Biological fermentation bran and processing equipment thereof

Abstract

The invention relates to the technical field of biological fermentation, and discloses biological fermentation bran and processing equipment thereof. The processing method comprises the steps of: carrying out impurity removal on a bran raw material, smashing the bran raw material through a plant smashing machine after the impurity removal, and enabling the smashed bran raw material to pass through a 40-mesh sieve and then bagged for use; taking and mixing the bran sieved in the S1 and standard flour to be prepared into bran powder, adding water to carry even mixing, and keeping the humidity at 55-60%; adding 0.4% of selected dry yeast into the wetted bran powder in the S2, uniformly stirring, putting the mixture into a constant-temperature box after uniformly stirring, and culturing for 1-3 hours to prepare a mother strain; and adding water into the sieved and bagged bran in the S1, uniformly stirring, and determining humidity until water drops drop from the hand seam when the bran is held by a hand or until the humidity is 55-60% detected by an instrument. According to the biological fermentation bran and the processing equipment thereof, the microorganisms are utilized to ferment the bran to decompose nutrient substances in the bran in advance, the absorption efficiency of the nutrient substances in the bran during feeding is improved, and the fermented bran is not likely to scatter in the feeding process so as to avoid waste of the bran.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to biologically fermented bran and processing equipment thereof. Background technique [0002] From wheat to flour, it needs to go through the following procedures. First, the wheat should be cleaned. This process includes removing dirt, dust, garbage, iron filings, moldy wheat, and rotten wheat. Secondly, it needs to adjust the moisture content of the wheat grains. After the process, the wheat is sent to the mill for grinding, and the milled mixed coarse powder falls into the screening mechanism to distinguish the flour and wheat bran. In the existing flour mill, the wheat bran is directly output as a by-product , used as feed, it has the advantages of wide source, low cost, easy processing and so on. [0003] At present, in the breeding industry, bran has been used as primary raw material for a long time and directly added to other feeds to feed livestock and poul...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a biologically fermented bran and its processing equipment, which uses microorganisms to ferment the bran to decompose the nutrients in the bran in advance, and improve the absorption efficiency of the nutrients in the bran during feeding, and It is not easy to scatter during the feeding process to cause waste of bran, which solves the problem that bran is directly added to other feeds to feed livestock and poultry. Nutrients such as crude protein, crude fiber and trace elements in bran are difficult to be fully absorbed by the body of livestock and poultry. To achieve the expected nutritional value, the utilization value of bran is reduced. In addition, the bran particle size is small and powdery. It is easy to fall off or stick to the trough when it is directly mixed with other feeds, so it cannot be eaten by livestock and poultry.
