1. The stirring and ventilation device in the fermentation tank equipment should be able to finely disperse and disperse the bubbles, fully mix the gas-liquid, ensure the necessary dissolved oxygen in the fermentation liquid, improve the utilization rate of oxygen, and have sufficient cooling area to discharge the metabolic heat of microorganisms. The temperature required at different stages of the fermentation process should be controlled to minimize dead corners, make cleaning and sterilization convenient, and avoid bacterial contamination. The sealing must be tight to minimize leakage. The self-priming fermentation tank is a type of fermentation tank that inhales air by itself during the stirring process.

2. No need to configure air compressors or blowers, widely used in industries such as pharmaceuticals, acetic acid, yeast, etc. Statorless rotary wing self-priming fermentation tank with stator self-priming fermentation tank overflow spray type self-priming fermentation tank spray self-priming fermentation tank single-layer overflow spray reactor principle: using the jet flow formed during liquid overflow, under the action of the liquid surface layer.

3. Make the gas boundary layer near the liquid surface have a certain movement speed, thereby forming gas flow and self suction. Features: Simple structure, eliminating complex air compressors and their ancillary equipment, low power consumption, high productivity, high dissolved oxygen rate, and good conveying effect of fermentation broth
