Problems solved by technology

The main components in the waste grains are residual starch, crude protein, crude cellulose, crude fat, crude vitamins and many trace elements. Due to the large amount of chaff fibers, these are not easy to be digested and absorbed by animals. The water content is high, the acidity is high, and it is easy to spoil and deteriorate. It is not suitable for long-term storage and transportation. Therefore, many wastes can only be piled up on the spot. Air and nearby surface water cause serious pollution, which not only causes environmental pollution but also causes serious waste of resources

Embodiment 1

[0015] 1) raw material pretreatment: use a disperser to disperse the fresh distiller's grains into uniform particles, and the diameter of the particles is about 1.5 mm;

[0016] 2) Defibrosis treatment: screen out spores, add 98% of the original grain, 0.9% of starch and 1.1% of soybean powder to it, perform solid-state fermentation, maintain the highest cellulase activity of 14.204U / mL, and obtain distilled grains;

[0017] 3) Fermentation: screen out Candida and Pichia pastoris, the ratio of Candida and Pichia pastoris is 1:1, the inoculum size is 10%, distilled grains are 87%, bran 10%, ammonium sulfate 1.5%, Quicklime 1.5%, solid state fermentation 60h.

[0018] Part of the distiller's grains were dried in the sun, and the true protein and fibrosis were detected. The test results showed that the true protein content of the distiller's grains reached 23.63%, which was 75.95% higher than that of the original distiller's grains. The content is reduced by up to 80%, which is ...

Embodiment 2

[0020] The difference between this embodiment and embodiment 1 is that step 2) and step 3) are carried out under sterilized process conditions.

[0021] Part of the processed liquor distiller's grains was dried in the sun, and the true protein and fibrosis were detected. The test results were: under the sterilization process conditions, the true protein content of liquor distiller's grains reached 17.23%, which was higher than that of the initial discarded grains. 28.29%, the content of crude cellulose in liquor lees is reduced by 80%, which is more suitable for animal digestion and absorption.

Embodiment 3

[0023] 1) raw material pretreatment: use a disperser to disperse the fresh distiller's grains into uniform particles, and the diameter of the particles is about 1.5mm;

[0024] 2) Defibrosis treatment: screen out the spores, add 97% of the original grains, 1.5% of the starch and 1.5% of the soybean powder to it, solid-state fermentation, maintain the highest cellulase activity of 14.204U / mL, and obtain the distilled grains;

[0025] 3) Fermentation: screen out Candida and Pichia pastoris, the ratio of Candida and Pichia pastoris is 1:1, the inoculum size is 10%, 85% of distilled grains are discarded, 11% of bran, 2% of ammonium sulfate, Quicklime 2%, solid state fermentation 60h.

[0026] Part of the distiller's grains were dried in the sun, and the true protein and fibrosis were detected. The test results showed that the true protein content of the distiller's grains reached 23.31%, which was 74.91% higher than that of the original distiller's grains. The content is reduced ...

Abstract

The invention relates to a method for producing a high-protein feed from waste distiller's grain of Baijiu, which includes the following steps: (1) material pretreatment: a beater is used for beatingfresh raw distiller's grain of Baijiu into uniform particles, and the diameter of the particles is about 1.5mm to 3mm; (2) defibering treatment: endospore-forming bacteria are screened out and added with 98 to 98.5 percent of raw distiller's grain, 0.9 to 1 percent of starch and 1 to 1.1 percent of soybean flour, solid-state fermentation is carried out, cellulase activity is kept as high as 14.204U / mL, and thereby waste distiller's grain of Baijiu is obtained; (3) fermentation: candida and pichia pastoris are screened out, the proportion of candida to pichia pastoris is 1:1, the inoculation amount is 10 percent, and with 85 to 89 percent of waste distiller's grain of Baijiu, 9 to 11 percent of bran, 1 to 2 percent of ammonium sulfate and 1 to 2 percent of quick lime, solid-state fermentation is carried out for 60 hours. By means of modern microbial technology, the method decomposes substances in the distiller's grain, such as residual starch, crude protein, crude fat and crude fibers,so that the distiller's grain has richer nutritional ingredients and can be better digested and absorbed by animals, consequently, not only is the problem of waste distiller's grain solved, but also value in use and economic benefit are created, and the comprehensive utilization of residual starch of the distiller's grain is realized.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of pure grain liquor discarded grains, and in particular relates to a method for preparing high-protein feed by discarded liquor grains. Background technique [0002] my country is a country with a large production of baijiu, and baijiu is an indispensable and important medium in the traditional Chinese social field. Waste grains are an important by-product of liquor production. The main components in the waste grains are residual starch, crude protein, crude cellulose, crude fat, crude vitamins and many trace elements. Due to the large amount of chaff fibers, these are not easy to be digested and absorbed by animals. The water content is high, the acidity is high, and it is easy to spoil and deteriorate. It is not suitable for long-term storage and transportation. Therefore, many wastes can only be piled up on the spot. The air and the nearby surface water cause serious pollution, which...
