Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of method that glucose mother liquid produces high fructose syrup.
Background technology
After producing glucose with crystallization process, remainder raffinate cannot continue crystallization, and we are referred to as glucose mother liquid.Glucose mother liquid is the industrial by product of glucose.Glucose mother liquid waste liquid amount is large, and direct discharge can cause environmental pollution, and how processing glucose mother liquid is the significant problem that glucose production enterprise faces.
Patent CN103981241 discloses a kind of crystallised sugar mother liquor that utilizes for the method for raw material production high fructose syrup, step is as follows: crystallised sugar mother liquor is carried out separating-purifying by simulation moving-bed by (1), the Glucose Liquid of obtained butt glucose content >=90wt%; (2) add water and adjust glucose quality concentration to 30 ~ 35% in Glucose Liquid, adjust pH to 8.0 ~ 8.5, obtained reaction solution, be add magnesium sulfate and Sodium Metabisulfite in the reaction solution of 60 ~ 65 DEG C to temperature, mix, adding liquid isomerase, carrying out isomerization reaction 30 ~ 40h, obtained fruit Portugal raw sugar liquid; Described magnesium sulfate add-on is that every cubic metre of reaction solution adds 550 ~ 850g, and Sodium Metabisulfite add-on is that every cubic metre of reaction solution adds 150 ~ 350g, and liquid isomerase add-on is 2 ~ 6 ‰ of reaction solution volume percent; (3) pH to 4.0 ~ 4.5 of the fruit Portugal raw sugar liquid that regulating step (2) is obtained, add gac, are warming up to 70 ~ 85 DEG C, and insulation absorption 20 ~ 40min, filters, obtained decolouring fruit Portugal raw sugar liquid; (4) decolouring fruit Portugal raw sugar liquid obtained for step (3) is carried out ion-exchange through ion exchange resin, obtained desalination high fructose syrup liquid; (5) the desalination high fructose syrup liquid warp by obtained for step (4) is concentrated, obtained high fructose syrup.This utilizes crystallised sugar mother liquor to mainly contain following defect for raw material production high fructose syrup:
(1) have employed simulated moving bed chromatography in prior art to be separated glucose mother liquid.Adopt simulated moving bed chromatography to be separated this method, need mother liquor raw material to carry out pre-treatment, the cost that puts into operation is too high.
(2) produce greatly, the initial dry-matter of glucose mother liquid is 45-55%, after adopting simulated moving bed chromatography to be separated, needs, by after the Glucose Liquid dilution that obtains, just to react with isomerase.This step glucose mother liquid first being concentrated to redilution, considerably increases the workload in glucose mother liquid treating processes and time working hour, is unfavorable for processing glucose mother liquid in the large production of industry.
(3) adopt liquid isomerase in prior art, the utilization ratio of liquid isomerase is lower.
(4) glucose is before isomerization, needs to add three kinds of auxiliary materials, the first adjust ph adopted in patent CN103981241, after add magnesium sulfate and Sodium Pyrosulfite, this is unfavorable for the stability contorting of material pH value.After adding magnesium sulfate and Sodium Pyrosulfite, easily cause the change of pH value, be unfavorable for the strict pH value controlling reaction.
(5) adopt simulated moving bed chromatography to be separated glucose mother liquid and easily produce byproduct, the byproduct inconvenience process obtained, yield is on the low side.Glucose mother liquid processing cost is high.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of method that glucose mother liquid produces high fructose syrup.The method operation steps is simple, the advantage that processing cost is low.
The present invention is realized by following technical scheme:
Glucose mother liquid method produces a method for high fructose syrup, comprises the steps:

(4) step (3) obtains rare high fructose syrup by ion exchange column, and make high fructose syrup pH value return between 3.3-4.5, conductance is reduced to below 20us/cm;
A large amount of magnesium ion, sodium ion, sulfate radical, carbonate is contained by the reaction solution after isomerase process, inferior sulfate radical, the material containing foreign ion, if without removal, color and luster and the ash content index of product can be had influence on, need again through ion exchange column.This ion exchange column is identical with the mechanism of action of mother liquor ion exchange column, adopts hydrochloric acid and liquid caustic soda wash-out.Through the regulating effect of ion exchange column, make the pH value of high fructose syrup return between 3.3-4.5, conductance is reduced to below 20us/cm, and the high fructose syrup under this condition is the script pH value of liquid glucose, and the color of product and mouthfeel are also optimum regimes.
(5) 4.5 ‰ gacs are added in butt ratio in the high fructose syrup obtained to step (4), be warmed up to 65-70 DEG C, filter after maintaining 30min, filtrate evaporation concentration makes dry-matter reach more than 75%, cool to less than 40 DEG C again, obtain high fructose syrup finished product.High fructose syrup is through a series of conversion, absorption, high temperature, under the acting in conjunction of the conditions such as soda acid, some pigments can be produced, finally can affect the sense index of finished product, therefore, need again through the adsorption of gac, the coloring matter in removing syrup, filter type is identical with mother liquor decolorization filtering mode.
The glucose dry matter content that isomerase can transform is greatly about about 50%, and such high fructose syrup is not easy to store transport, needs to remove moisture unnecessary in syrup, improves dry matter content to 75%.High fructose syrup after decolouring, is subject to the concentrated of vaporizer, makes dry reach more than 75%, then through cooling to less than 40 DEG C, be stored in finished product storage tank.
Above-mentioned glucose mother liquid method is produced in the method for high fructose syrup, and in described step (1), the addition of gac is 7 ‰.
Above-mentioned glucose mother liquid method is produced in the method for high fructose syrup, and described step (2) intermediate ion exchange column is zwitterion hybrid resin exchange column.
