Embodiment Construction
[0022] The present invention is specifically described below in conjunction with accompanying drawing, as figure 1 As shown, a corn starch production process includes material selection and removal of impurities 1, washing and soaking 2, mechanical crushing 3, separation and embryo extraction 4, coarse grinding 5, protein separation 6, refining 7, dehydration 8, drying 9, and packaging 10. Wherein: the material selection and impurity removal 1, selecting high-quality raw corn, threshing, and putting it into a corn drum sieve for impurity removal; the washing and soaking 2, cleaning the corn after impurity removal, and putting it into a corn mixing box mixed with dilute corn syrup, and then sent to the soaking tank for soaking; the mechanical crushing 3, the soaked corn was taken out, separated from the soaking liquid, and then put into a crushing box for mechanical crushing; the separation and embryo extraction 4. Separating the corn germ and corn endosperm from the broken cor...

The invention discloses a corn starch production process which comprises the following steps of selecting materials and removing impurities, washing and soaking, performing mechanical crushing, separating and taking corn embryos, performing coarse grinding, separating proteins, refining, dehydrating, drying and packaging. The method specifically comprises the following steps: selecting high-quality corn raw materials, threshing and removing impurities; cleaning the corn subjected to impurity removal, mixing with dilute corn steep liquor in a corn mixing box, and soaking; taking out the soaked corn, separating, and performing mechanical crushing; separating the corn embryos from corn endosperm of the corn; grinding; performing protein separation; refining the starch in which most of proteins are completely separated; dehydrating the refined starch in a dehydration device; feeding the dehydrated starch milk into a drying box for drying; and finally, packaging. The corn starch production process disclosed by the invention has the beneficial effects that the process is simple in process, less in impurities and complete in starch separation; and due to the steps of grinding, milling, refining, recovering and re-milling, the extraction rate of the starch is increased, the production cost is low, and the starch quality is high.
Description
technical field [0001] The invention relates to the field of food processing technology, in particular to a corn starch production technology. Background technique [0002] At present, in the domestic traditional starch production process, the dehydration of refined starch milk adopts a horizontal siphon scraper centrifuge. Through the dual action of centrifugal force and siphon suction, solid-liquid separation is realized. The dehydration filtrate and siphon liquid of the scraper centrifuge are discharged to the waste water pool. The corn steep liquor produced by the soaking process of starch production is evaporated and concentrated to obtain concentrated corn steep liquor, and the steam condensate is discharged to the waste water tank, which will generate a large amount of waste water during production, increase power consumption and water consumption, and also cause a burden to the subsequent sewage treatment plant. [0003] For example, the prior art CN102070721A disclo...
