Abstract

The invention discloses a method for producing protein feed raw materials by carrying out enzymolysis and fermentation on soybean meal. The method comprises the following steps of: culturing a candida utilis fermentation solution, a bacillus subtilis fermentation solution and a lactobacillus acidophilus fermentation solution in liquid, and preparing into a mixed bacterium solution according to the ratio; filling the soybean meal into an explosion cylinder; carrying out steam explosion under a certain condition; mixing exploded materials, the mixed bacterium solution and molasses at the ratio; meanwhile, adding an enzyme preparation to prepare a mixed material; feeding the mixed material into a special modularized solid-state biological raw material continuous fermentation device to carry out enzymolysis and biological fermentation; and drying the fermented materials to obtain the protein feed raw materials. According to the method disclosed by the invention, the exploded materials, the fermented bacterium solution and the enzyme preparation are mixed and then are conveyed into the special modularized solid-state biological raw material continuous fermentation device to carry out the enzymolysis and biological fermentation, so that the requirements of automatic temperature control, humidity control and ventilation amount control are realized; the biological conversion rate is high, the fermentation period is short, the loss is less, the cost is low, and the mechanical and large-scale production can be realized.

Description

technical field [0001] The invention relates to the fermentation of soybean meal, in particular to a method for producing protein feed raw materials by enzymatic hydrolysis and fermentation of soybean meal. Background technique [0002] As an important protein raw material for animal feed, soybean meal is widely used in feed processing, livestock and poultry, and aquaculture industries. However, a large number of anti-nutritional factors contained in soybean meal, such as trypsin inhibitor, soybean antigenic protein, uric acid, lectin, non-starch polysaccharides, etc., affect the digestion and absorption of soybean meal feed by animals. Therefore, it is necessary to effectively remove anti-nutritional factors in soybean meal in production to improve feed utilization; A wide range of low-cost alternatives to high-quality feed protein ingredients. [0003] Microorganisms such as bacillus, yeast, and lactic acid bacteria can be used to directly ferment agricultural and sidel...
