Problems solved by technology

[0005] Rapeseed meal (rapeseed cake) is a high-protein feed with great utilization value, containing 35%-40% protein, 10.46-12.55kj / kg digestible energy, 0.61% calcium, 0.95% phosphorus, and iron, copper, Manganese, selenium and other trace elements and multivitamins, but because of the anti-nutritional factors such as sinaprin, erucic acid, phytic acid and tannin, its use and dosage are greatly reduced

Abstract

The invention discloses a method for producing a biological protein feed through mixed solid fermentation of yeast production wastewater and rapeseed meal by using a composite strain. The method comprises the following steps: mixing rapeseed meal used as a raw material with yeast wastewater used as an auxiliary material, and adjusting the water content of the above obtained mixed material to 35-45%; adding the composite strain accounting for 0.2-0.5% of the mass of the mixed material, and fermenting the mixed material at 20-55DEG C for 40-75h; and drying the fermented material in a 50-75DEG C fluidized bed, crushing the dried fermented material, and packaging the crushed fermented material to obtain the biological protein feed. Fermentation of the yeast wastewater and the rapeseed meal is initiated at home. The method has the advantages of simple process, easy operation, short production period, low production cost, and good product quality. The yeast production byproduct fermentation concentrate water is changed into valuables from wastes, so the carbohydrate source waste condition in China is solved, and promotion of the environmental protection industry in China is benefited.

Description

technical field [0001] The invention specifically relates to a method for producing biological protein feed through mixed solid fermentation of yeast production wastewater and rapeseed meal by using compound strains. Background technique [0002] Yeast production mainly uses molasses as raw material, mainly sugarcane molasses and beet molasses, and the clear liquid produced by yeast production mainly comes from molasses itself. Molasses is a by-product of sugar production in sugar factories, which is rich in sugar. After the available sugar in molasses is fermented and utilized by yeast, the remaining substances that are not used by yeast and the metabolites produced by yeast metabolism will eventually be discharged with the fermentation separation liquid . Therefore, yeast wastewater is rich in inorganic trace elements such as nitrogen, phosphorus, potassium, calcium, and iron, monosaccharides, yeast proteins, rich proteases, and macromolecular organic compounds such as ca...
