Problems solved by technology

In this production process, the powder milk liquid from the twelve-stage cyclone directly enters the liquefaction production process of starch sugar or enters the dehydration and drying process. Since the protein content of the powder milk after passing through the twelve-stage cyclone scrubber is still maintained at 0.45 %, leading

Abstract

A protein processing method in starch production is disclosed. According to the method, starch milk obtained through cyclone separation is processed by feeding micro bubbles into the starch milk, and a protein-rich solution recovered matter is collected, is returned to the previous protein processing step and is processed. Proteins in a starch milk cleaning step are removed in one step by the method. The method can reduce the protein content of the starch milk, increases the yield of protein powder, improves product quality, and reduces the production cost of each ton of starch.

Description

technical field [0001] The invention relates to the field of cornstarch production, in particular to a protein treatment method in starch production, which is mainly to further remove the protein in the cleaning process of starch milk. Background technique [0002] At present, corn starch processing enterprises generally adopt the wet grinding process for production. In the wet grinding process, the corn starch is coarsely ground and finely ground and then enters the separator for protein separation to obtain crude starch milk. However, the crude There is still a small amount of protein in starch milk, so it must be washed with tap water in a cyclone washer. At present, 12-stage cyclone washer is generally used in production. In this production process, the powder milk liquid from the twelve-stage cyclone directly enters the liquefaction production process of starch sugar or enters the dehydration and drying process. Since the protein content of the powder milk after passing...
