Embodiment Construction

[0012] The present invention is further illustrated below by way of examples.

[0013] The processing technology of corn starch is characterized in that: comprising the following steps, corn storage and purification, corn soaking, corn crushing, fine grinding, fiber separation, washing and drying, starch separation, washing and drying;

[0014] Corn storage and purification: The raw corn is weighed and added to the raw material warehouse, purified by vibrating screening, stone removal, magnetic separation and other processes, and then purified in the corn warehouse after weighing;

[0015] Corn steeping is carried out countercurrently in an aqueous solution of sulfurous acid;

[0016] The soaked corn is broken into 4-6 petals by the wet corn conveying pump through the stone remover, and then into the first convex tooth mill, and the corn is broken into 4-6 petals. % to 85% of the germ, while releasing 20% ​​to 25% of the starch;

[0017] The soaking solution after soaking, t...

Abstract

The invention discloses a corn starch processing technology and relates to the technical field of starch processing. The corn starch processing technology is characterized by comprising the following steps: storage, purification, soaking, crushing and fine grinding of corn, separation, washing and drying of fiber, and separation, washing and drying of starch, wherein the crushing of corn is that soaked corns enter a wet corn storage hopper from a wet corn delivery pump via a stone removal device and then enter a first convex teeth mill to be crushed into four to six pieces, the content of entire corns is not greater than 1%, 75-85% of germs are separated, and 20-25% of starch is released. According to the processing technology, the process is reasonable, the speed and the efficiency are high, and the prepared starch is fine and high in quality.

Description

Technical field: [0001] The invention relates to the technical field of starch processing, in particular to the processing technology of corn starch. Background technique: [0002] Corn originated in South America, and then spread to Asia from Europe and Africa. Corn has been cultivated in my country for more than 470 years. Corn, also known as sorghum, is one of the three major food crops in the world and an important feed material. Because it is a dry land crop, it has high yield per unit area and great potential for increasing production, so it plays an important role in agricultural production. Corn wet milling is the process of separating the main components of corn kernels by physical methods to obtain corresponding products. Five main components are obtained through this process: starch, germ, soluble protein, skin residue (fiber), and gluten (protein). Because the proportion of starch contained in corn is the largest, generally about 70% on a dry basis, it is custo...
