Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, and particularly relates to an experimental mechanical stirring fermentation tank. Background Art

[0002] In the laboratory, in order to provide a stable, homogeneous and controllable culture environment for microorganisms to improve the fermentation efficiency of microorganisms, staff usually use an experimental mechanical stirring fermentation tank to ferment microorganisms. The existing experimental mechanical stirring fermentation tank usually consists of a fermentation tank body, a stirring mechanism and a feeding seat.

[0003] For example: The utility model with the application number CN202321521500.0 discloses a stirring fermentation tank, which specifically includes a main body mechanism, an exhaust mechanism and a stirring mechanism. The exhaust mechanism is arranged on the upper surface of the main body mechanism, and the stirring mechanism is arranged inside the main body mechanism. The main body mechanism includes a fermentation tank, a feeding port, a cover plate, a pressure gauge, a thermometer, a fixing rod, a threaded block and a discharge port. The feeding port is fixedly connected to the upper surface of the fermentation tank, the cover plate is movably connected to the upper surface of the feeding port, the pressure gauge is fixedly connected to the upper surface of the fermentation tank, the thermometer is fixedly connected to the front surface of the fermentation tank, and the fixing rod is fixedly connected to the lower surface of the fermentation tank.

The materials are not easily contaminated, and air is prevented from entering the fermentation tank to affect the fermentation quality.

[0004] However, for the current traditional experimental mechanical stirring fermentation tank, when fermenting microorganisms, the raw materials for cultivating microorganisms are usually directly added into the fermentation tank through the feeding port. However, the feeding speed of the raw materials directly added into the fermentation tank is relatively fast, which easily causes the raw materials to directly fall to the bottom of the tank or accumulate in a certain local area, affecting the fermentation effect of microorganisms and being inconvenient to use.
