Problems solved by technology

The sugar grains in the liquefaction liquid also contain a certain amount of sugar, but this part of sugar is usually discarded as non-transformable substances, which fails to fully utilize the raw materials, and is also due to the low conversion rate of starch in the starch sugar manufacturing process. one of the reasons for the high
In addition, because the sugar liquid produced by traditional techniques contains a lot of impurities such as protein and fat, filter aids such as diatomite or perlite and activated carbon must be used to decolorize and filter the sugar liquid smoothly. Sugar grains containing filter aids or activated carbon It cannot be reused and can only be discharged as solid waste, causing adverse effects on the environment

Abstract

The invention discloses a production method for starch sugar. The production method comprises steps of purified water preparation, slurry mixing, liquefaction, saccharic recovery, saccharification, filtering without solid waste, preconcentration, ion exchange refining and concentration. In the technology, condensed water generated in the production process is recovered and purified water with a conductivity of less than 3 microsiemens / cm and with a 2-AP content of less than or equal to 0.2 microgram / L. When the water is used for slurry mixing, impurities in sugar solution can be reduced. The starch milk temperature is kept at 60-63 DEG C, starch particles can swell up fully, and the starch sugar dry product yield is raised. The two-stage saccharification technology is employed, generation of adverse products of 2-AP or the like is reduced, and the sugar yield is further raised. Sugar-free grains generated in the production process can be employed as an animal feed additive, and no solid waste is discharged. After the technology is employed, the starch sugar dry product yield reaches more than 108%, the sewage amount is lowered by 50%, the COD total amount is reduced by more than 50%, and the production method makes a substantial progress compared with a traditional starch sugar production technology, and plays an active role in environment protection.

Description

technical field [0001] The invention belongs to the field of starch sugar processing, in particular to a production method of starch sugar. Background technique [0002] Starch sugar is widely used in beverages, candies, pastries, beer and other foods, because its price is lower than that of sucrose and its use is simple, so it is favored by many end food companies. [0003] At present, the condensed water produced during the evaporation and concentration of starch sugar contains 2-aminoacetophenone (2-AP for short) and other substances that are not expected by the product. This water cannot be directly used for starch preparation, so the water used for starch sugar production is mainly Purified tap water needs to consume a lot of natural resources, which is not conducive to environmental protection. The traditional starch sugar manufacturing process is to return the sweet water to the pulping process. The reducing sugar in the sweet water and the amino acid substances in t...
