Abstract

The invention relates to a processing technology of distiller's grain feed. The processing technology comprises the steps that ethanol dehydrogenase is added into distiller's grains, after enzymolysis is performed for 2-3 hours, acetaldehyde dehydrogenase is added for enzymolysis, enzymolysis materials are dried until the water content is lower than 10%, and a dried mixed material is obtained; the dried mixed material is put into a bulking machine to be bulked, a bulked mixed material is obtained, the bulked mixed material is smashed to be 40-50 mesh, and then the distiller's grain feed is obtained. According to the processing technology, after the distiller's grains are treated through ethanol dehydrogenase and acetaldehyde dehydrogenase, the protein content in the distiller's grains can be significantly increased, cellulose pectin substances in the distiller's grains can be effectively degraded into monosaccharide and oligosaccharide, multiple organic acids and vitamins are generated, and the nutritional value and aroma of the distiller's grains are improved; the rice hull fiber tissue treated through a bulking technology is in a fluffy state and is easy to digest and absorb, the dissolution rate of the nutrients in rice hulls can be increased, and the bulked distiller's grains are good in solubility and palatability and can be easily digested by livestock.

Description

A kind of processing technique of lees feeds

Technical field

The present invention relates to the production method of a kind of feedstuff, be specifically related to the processing technique of a kind of lees feeds.

Background technology

Distiller grains are the direct leftover bits and pieces during wine brewing, it does not contain only a certain proportion of grain can save the concentrate feeding cattle, it is possibly together with abundant crude protein, about exceed 23 times of Semen Maydis content, simultaneously possibly together with various trace elements, vitamin, yeast etc., the content of lysine, methionine and tryptophan is the highest, this is that agricultural crop straw is not provided that, distiller grains are excellent protein resources, but owing to hindering material-rice husk containing more nutrition, it is impossible to be directly used as feedstuff, make waste disposal more, not only cause the wasting of resources, and pollute environment.

Summary of the invention

For making full use of abandoned vinasse of the prior art, it is an object of the invention to provide the processing technique of a kind of lees feeds.

The technical solution used in the present invention is, the processing technique of a kind of lees feeds, and it comprises the steps of

nullThe weight ratio pressing 10:0.1 in distiller grains adds ethanol dehydrogenase，It is 100-120mpa at pressure、Temperature be 35-38 DEG C in the environment of enzymolysis 2-3 hour，Compound is stirred by enzymolysis simultaneously，Stir speed (S.S.) is 120 revs/min，Obtain the first enzymolysis compound，The weight ratio pressing 10:0.15 in the first enzymolysis blended stock adds aldehyde dehydrogenase，It is 130-150mpa at pressure、Temperature be 32-34 DEG C in the environment of enzymolysis 40-50 minute，First enzymolysis blended stock is stirred by enzymolysis simultaneously，Stir speed (S.S.) is 160 revs/min，Obtain the second enzymolysis compound，Second enzymolysis compound is dried at a temperature of the drying of 60-65 DEG C to water content less than 10%，Obtain drying compound，Drying compound is put into bulking machine，It is 85-90 DEG C in temperature，Pressure is 270-280kg/cm²Under conditions of expanded, obtain expanded compound, expanded compound be crushed to 40-50 mesh, obtain lees feeds of the present invention.

Distiller grains enough increase substantially the protein content in distiller grains after ethanol dehydrogenase and acetaldehyde-dehydrogenase ferment treatment, effectively the cellulose pectic substance in distiller grains can be degraded to monosaccharide and oligosaccharide, and generate multiple organic acid, vitamin, improve nutritive value and the fragrance of distiller grains, rice hull cellulose tissue after bulking process processes is fluffy state, it is easy to digested absorption, can improve the dissolution rate of nutrient in rice husk, the distiller grains dissolubility of after the swelling and palatability more carefully, are easily digested by domestic animal.
