[0002] Fermentation tank refers to the device used for microbial fermentation in industry, and its main body is generally a main type cylinder made of stainless steel plate. Some fermentation tanks need to be provided with liquid inlets to supplement carbon sources (glucose, starch), nitrogen sources (peptone, urea), inorganic salts (phosphate) and other liquid nutrients by feeding to maintain the growth environment of microorganisms and meet the metabolic needs of microorganisms.

[0003] Some existing fermentation tanks mostly add nutrients by manual preparation and manual addition when adding nutrient liquid. At this time, the liquid inlet of the fermentation tank is in an open state, and air in the environment will enter the fermentation tank through the liquid inlet along with the liquid. Since some anaerobic fermentation needs to avoid the entry of oxygen, the sealing performance of the liquid inlet is insufficient, which can cause air to enter and change the oxygen concentration in the fermentation tank, affect the growth of microorganisms, and further affect the fermentation effect and efficiency.
