Use method of wet solid-state fermentation soybean meal, complete feed prepared with wet solid-state fermentation soybean meal and preparation method thereof

Abstract

The invention discloses a use method of wet solid-state fermentation soybean meal, a complete feed prepared with the wet solid-state fermentation soybean meal and a preparation method thereof. The use method of the wet solid-state fermentation soybean meal, i.e. the method for preparing the complete feed with the wet solid-state fermentation soybean meal comprises the following steps of: uniformly mixing 8.0-16.0 parts of undried wet solid-state fermentation soybean meal, 10.0-15.0 parts of bulking soybean flour and 6.0-8.0 parts of soybean meal powder in advance to prepare an intermediate material; adding the intermediate material into other materials prepared according to the formula of the complete feed, and then mixing, thermal refining with steam, granulating, cooling, screening and packaging to prepare the complete feed product. In the complete feed prepared according to the invention, the wet solid-state fermentation soybean meal as well as the soybean meal powder with good fluidity and the bulking soybean flour with better hydrophobicity are adopted and mixed in advance so as to improve the fluidity, and then the mixed wet solid-state fermentation soybean meal, the soybean meal powder and the bulking soybean flour are added into the complete feed according to a certain proportion, therefore, the additional value of the fermentation soybean meal can be improved, the use cost is reduced, and the economic benefit is significantly improved.

Description

technical field [0001] The invention belongs to the technical field of feed raw material processing, and relates to a method for using wet solid-state fermented soybean meal, a full-price feed prepared with wet solid-state fermented soybean meal and a preparation method thereof. Background technique [0002] Fermented soybean meal is a plant protein raw material used in pig feed. It is fermented by yeast, lactic acid bacteria, bacillus and other probiotics in a solid state of 35.0-45.0% moisture, through anaerobic or oxygen-consuming methods, fermented 3- After 5 days, the product was dried and pulverized by hot air flow. The amount of fermented soybean meal used in pig feed is 2.0-8.0%. During the solid-state fermentation process of probiotics, soybean meal can be enzymolyzed by complex enzymes such as protease, pectinase, and amylase produced by probiotics, and macromolecular proteins are degraded. Undesirable oligosaccharides are degraded and consumed by probiotics durin...

Problems solved by technology

[0003] However, since the fermented soybean meal has to be dried by hot air, during the drying process, the high-concentration probiotics, enzyme preparations, and antimicrobial peptides in the solid-state fermented soybean meal lose their activity due to high temperature, which reduces the use value and nutrition of the fermented soybean meal. Added value, the drying process cost of fermented soybean meal is also very high, which is 60% of the net profit of fermented soybean meal. Therefore, if the fermented soybean meal is not dried and used directly, the added value and use value of fermented soybean meal can be greatly increased

[0004] Due to the extremely poor fluidity of wet solid-state fermented soybean meal (with a moisture content of 35.0-45.0%), the compound enzymes produced in the solid-state fermentation process have a certain degradative effect on soybean meal, resulting in poor dispersibility of fermented soybean meal, so it is directly used in full-price feed , easy to mix with flour, glucose, whey powder and other highly hygroscopic raw materials to form a non-dispersible wet mass in an instant, resulting in extremely poor mixing uniformity, which cannot meet the requirement that the coefficient of variation of full-price feed mixing is less than 10%. Therefore, There must be a way to overcome this shortcoming
