Abstract
The invention discloses a glucose mother liquor recycling process. Purified glucose liquor sequentially undergoes concentration, first crystallization and separation to obtain a glucose product. Purity of mother liquor obtained after separation is 85-87%, the mother liquor of the concentration is divided into two parts, one part serves as a raw material for cooling and recrystallization, glucose liquor with the purity more than 98.5% is obtained after separation, purity of the mother liquor after separation is less than 75%, and the other part returns to the step before crystallization and is crystallized with the concentrated glucose liquor together. Therefore, the discharge amount of the mother liquor is greatly reduced, the added value of the product is increased, and the yield of crystallized glucose is improved.
Description
Technical field
The present invention relates to the glucose production technical field, particularly relate to a kind of glucose mother liquid recycling technique.
Background technology
After Crystallization Separation glucose, separating after product has two kinds: the one, and crystalline product glucose; The 2nd, glucose mother liquid, stay a large amount of mother liquors, and after its separating, washing, mother liquor purity is 85%-87%, because this mother liquor dry concentration is low, and very easily fermentation, storage period is short, and commodity value is low, with cheap selling, processes; For this problem, need to recycle technical study to mother liquor, the quantity discharged of for making with extra care glucose, supplying raw materials and greatly reducing mother liquor, reduce the production run load, improves product yield.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of glucose mother liquid recycling technique for the defect of above-mentioned existence, and low pure mother liquor is carried out after recrystallize dissolving, and the Glucose Liquid of purity >=98.5% can be for the production of in purifying high-purity DEXTROSE MONOHYDRATE BP crystallisation process.So not only greatly reduce the quantity discharged of mother liquor, increased the additional value of height of product, and improved the crystallization glucose yield.
A kind of glucose mother liquid recycling process technology scheme of the present invention is, liquid glucose after refining obtains glucose product and mother liquor through concentrated, primary crystallization, separation successively, separate the mother liquor part the obtain recrystallization of being lowered the temperature, obtain the Glucose Liquid of purity >=98.5% after again separating, before another part returns to enrichment step, with together with liquid glucose after refining, concentrated, primary crystallization.
Concrete steps are:
1. refining: Glucose Liquid enters ion-exchanger, carries out desalting treatment through ion exchange resin and obtains refining liquid glucose;
2. concentrated: refining liquid glucose is concentrated through mechanical commprssor and liquefaction used heat evaporation unit;
3. primary crystallization: after concentrated, Glucose Liquid, in crystallizer, carries out decrease temperature crystalline, when crystallization yield reaches 55%, carries out next step;
4. separate: the crystallization liquid glucose enters separating machine to be separated, and the crystallization Icing Sugar enters drying section production DEXTROSE MONOHYDRATE BP, purity > 99.5%;
5. mother liquid disposal: 4. step is separated the rear portion mother liquor and is returned and be fitted on step and 2. together with Glucose Liquid, carry out enrichment step, another part mother liquor carries out recrystallization, the sugar crystal that recrystallization obtains separates again, then after separating the Icing Sugar obtain and being dissolved, as the crystallization raw material of refining glucose.
Step is the specific conductivity of refining liquid glucose≤50 μ s/cm 1..
Sugar concentration after 2. step concentrates is 68-75%;
Step 3. decrease temperature crystalline adopts the gradient cooling crystallization, and 0.5-2 ℃ lowers the temperature at every turn.
Step obtains mother liquor purity after 4. separating be 85%-87%.
The step mother liquor purity that 5. recrystallization obtains≤75%, can sell processing.
The step Icing Sugar purity that 5. separation obtains again >=98.5%.
Beneficial effect of the present invention is: a kind of glucose mother liquid recycling technique of the present invention, low pure mother liquor is carried out dissolving after recrystallize, and the Glucose Liquid of purity >=98.5% can be for the production of in purifying high-purity DEXTROSE MONOHYDRATE BP crystallisation process.So not only greatly reduce the quantity discharged of mother liquor, increased the additional value of height of product, and improved the crystallization glucose yield.Concrete effect is as follows:
1. the quantity discharged of mother liquor reduces; Crystallization workshop section in dextrose production process, crystallization is to remove impurity, the process that is crystal with recombine between molecule, also be considered as the process of purifying.By hanging down the utilization of purification again of pure mother liquor, thereby greatly reduced the quantity discharged of crystalline mother solution.
2. the purity drop of mother liquor is to≤75%; For guaranteeing the top grade purity of crystalline dextrose > 99.5%, thus the former liquid glucose purity while having determined crystallization > 92%, and the mother liquor purity after its crystallised sugar separation 85%.Apply after purification again by mother liquor, guaranteed that the purity of mother liquor is reduced to≤75%, thereby reduced the quantity discharged of mother liquor.
3. the production for refined sugar in crystals provides the high purity raw liquid glucose; The mother liquor produced after separating in top grade crystallised sugar production process, after purifying, the purity of its crystallised sugar is still very high again, its content >=98.5%, after highly purified crystallised sugar like this dissolves, through practical proof, it can be used for producing refining DEXTROSE MONOHYDRATE BP.
4. raising crystallization yield, the commodity yield improves 3%.By the conversion recrystallization of low dense mother liquor, can greatly improve the commodity yield of crystallised sugar, reduce mother liquor output.
5. the extraction and application again of mother liquor, this technique is extracted for refining glucose production from low pure mother liquor again: 1. for mother liquor: mother liquor per ton extracts and obtains crystallised sugar dry 500kg, be converted into refining glucose 400kg, 4500 yuan/t of refined sugar, mother liquor create beneficial result per ton is: 4500 yuan/t * 0.4t=1800 unit.2. for commodity, consider: the yield of commodity glucose: the sugared 50kg*4500 of 85%-90% → 1 ton of starch fecund unit=225 yuan; The quantity discharged of mother liquor: 18%-11% → 1 ton of starch mother liquor amount reduces 70kg*1200 unit=84 yuan.
