[0002] In the field of bio-agriculture, a fermentation tank is widely used as an important auxiliary device in the process of microbial fermentation. The main function of the fermentation tank is to provide a precisely controlled environment to promote the growth and metabolism of microorganisms, so as to complete a specific fermentation reaction. In the traditional fermentation process, the growth condition of the microbial flora in the fermentation liquor directly affects the quality and yield of the final product.

[0003] At present, most of the fermentation tanks on the market use the traditional stirring form to stir the fermentation liquor. Although such a stirring method can achieve the stirring effect, it cannot be adaptively adjusted according to the needs of different fermentation stages.

Such a way has a low integration level and does not conform to the concept of intelligent production today. In addition, foam is difficult to avoid at the top of the fermentation liquor during fermentation. Since the liquid level of the fermentation liquor is different each time, the position of the defoaming device needs to be adjusted. The position of the defoaming device cannot be automatically adjusted according to the liquid level, which reduces the fermentation efficiency. SUMMARY

[0023] Compared with the prior art, the present application has the following advantages:

[0024] 1. The rotating shaft drives the stirring assembly to rotate to stir the fermentation liquid, achieving the effect of primary stirring; the rotating shaft rotates to drive the stirring assembly to generate centrifugal force, the gravity end head drives the flow guide pipe to slide through the centrifugal force, and the stirring blades are unfolded to strengthen the stirring of the fermentation liquid, thereby achieving secondary stirring of the fermentation liquid without additional driving; the rotation speed of the rotating shaft is adjusted to control the centrifugal force, thereby controlling the secondary stirring effect.

[0025] 2. By utilizing the gravity end in conjunction with the anti-clogging vibration component, the gravity end and the protrusion exert pressure, causing the stirring blades to oscillate back and forth, further enhancing the disturbance of the fermentation broth and achieving the purpose of three-stage stirring.

[0027] 4. The rotating shaft can not only drive the defoamer and stirring components, but also adjust the state of the stirring blades on the stirring components by adjusting the rotation speed of the shaft. With the anti-clogging vibration component, the stirring blades can also be made to oscillate back and forth.
