When the utility model works, the biological material to be fermented is put into a culture tank, and a proper amount of sterile fermentation medium is injected into the culture tank. Then the stirring motor is started to enable the stirring paddle to uniformly mix and oxidize the biological material and the culture medium. Meanwhile, the temperature control module is started, and the working state of the heating belt is regulated according to the temperature signal detected by the temperature sensor, so that the inside of the culture tank is kept constant and the temperature is suitable for biological fermentation. When the fermentation process is required to be monitored or sampled, part of liquid in the liquid outlet pipe can be led into the sampling bottle by operating the sampling valve.
