[0002] Microbial fermentation refers to the process of using microorganisms to convert raw materials into products needed by humans through specific metabolic pathways under suitable conditions. The level of microbial fermentation production mainly depends on the genetic characteristics of the strain itself and the culture conditions.

[0003] Usually, during the growth of microorganisms, a large amount of metabolites or secondary metabolites are discharged, and these metabolites have a certain impact on the continued growth of microorganisms. At the same time, microorganisms need oxygen and other gases during growth, so during the cultivation process, continuous stirring is required to keep the materials in the fermentation tank mixed and the proportions and temperatures of the various substances consistent.

[0004] While the microbial fermentation tank is in use, air can be introduced into the fermentation tank, but the air can only be introduced into the fixed layer area of the fermentation tank, resulting in slow contact of microorganisms in other layers of the fermentation tank, causing poor microbial fermentation effect. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the utility model provides a biological science microbial fermentation tank, which solves the problem that air can only be introduced into the fixed layer area of the fermentation tank, resulting in slow fermentation contact of microorganisms in other layers of the fermentation tank.

[0011] Preferably, valves are provided on the surfaces of the feed pipe and the discharge pipe. Beneficial effects

[0012] The utility model provides a biological science microbial fermentation tank. Compared with the existing technology, it has the following advantages:

[0013] (1) The utility model extracts oxygen by controlling the air inlet pipe on the vacuum pump, discharges the oxygen to the rotating pipe through the air outlet pipe, and makes the rotating pipe enter the jet pipe through the vent pipe, so that the multiple air outlets on the jet pipe spray oxygen into the layered areas at different heights. At the same time, the motor drives the rotating rod to rotate, and the rotating rod drives the rotating pipe to rotate through the gear, so that the rotating pipe drives the jet pipe to rotate in a circular manner to spray oxygen, thereby evenly distributing the oxygen in different areas, making the oxygen distribution more uniform and ensuring the effect of microbial fermentation.

[0014] (2) The utility model drives the auger blades to rotate through the rotating tube. The rotation of the auger blades pushes the culture medium below to the top, thereby continuously pushing the culture medium below to the top, which can effectively allow the microorganisms to fully contact with oxygen.
