Embodiment 1

[0041] A kind of production improvement method of cornstarch, concrete steps are as follows:

[0042] a. Purification process

[0043] The raw corn is sent to the metering scale through the bucket elevator, and then sent to the multi-stage self-horizontal vibrating screen after metering. The impurities larger than the corn are screened out by the first sieve, and the impurities smaller than the corn are screened out by the second The sieve is removed from the bottom of the sieve, and the side-by-side stone impurities with the same volume as the corn enter the corn washing tank together with the corn. The impurities are blocked by the multi-level vertical ladder baffle in the washing tank, and the metal impurities are attracted by the magnet in the tank, and are removed after parking. Light and small corn dust and corn coat impurities are sucked away by the induced draft fan from the outlet of the bucket elevator and the inlet of the multi-stage vibrating screen and stored in t...

Abstract

Belonging to the technical field of corn starch production, the invention in particular relates to a production improvement method for corn starch. The method consists of a purification process, an acid making process, a soaking process, a crushing section, germ separation drying, fiber washing and drying, protein concentration drying, starch milk refining, as well as starch dehydration and drying. The method is characterized in that the technical scheme of adding a compound enzyme composed of cellulose, xylanase, pectinase and mannanase into a crushed corn slurry plays a significant role in separating all corn components, thus facilitating production and processing of corn starch, and greatly improving the production level of corn starch.

Description

technical field [0001] The invention belongs to the technical field of corn starch production, in particular to an improved production method of corn starch. Background technique [0002] In the production process of corn starch, the most advanced, typical and reliable corn wet production process in the world is adopted, and the whole production process is a thermal cycle closed production. [0003] At present, according to the "National Environmental Protection Standard of the People's Republic of China" (HJ445-2008) in the "Clean Production Standard Starch Industry", the main indicators of the domestic advanced level of the corn starch processing industry are: the yield of corn starch is ≥ 68%; Rate ≥ 95%; power consumption ≤ 220kwh / t starch. [0004] The patent application with the application number 2011101182427 discloses a method for enzymatically producing corn starch. Cellulase and xylanase are mixed and added, but the effect obtained cannot reach the international ...
