Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing device technology, specifically to a mixing device for a feed fermentation machine. Background Technology
[0002] Pig feed is typically composed of protein feed, energy feed, roughage, green fodder, silage, mineral feed, and feed additives. Fermentation is a crucial step in pig feed production, significantly improving palatability. Microbial activity during fermentation produces microbial proteins, bioactive peptides, and amino acids, enhancing the pig's immunity and feed utilization. Fermentation usually requires a fermentation device. Therefore, it is essential to maintain thorough mixing between the feed and the liquid within the fermentation device during the fermentation process.
[0003] For example, Chinese patent CN221759842U discloses a stirring device for a feed fermentation machine. Its structure includes a fermentation tank, a feed hopper, a discharge end, a motor, and a stirring device. The beneficial effects of this utility model are: while the feed is stirred by the crushing frame, the feed is cut and crushed by the saw blades on both sides of the crushing frame. At the same time, the centrifugal force generated by the rotation between the upper and lower rings drives the rotating part to rotate, thereby stirring the feed in the fermentation tank. This allows the pig feed to be fined and thoroughly and evenly stirred, increasing the fermentation effect of the feed and avoiding the situation where the feed is not sufficiently stirred, resulting in a low degree of fermentation.
[0004] Although the aforementioned patent enables pig feed to be finely mixed and thoroughly, thus increasing the fermentation effect and preventing insufficient fermentation due to inadequate mixing, the fermentation agent liquid inside the fermentation device is prone to uneven mixing when it is mixed with the pig feed through the mixing device, reducing its practicality.

[0043] When pig feed needs to be fermented, the pig feed is poured into the fermentation tank 2 through the feed cylinder 3. Then, the centrifugal pump 52 is started to transport the fermentation agent liquid inside the liquid tank 51 through the pipeline to the inside of the annular hollow liquid outlet plate 55.
