Soybean dietary fiber processing technology

Abstract

The invention relates to a production technology for processing by-products left after processing of soybean protein isolate into soybean dietary fiber powder. The processing technology comprises steps as follows: residues are obtained from soybean protein isolate and conveyed to a temporary storage tank for low-temperature storage; the stored residues are sterilized; the sterilized residues are put in a dehydrator for dehydration, and a filter cake is obtained; the dehydrated filter cake is conveyed to a crusher and conveying integrated machine through a belt and conveyed to a flash dryer; the temperature of a dried material is 35-50 DEG C, and the material is separated by an air cooling, conveying and separation integrated machine system and then enters a temporary storage bin; a semi-finished product is ground by an ultra-fine grinder into 80-300 meshes after drying and cooling; the ground material is screened and subjected to anti-dust treatment, and soybean dietary fibers can be obtained.

Description

technical field [0001] The invention relates to a production technology invented for processing the remaining by-products after processing soybean protein isolate into soybean dietary fiber powder. Background technique [0002] At present, the remaining bean dregs after the application of soybean protein isolate are directly fed to livestock such as cattle, sheep, pigs, etc. for use as feed. [0003] The current drying process of bean dregs is relatively backward. Due to the unfavorable storage of soybean protein bean dregs raw materials, bacteria often increase, and the deteriorated products produce peculiar smell. Due to the improper drying process and equipment, the drying technology is backward and consumes a lot of money, and paste is prone to appear. Black spots, peculiar smell, etc. have seriously affected the quality and application range of bean dregs fiber. [0004] The current bean dregs drying process has low production capacity and high consumption. Contents ...
