[0002] The fermentation device of multi-microbial mixed feed processing is the key equipment in the field of feed production, which utilizes the metabolic activity of microorganisms under suitable conditions to convert multiple raw materials into nutrient-rich and easily digestible feed. The fermentation device of multi-microbial mixed feed processing typically includes the following main parts: fermentation tank, stirring system, control system, etc. During the fermentation process, multiple microorganisms utilize the nutrients in the fermentation broth for metabolic activity in the fermentation tank. The stirring system ensures uniform mixing of the fermentation broth, and the microorganisms grow and metabolize under suitable conditions to convert the raw materials into nutrient-rich feed.

[0003] The existing fermentation device for feed processing can only deliver oxygen-rich air to the upper surface of the feed when supplementing oxygen in the fermentation tank, resulting in insufficient oxygen supply to the interior of the feed and poor use effect.

The fermentation tank is installed on a support, and the top cover is installed on the top of the fermentation tank. A gas guide pipe is installed in the middle of the bottom of the fermentation tank, and five groups of gas branch pipes are symmetrically installed at both ends of the gas guide pipe. An installation housing is installed in the middle of the bottom of the fermentation tank. It can accelerate the mixing and fusion of feed and fermentation agent. The fan works to deliver the oxygen-rich air heated by the heating wire from the outside to the inside of the feed through the air holes below the gas branch pipes, which can accelerate the fermentation speed of the feed.

However, during fermentation, although it can supplement oxygen inside, it cannot guarantee the gas balance inside the fermentation tank, and cannot maintain the gas balance inside the fermentation tank, resulting in that microorganisms cannot grow and metabolize under optimal temperature conditions.
