Problems solved by technology

[0002] Distiller's grains are the direct leftovers in the brewing process. It not only contains a certain proportion of grain, which can save the concentrate for feeding cattle, but also contains rich crude protein, which is about 2-3 times higher than that of corn. It also contains various trace amounts Elements, vitamins, yeast, etc., the content of lysine, methionine and tryptophan is also very high, which cannot be provided by crop straw. Distiller's grains are excellent protein resources, but because they contain more nutrient-blocking substances-rice Shells cannot be used directly as feed, and are often treated as waste, which not only causes waste of resources, but also pollutes the environment

Embodiment 1

[0008] Add alcohol dehydrogenase to the distiller's grains in a weight ratio of 10:0.1, and perform enzymatic hydrolysis for 2 hours at a pressure of 100mpa and a temperature of 35°C, and stir the mixture at the same time, at a stirring rate of 120 rpm. To obtain the first enzymolysis mixture, add acetaldehyde dehydrogenase to the first enzymolysis mixture in a weight ratio of 10:0.15, and enzymolyze it for 40 minutes at a pressure of 130-mpa and a temperature of 32°C. At the same time, the first enzymolysis mixture was stirred at a stirring rate of 160 rpm to obtain the second enzymolysis mixture, and the second enzymolysis mixture was dried at a drying temperature of 60°C until the water content was lower than 10%, to obtain the dried mixture, put the dried mixture into the extruder, at a temperature of 85°C and a pressure of 270kg / cm 2 Under the conditions of puffing, the puffed mixture is obtained, and the puffed mixture is crushed to 40 meshes to obtain the distiller's gr...

Embodiment 2

[0010] Add alcohol dehydrogenase to the distiller's grains at a weight ratio of 10:0.1, and perform enzymatic hydrolysis for 3 hours at a pressure of 120mpa and a temperature of 38°C, and stir the mixture at the same time, at a stirring rate of 120 rpm. To obtain the first enzymatic hydrolysis mixture, add acetaldehyde dehydrogenase to the first enzymatic hydrolysis mixture at a weight ratio of 10:0.15, and perform enzymatic hydrolysis for 50 minutes at a pressure of 150mpa and a temperature of 34°C. Stir the first enzymolysis mixture at a stirring rate of 160 rpm to obtain the second enzymolysis mixture, and dry the second enzymolysis mixture at a drying temperature of 65°C until the water content is lower than 10% , to get the dried mixture, put the dried mixture into the extruder at a temperature of 90°C and a pressure of 280kg / cm 2 Under the conditions of puffing, the puffed mixture is obtained, and the puffed mixture is crushed to 50 meshes to obtain the distiller's grain...

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

technical field [0001] The invention relates to a production method of feed, in particular to a processing technology of distiller's grain feed. Background technique [0002] Distiller's grains are the direct leftovers in the brewing process. It not only contains a certain proportion of grain, which can save the concentrate for feeding cattle, but also contains rich crude protein, which is about 2-3 times higher than that of corn. It also contains various trace amounts Elements, vitamins, yeast, etc., the content of lysine, methionine and tryptophan is also very high, which cannot be provided by crop straw. Distiller's grains are excellent protein resources, but because they contain more nutrient-blocking substances-rice Shells cannot be directly used as feed, and are often treated as waste, which not only causes waste of resources, but also pollutes the environment. Contents of the invention [0003] In order to make full use of the waste distiller's grains in the prior ...
