Description

Technical Field

[0001] This utility model relates to the field of feed fermentation technology, and more specifically, to a feed fermentation device for rabbit farming. Background Technology

[0002] In rabbit farming, feed fermentation technology is an important feed processing technology. Through the action of microorganisms, it transforms indigestible feed ingredients into forms that are easier for animals to absorb and utilize. Specifically, the microorganisms in fermented feed can break down large molecules in the feed, such as cellulose and hemicellulose, into smaller molecules, such as amino acids and oligosaccharides, which are easier for rabbits to absorb and utilize.

[0003] In existing technologies, fermentation tanks are commonly used for fermentation. For example, the patent with publication number CN218321422U discloses a biological feed fermentation device for rabbit farming. Specifically, it uses a tank as the fermentation container and further heats the fermenting material by stirring the agitator blades. The agitator blades are located in the middle of the fermentation tank, which is conducive to uniform heating of the fermenting material. However, the agitator blades are hollow and require the introduction of a heat exchange medium for heating. The heat exchange medium needs to be pushed out by the subsequent introduction of medium, resulting in poor heat exchange effect and the risk of leakage of the heat exchange medium during stirring.

[0004] Based on the above description, there is an urgent need for a feed fermentation device for rabbit farming that can efficiently and uniformly exchange heat. Utility Model Content

[0005] The purpose of this utility model is to provide a feed fermentation device for rabbit farming, which aims to solve the technical problems of existing fermentation tanks using stirring fan blades for stirring, and the fact that the heat exchange medium cannot be quickly discharged after heat exchange due to the cavity inside the stirring fan blades.
