Abstract

The invention discloses a countercurrent slurry cyclic immersion process used in cornstarch processing, which is characterized in that the process comprises the steps of immersing corn into a plurality of immersion tanks containing immersion slurry for 48-52 hours, wherein the immersion slurry is composed of 0.16-0.18% sulfurous acid and water, and has temperature of 48-50DEG C; and the plurality of immersion tanks communicate with each other. The corn is cyclically immersed in the immersion tanks, instead of the conventional stationary corn immersion. By cyclic immersion of the corn, the endosperm of the corn is effectively swollen, and the total starch yield is improved.

Description

Counterflow Slurry Circulation Soaking Technology in Corn Starch Processing technical field The invention belongs to the technical field of corn deep processing. Background technique Corn starch is a natural polymer material with unique properties. It is widely used in high-grade food, pharmaceutical and other materials, and its economic benefits are very significant. The production principle and equipment of corn starch are basically the same, but if corn starch is produced simply by using the starch production method and equipment of existing starch factory to produce corn starch, it will lead to the following disadvantages: the total output rate of corn starch factory is low, only It reaches about 90%, and the acidity in the starch is much higher than the national standard. The production time per unit of output is long, and the cost of the product is high. The specific analysis is as follows: Because the basic process of corn starch production is: soak the raw corn, ...
