To achieve the goal of stable and high yield.

The working principle of the utility model is:

1. Sterilization: Before the fermentation starts, the system must be sterilized first, and the manual valves are opened in sequence according to the sterilization process, and steam is introduced to sterilize the feeding device consisting of feeding tanks, valves and pipelines;

2. Feeding: When feeding, close the pneumatic diaphragm valve 8 of the discharge port, open the pneumatic diaphragm valve 6 of the feed port, and the nutrient solution enters the quantitative feed tank 12 from the feed pipe through the feed port. When the feed liquid is added When it is full, the upper float (or upper electrode) sends a signal to close the pneumatic diaphragm valve 6 at the feed port;

3. Feeding: Open the pneumatic diaphragm valve 8 at the discharge port, and the feed liquid is discharged into the fermenter 13. When the liquid level drops to a certain height, the lower float (or lower electrode) sends a signal to close the pneumatic diaphragm at the discharge port Valve 8, open the pneumatic diaphragm valve 6 of the feeding port, and repeat the feeding process for the next time.

4. The opening of the manual valve 11 can be determined according to the pressure difference between the top of the quantitative feeding tank and the fermenter, so as to ensure a stable feeding flow.
