Preparation method of special drying agent for fermented bean meal

Abstract

The present invention relates to a preparation method of a special drying agent for fermented bean meal, and belongs to the technical field of drying agent preparation. According to the present invention, a ceramic capable of transmitting far infrared rays is prepared, the ceramic, cow dung and a biogas liquid are subjected to mixing fermentation and micro-corrosion treatment, the fermentation broth is immersed in the internal pores and is frozen through liquid nitrogen, breaking is performed by using an ice cracking effect, crushing is performed through a stone breaker to obtain modified ceramic particles, and the ceramic particles and hydrophilic-group-rich plants and fruits are subjected to compound modification under the effect of microorganisms to prepare the special drying agent for fermented bean meal. According to the present invention, the special drying agent for fermented bean meal has the good drying effect, wherein the water content in the dried fermented bean meal is less than 10%; the drying agent cannot destroy the biological activity and the nutritive value of the fermented bean meal, such that the number of the viable organisms in the dried fermented bean meal achieves 5.4*10<9>-7.2*10<10>cfu/g; and the operation process is simple, the cost is low, and the method is suitable for the promotion of the industrial production.

Description

technical field [0001] The invention relates to a method for preparing a special desiccant for fermented soybean meal, and belongs to the technical field of desiccant preparation. Background technique [0002] Fermented soybean meal, also known as bio-peptide, bio-soybean meal, bioactive small peptide, soybean peptide, has become the best substitute for fish meal. This product is a combination of modern bioengineering fermentation strain technology and traditional Chinese solid fermentation technology, using high-quality soybean meal as the main raw material, inoculating microorganisms, and eliminating the anti-nutritional factors in soybean meal to the greatest extent through microbial fermentation, effectively degrading soybeans Protein is a high-quality small peptide protein source, and can produce active substances such as probiotics, oligopeptides, glutamic acid, lactic acid, and vitamins. It has the effects of improving palatability, improving digestion and absorption ...

Problems solved by technology

[0005] The technical problem to be solved by the present invention: in the traditional drying method of fermented soybean meal, the high-temperature drying method will cause the fermented soybean meal to lose its unique biological activity and nutrition after fermentation, while the low-temperature drying method will increase the production cost, which is not conducive to scale In order to solve the problem of chemical production, the present invention firstly prepares ceramics that can emit far-infrared rays, and then mixes it with cow dung and biogas liquid to ferment and carry out micro-rot treatment, so that the fermented liquid is immersed in its internal pores, and the fermented liquid is frozen by liquid nitrogen freezing , use the ice splitting effect to break it, and then crush it with a stone crusher to obtain modified ceramic particles, and then compound and modify the ceramic particles and plants and fruits rich in hydrophilic groups under the action of microorganisms to increase the hydrophilicity of the surface of the ceramic particles. The number of water groups, so that it has the function of water absorption and drying, combined with the far-infrared characteristics of ceramics and the infrared rays emitted by plants to dry soybean meal
