Problems solved by technology

At present, fermented feed manufacturers generally use horizontal ribbon mixer or horizontal double-shaft paddle mixer to pre-mix feed materials and bacteria, and then directly transfer them manually or mechanically to cellar, trough or tower. Fermentation, these fermentation methods have two main disadvantages: first, the fermentation time is as long as 72 hours, and the fastest is 36 hours, and the efficiency is very low; second, there are many uncontrollable factors in the fermentation process, such as moldy, excessive fermentation, etc. lead to unstable product quality
Therefore, it is impossible to form industrialized feed fermentation production, which seriously limits the fermentation production of feed

Embodiment 1

[0038] Propagate Bacillus subtilis and Bacillus coagulans in a liquid medium at a ratio of 1:1, and the formula of the medium is as follows: casein peptone 5-10%, salt 0.5-0.8%, sucrose 2.8-3.5%, hydrochloric acid 0.1- 0.5%, water 80-90%. After culturing at 37° C. for 12 hours, the culture liquid containing Bacillus subtilis and Bacillus coagulans was obtained by performing secondary fermentation on the bacterial liquid obtained from the primary fermentation for 24 hours. The above-mentioned culture solution was sprayed into auxiliary materials containing 10% soybean hull powder and 90% diatomaceous earth, and dried at a low temperature of 35° C. for 50 minutes to obtain a microbial premix. The total concentration of Bacillus subtilis and Bacillus coagulans in the auxiliary material in the prepared microbial premix is ​​1*10 8 CFU / g.

[0039] The feed raw material is fermented in a feed fermentation mixer by using the microbial premix to prepare the fermented feed. The spec...

Abstract

The invention relates to the technical field of feed processing and producing and discloses microbial rapid fermentation feed and a preparation method thereof. The preparation method comprises the following steps: feeding feed raw materials and a microbial premix into a feed fermentation mixer for stirring and mixing, wherein the weight ratio of the microbial premix to the feed raw materials is 7.5 to 10kg / t, and controlling the speed of a rotor of the feed fermentation mixer at 25 to 30 revolutions per minute; when the temperature of materials in the feed fermentation mixer is raised to 40 to 50 DEG C, adding the microbial premix again for continuously stirring, wherein at the moment, the weight ratio of the added microbial premix to the feed raw materials is 7.5 to 10kg / t; when the temperature of the materials in the feed fermentation mixer is raised to 50 to 60 DEG C, adding the feed raw materials into the feed fermentation mixer again for continuously stirring; when the temperature of the materials reaches 50 to 60 DEG C again, outputting the materials, and cooling to obtain the feed. The cycle of fermentation for each batch is 3 hours, so that the time is effectively saved; the preparation method has the advantages of simple process, high controllability, extremely-high production efficiency and capability of realizing scale production.

Description

technical field [0001] The invention relates to the technical field of feed processing and application, in particular to a microbial rapid fermented feed and a preparation method thereof. Background technique [0002] Feed fermentation is to mix and stir certain feed materials, water and bacteria, and ferment under certain conditions to make a high-activity biological feed. At present, fermented feed manufacturers generally use horizontal ribbon mixer or horizontal double-shaft paddle mixer to pre-mix feed materials and bacteria, and then directly transfer them manually or mechanically to cellar, trough or tower. Fermentation, these fermentation methods have two main disadvantages: first, the fermentation time is as long as 72 hours, and the fastest is 36 hours, and the efficiency is very low; second, there are many uncontrollable factors in the fermentation process, such as moldy, excessive fermentation, etc. Lead to unstable product quality. Therefore, industrialized fee...
