The transmission box 7 is fixedly installed in the middle of the upper outer surface of the fermenter 1, and the motor 10 is fixedly installed on one side of the outer surface of the transmission box 7.

[0027] The upper part of the rotating shaft 8 extends into the transmission box 7. Both the worm 18 and the worm wheel 17 are located inside the transmission box 7. The worm 18 is located on one side of the outer surface of the worm wheel 17. A coupling is provided between the worm 18 and the motor 10. One end of the outer surface of the worm 18 is fixedly connected to one end of the outer surface of the output shaft of the motor 10 via the coupling. A sealed bearing is provided between the worm 18 and the transmission box 7, and the worm 18 is rotatably connected to the transmission box 7 via the sealed bearing. One side of the outer surface of the worm 18 meshes with one side of the outer surface of the worm wheel 17. The worm wheel 17 is fixedly installed on the outer wall of the upper part of the rotating shaft 8. Couplings are provided between the rotating shaft 8 and the transmission box 7 and the fermentation tank 1. A sealed bearing is used to rotatably connect the rotating shaft 8 to the transmission box 7 and the fermentation tank 1. The air inlet pipe 14 is fixedly installed on the upper outer surface of the rotating shaft 8, and the pneumatic rotary joint 15 is fixedly installed on the upper outer surface of the air inlet pipe 14. The air outlet 16 is opened inside the rotating shaft 8, and the inner cavity of the air inlet pipe 14 is connected to the air outlet 16.
