Therefore, the fermentation tank needs to be stirred to meet the needs of the microorganisms.

[0003] Based on the above, the existing fermentation tanks still have some shortcomings in use:

[0004] First, the existing stirring teeth are located in the middle of the fermentation tank. When the stirring teeth rotate, the materials in the middle of the fermentation tank can be fully stirred, while the materials on the inner wall surface of the fermentation tank are poorly mixed with the enzyme, which easily leads to uneven temperature in the tank.

[0005] Secondly, fermentation tanks of different models have different sizes, and the stirring teeth are fixedly installed on the surface of the drive shaft. The position of the stirring teeth cannot be moved up and down according to the height of the fermentation tank, resulting in poor mixing effect. Utility Model Content

Under the action of the compression spring elastic force, the outer end surface of the scraper can fit the inner wall of the fermentation tank, and the scraper can stir the material on the inner end surface of the fermentation tank when rotating. The mixing plate cooperates with the scraper to make the material inside the fermentation tank more evenly mixed. The fastening block is slidably mounted inside the vertical slide groove on the surface of the drive shaft, so that the worker can increase the number of sleeves according to the height of the fermentation tank, and move the position of the sleeve up and down, so that the mixing plate can be evenly distributed inside the fermentation tank.
