of about 95wt% usually) by this program, the surfactivity precipitation of calcium carbonate can also be caught quite a large amount of residue dissolving non-sucroses.In addition, precipitation of calcium carbonate can also add physics ash and the carbonation juice and removing the effect of playing flocculating aids in the process of solid matter from main.

Then can with the clarification syrup input that obtains by the first carbonation step other as mentioned above add grey step, heating steps, carbonation step, filtration step, membrane ultrafiltration step, chromatrographic separation step or ion-exchange step or its in conjunction with, replace or the step of deriving, thereby further the syrup that obtains in the first carbonation step is clarified or purified, make the processing syrup of so-called " rare syrup ".

Can carry out multiviscosisty to this further clarifying syrup or " rare syrup " by the method for evaporation section moisture, to obtain tradition and be called the product of " syrup ".The evaporation of part moisture can be carried out in multi-step evaporator.Use this technology to be because it is a kind of mode of effective use steam and if desired, it can also produce the rudimentary steam that another kind can be used for driving follow-up crystallisation process.

The clarification syrup of multiviscosisty or " syrup " can be placed in the container, and this container can hold 60 tons or more usually.In this container, boil and evaporate more water is fit to sucrose or sugar up to environment crystal growth.Because may be difficult to make the crystal of sucrose or sugar to be grown well, the crystal seed that adds some sucrose or sugar is crystal formation to cause.In case crystal grows up to, just can separate crystal that obtains and the mixture that remains syrup.Traditionally, use whizzer to separate this two kinds of materials.Then isolated sucrose or sugar crystal are dried to required humidity, pack subsequently, store, transport or further refining or carry out similar operation.For example, can after transporting to use state, shipment make with extra care raw sugar.

For the product that obtains by plant materials that contains sucrose and syrup, there is an emulative global commerce market.Even the market of the product that is obtained by the plant materials that contains sucrose is enough big so that the reduction slightly of single system of processing step cost also can be saved the money of considerable and required degree.Therefore, the dealer who exists huge motivation to make independent studies person and can make a profit from the chemical of novel system of processing and equipment studies to obtain the system of processing saving the sugaring or the syrup system of sugar industry, and in some cases, the other compensation of the per-cent of this technology saving also is another motivation when making improvements.

Yet, even the improvement at least 1000 years is being established and passed through to the system of processing that the sucrose syrup purifies that contains that obtains from the certain plants body, especially for sugar beet, there be more than 100 year in the industrialization system of processing, even exist huge motivation to promote in sugar or syrup system of processing, to improve, but still there is significant problem in the processing aspect for the syrup that is obtained by plant materials.

A significant problem of tradition sugaring system is acquisition and uses alkali (for example calcium oxide) so that the expense that the pH value that contains liquid sucrose or syrup that is obtained by plant materials raises.As mentioned above, can in syrup, add calcium oxide or calcium hydroxide, from solution, separate out thereby make some solute can be used as solid, throw out or cotton-wool thing to improve the pH value.Calcium oxide obtains by calcined limestone usually, wherein in the presence of oxygen Wingdale is heated in kiln and discharges carbonic acid gas, generates calcium oxide.

As shown in Figure 5, calcine very expensive, because it need buy kiln (40), Wingdale (41) and fuel (42), for example gas, oil, coal, coke etc., these fuel can burn is enough to discharge carbonic acid gas (43) so that kiln temperature is increased to from Wingdale (41).The utility appliance of carrying Wingdale and fuel and shifting out the gained calcium oxide in kiln from kiln must be furnished with some kiln gas of washing and particulate equipment in the kiln waste gas that discharges simultaneously from the limestone calcination process.Naturally manpower be must be equipped with operation and maintenance of equipment, the gas that the quality and will monitoring of the calcined limestone of generation discharges in the kiln operating process and the removing of particulate also will be monitored.

In addition, the calcium oxide of calcining generation must change into calcium hydroxide to be used for typical syrup system of processing.This comprises purchase of equipment again so that calcium oxide is dwindled into the particle of appropriate size and these particles are mixed generation calcium hydroxide with water.Equally, must be equipped with manpower with operation and this equipment of maintenance.

At last, the investment of using relevant equipment and manpower with calcium oxide increases with the increase of consumption.This comprise be used for extra calcium hydroxide and syrup mutually the extra manpower of blended increased point out that perhaps it can comprise the expenditure that equipment increased that the working load capacity is bigger or power is more powerful.

Is the processing of the product of generation when dissolved organic acid or mineral acid react in the processing of excess base or alkali and the syrup with the manufacturing of alkali in traditional system of processing with using another relevant prominent question.For example, when system of processing was used one or more carbonation step when syrup being clarified or purify, the amount of other salt of so-called " used lime " of lime carbonate or generation was in direct ratio with the amount of lime that adds in the syrup.Briefly, the amount of lime that adds in the syrup is big more, and the sedimentary amount that generates in the carbonation step is just big more usually.Can make " carbonatization lime " to be deposited to the carbonation container bottom, be called the material of " lime mud " when being formed with.Can or board-likely separate lime mud by rotary vacuum filter with the frame squeezing machine.The products known as of Xing Chenging " lime cake drainage " (lime cake) then.Lime cake drainage or lime mud can major part be lime deposits, but also can contain sugar, other organic or inorganic thing or water.These isolated throw outs almost always with other system of processing waste material separate treatment, and can, for example, starched with water and the zone that becomes with pump suction settling pond or by dyke or transport to refuse landfill pond (land fills).

Perhaps, can calcine again lime, lime mud or the lime cake drainage of carbonatization.Yet calcining kiln is much also more expensive than the kiln of calcined limestone with the cost of the peripherals that is used for used lime is carried out again.In addition, the quality of incinerating " carbonatization lime " is different with calcined limestone again.It can be to take a single example 92% to 77% that the purity of calcined limestone is compared with calcinating carbonate fossil ash again.Therefore, also corresponding higher to the neutralize amount of required lime kilning again of the oxonium ion of same amount in the syrup.Similarly, the carbon dioxide content of used lime is more much higher than Wingdale.Therefore, not only the manufacturing of calcined limestone is very expensive again, but also the CO that generates when need using much bigger gas duct and equipment to calcine used lime again to shift ₂, need bigger handling equipment to carry again lime kilning, to need bigger carbonation groove or similar devices.

In addition, no matter used lime be disposal in the pond, in the refuse landfill pond or by recycling processing, the amount of lime of using in the particular process system is big more, the expense of usually conduct used lime is just high more.

Another significant problem of tradition sugaring system is that the treatment capacity of system of processing is with processing increasing progressively and successively decrease with employed amount of lime in the syrup.This problem is on the one hand to make or is supplied to the amount or the speed of lime of syrup procedure of processing limited.As mentioned above, must calcine before Wingdale is used as alkali in the syrup system of processing to make calcium oxide.The amount of the lime that obtains is subjected to the restriction of Wingdale utilization ratio, kiln capacity, fuel availability or similar factor.Make lime and can generate size, kind and the quantity of equipment according to lime, available manpower or similar factor and change with the speed of supplying with the syrup system of processing.The amount of lime used in this system of processing that is on the other hand of this problem can make the volume reducing that is used to hold syrup in the system of processing pro rata.For example the increase of the alkali consumption of lime also needs to use bigger volumetrical zone, conduit or similar devices to keep the syrup treatment capacity of equal volume.

Another significant problem of tradition sugaring system is to extract the excessive acid that produces in the plant materials before the plant syrup.Organic acid plays the effect of buffering system in the acid-alkali balance of vegetable cell, thereby keeps required pH value in plant tissue.The source of these acid can be divided into two groups, and first group is the acid that plant absorbs from soil in growth cycle, and second group is the acid that forms by biological chemistry or microbial process.When the acid of absorbing from soil was not enough, plant can be synthesized organic acid, mainly is oxalic acid, citric acid and oxysuccinic acid, with the pH value of the health that keeps plant cell liquor.Therefore, the syrup of extracting from plant tissue contains a certain amount of various organic acid.

Except this in plant tissue naturally occurring organic acid, acid can also mainly form by microbial process in storage process.Serious rotten plant materials may produce lot of organic acids, mainly is lactic acid, acetate and citric acid.Total acid content in the plant tissue can increase three times or more in some cases.

In addition, because the destruction of natural basicity in the syrup can produce carbonic acid gas (CO2) in plant tissue.In this process, bicarbonate ion and carbanion can change into carbonic acid gas.The carbonic acid gas that still keeps dissolved state that generates can produce carbonic acid, and carbonic acid is a source of oxonium ion.Contained organic acid is all or part of in the plant cell liquor, is retained in the syrup that is obtained by plant materials.Therefore, for the pH value that makes syrup raises, must be with alkali these organic and mineral acids that neutralize.The concentration of organic acid or mineral acid is high more in the syrup, and it is just many more to make the pH value of syrup be elevated to the required alkali number of expected value.

Another significant problem of tradition sugaring system is that the plant materials handled with the antimicrobial chemical product or the acid content of syrup are higher than untreated plant materials or syrup.For example, can continuously or add sulfurous gas (SO intermittence ₂) or ammonium bisulfite (NH ₄HSO ₃) to help the controlling microbial growth or to infect.SO ₂Add-on depend on the severity of microorganism growth or infection.Can monitor or follow the trail of to determine the severity of microorganism growth or infection the amount of lactic acid and nitrite.Can use the SO that reaches about 1000ppm ₂Impact or the processing infected system.Can add continuously and reach 400-500ppm with control infection.The SO that is used for antimicrobial protection and adds ₂Or NH ₄HSO ₃The pH value and the basicity of syrup are reduced.Because naturally occurring bicarbonate ion changes into CO ₂Or carbonic acid, basicity can reduce.

Another significant problem of tradition sugaring system is the formation of incrustation scale in the container of for example vaporizer or sugared crystallizer.The calcium salt of oxalic acid constitutes the main component of incrustation scale usually.Oxalate has low solubility in solution, and this solubleness can reduce with the increase of calcium amount in the solution.Even after the syrup purification becomes " rare " or " dense " syrup, also exist abundant calcium to impel oxalate from solution, to separate out in the solution.The method that descale is removed on slave unit surface is very expensive, includes but not limited to by slowing down and efficiency losses with production, or the cost that produced of equipment effective service life reduction.

Another significant problem of tradition sugaring system is not recognize to be used for obtaining the syrup extraction equipment of syrup or the pH value that method can change or reduce the syrup that extracts from plant materials.As for the extraction unit that is used for extracting syrup, do not recognize that the pH value of sugar beet juice can change or reduce in leaching process from the sugar beet material.Be on the other hand the not recognize distinct device or the different methods that are used for from sugar beet material lixiviate syrup of this problem are changing or are reducing the pH value that makes syrup in varying degrees.The improvement of microwave leaching technology has made the pH that makes syrup benefit on duty for the day reduce substantially, and thus, these equipment and method greatly differ from each other from solution provided by the invention.

Another problem of tradition sugaring system be dissolve in from sugar beet extract, shift out or syrup that lixiviate goes out in or add organism, gas dissolved or other material in the syrup that this extracts or lixiviate goes out, before the preliming step that the tradition sugaring is purified, can not tend to be balanced or reach balance with atmosphere dividing potential drop or selected dividing potential drop gaseous mixture.Therefore, solute should be transferred in atmosphere or other the selected gaseous mixture from the syrup of extracting, shifting out or leach, thereby reduce dividing potential drop or the concentration of those solutes in leaching syrup, but now still carry out preliming, initially add ash, lime add step before or directly facilitate simultaneously or combine with other pH regulator method in the syrup and facilitate the reduction of leaching syrup pH value indirectly.As mentioned above, lower pH value can cause using more lime to reach the desired pH of syrup.

Problem about the lixiviate (or other shifts out or extract the conventional method of syrup or material from plant) of traditional sugar beet silk; It is on the one hand traditional extraction equipment or is used for can not providing or be not enough to provide the material of surface interface between the selected or desired gas mixture of the liquid that leaches syrup or contain the plant material that is extracted or removed and atmosphere or other (this interface be used for making being dissolved in leach that syrup or other contain extraction or the liquid of the plant material removed out) to tend to be balanced from other legacy equipment that plant shifted out or extracted syrup or other material, can fully reduce like this these materials and contain concentration in the liquid of the plant material that is extracted or removed at syrup or other.

This problem is that on the other hand traditional sugar beet-leach extraction method or equipment (or be used for removing or extracting from plant materials syrup or other material other legacy equipment) can't provide atmosphere dividing potential drop or other selected dividing potential drop gas in equipment abundant recirculation contains the partial pressure difference between the solute concentration the liquid of the plant material that is extracted or removed to keep syrup or other, this partial pressure difference can reach balance potentially with the dividing potential drop gas that exists on the liquid-vapo(u)r interface, thereby reduces material and realize required leaching in the liquid that syrup or other contain the plant material that is extracted or removed pH effectively, potential or possible reduction.Therefore, the partial equilibrium of dividing potential drop inter gas or complete equipilibrium hinder or have slowed down the further reduction of pH reduction material, compound or gas concentration in the leaching syrup in dividing potential drop gas that exists on the liquid surface and the solution.

This problem third aspect is that traditional sugar beet-leach extraction method or equipment other legacy equipment or the method for syrup or other material (or be used for removing or extracting from plant materials) do not make and leaches the syrup thorough mixing to being enough to that the leaching syrup (or other contains the liquid of the plant material that is extracted or removed) of impelling the reduction of pH value of whole volumes or enough volumes and other gaseous mixture on atmosphere or the liquid-gas interface are tended to be balanced.

This problem fourth aspect is that traditional sugar beet-leach extraction method or equipment other legacy equipment or the method for syrup or other material (or be used for removing or extracting from plant materials) will not leach liquid heat that syrup or other contain the plant material that is extracted or removed and leach syrup or other solubleness that contains the liquid of the plant material that is extracted or removed is reduced to the temperature that is achieved following aspect to being enough to make: the concentration the dividing potential drop gas that the concentration trend liquid-gas interface that makes pH reduce material exists or reach balance with it, or shifting balance point is so that the concentration of pH reduction material is reduced to required, potential or possible concentration; With desired rate or the required potential or possible balancing speed that maybe can reach and the trend of the dividing potential drop gas on the liquid-vapo(u)r interface or reach balance.

Another significant problem of tradition sugaring system is that other that extract or leach syrup its surface exists can be with atmosphere dividing potential drop or syrup cooling the time contains gaseous mixture that greater concn pH reduces material and tend to be balanced or reach balance.When leaching syrup or other and contain the liquid cooling of the plant material that is extracted or removed, the solubleness of atmosphere or other gaseous mixture can increase.Therefore, when leaching the syrup cooling, dissolve in the gas in the syrup or the concentration of other material (including but not limited to that pH reduces material) and improve.Take a single example, before preliming or adding grey step, when the leaching syrup is cooled between about 20 ℃ to about 30 ℃ between about 55 ℃ to about 70 ℃ in the lixiviate step, Atmospheric CO ₂Solubleness increase.Be exposed to CO ₂In the atmosphere dividing potential drop or be exposed to have and be enough to when syrup is cooled off with CO ₂Transfer to the CO in the syrup ₂In the time of in any gaseous mixture of dividing potential drop, the amount when higher with respect to temperature leaches the CO in the syrup ₂Concentration has improved.Leach the CO that improves in the syrup ₂Concentration can reduce the pH value of syrup.Therefore, leach CO in the syrup ₂Or the raising of other gas concentration requires to add at subsequently lime interpolation, preliming or other and adds more lime in grey step to reach required or necessary pH value.

Another problem of tradition sugaring system is the dividing potential drop gas that leaches on the liquid-vapo(u)r interface of liquid that syrup or other contain the plant material that is extracted or removed, and setting up effectively is enough to leaching the concentration that syrup or other concentration gradient essential or that required part is volatilized, moves, removed or otherwise shifts that contains the liquid of the plant materials that is extracted or removed leach the pH value of syrup or reduce pH reduction material in the leaching syrup with abundant raising.

The invention provides a kind of syrup system of processing, it includes equipment and the method that solves above-mentioned each problem.

Summary of the invention

Embodiment

Generally speaking, present invention resides in to evaporate before excess water or the sucrose fractional crystallization and do not adding alkali or adding the syrup system of processing of under the situation of less alkali syrup being purified.Particularly, the invention provides the syrup that solute content reduces, gas dissolved reduces, the pH value is higher or basicity is lower that is used for the syrup purification system.

As mentioned above, can obtain syrup by for example plant materials of sugar beet, sugarcane, sweet sorghum.Naturally, for the product that must obtain syrup with the plant materials of other kind, may there be very big commercial market or niche market (niche markets), and should be appreciated that and the invention is not restricted to the syrup that from any position of the plant of any particular types or plant of collecting or plant materials, shifts out, extract or obtain.In addition, the term syrup can be broadly construed any syrup or the liquid that contains sucrose in any step of any system of processing before sugared crystallization.Thus, contain liquid sucrose or be two examples of syrup by what plant materials obtained by milling or squeezing step by the syrup that the step of lixiviate plant materials makes.As mentioned above, the term syrup comprises the liquid that contains sucrose, non-sucrose and water, and its ratio is indefinite, the step that this depends on the character of plant materials and is used for shifting out from plant materials syrup.Can expect to remove or be partly dissolved thing, because the quality or the quantity of its height lookization, thermally labile or the sugar product that otherwise interferes with each other with some procedure of processing or purification process is obtained have a negative impact.The term syrup also comprises by what these various clarifications or purification step obtained and contains liquid sucrose.

The specific embodiment of the present invention comprises removing and is partly dissolved thing, volatile matter, gas dissolved, water-soluble acid or similar substance at least, for example can form the carbonic acid gas or the sulfurous gas of water-soluble acid, can in solution, produce oxonium ion like this, change the concentration of oxonium ion in the syrup or the pH value of reduction syrup.

For example, when containing enough positively charged ions in the syrup, hydroxide ion OH-can serve as negatively charged ion, and it can make carbonic acid gas CO ₂With carbanion (CO ₃) ^-2, or with bicarbonate ion HCO ₃ ^-Form be dissolved in the syrup.HCO ₃ ^-Disassociation a kind of very weak acid is provided.Yet the positively charged ion that contains in syrup counts deficiency so that dissolved CO ₂When forming carbanion or bicarbonate ion, at carbonic acid gas and carbonic acid H ₂CO ₃Between can produce balance.Carbonic acid can serve as strong acid in the pH scope of preparation syrup.The oxonium ion of Chan Shenging has improved the existing concentration in the syrup subsequently, causes the pH value to reduce.

Similarly, can in syrup, add sulfurous gas (SO ₂) or ammonium bisulfite (NH ₄HSO ₃) with control, reduction or elimination microorganism active, sucrose hydrolysis, the formation of Nulomoline or the loss of sucrose, perhaps the pH value is turned down.Similarly, in syrup, contain enough positively charged ions, for example during calcium, can produce for example sulphite of calcium sulfite.Yet the positively charged ion that contains in syrup counts deficiency so that dissolved sulfurous gas (SO ₂) when forming sulphite, at sulfurous gas (SO ₂), sulfurous acid (H ₂SO ₃) and sulfuric acid (H ₂SO ₄) between can produce balance.Sulfuric acid and sulfurous acid can play the effect of strong acid.The generation of oxonium ion has subsequently improved the existing concentration in the syrup, causes lower pH value.

In addition, plant can produce other water-soluble acid in the normal growth process, and other acid of microbial process generation, include but not limited to phosphoric acid, hydrochloric acid, sulfuric acid, citric acid, oxalic acid, succsinic acid, fumaric acid, lactic acid, oxyacetic acid, pyrrolidone-carboxylic acid, formic acid, acetate, butyric acid, toxilic acid, lactic acid etc.
