Air volume is the volume of air that passes through the fermentation liquid in one minute than the volume of the fermentation liquid with the fermenter sub-sanitized filtration device. Air filtration device configured in front of each fermenter.
Mechanical stirring fermenter of the use of mechanical agitators, so that the air and the fermentation solution is fully mixed to promote the dissolution of oxygen in the fermentation solution to ensure that the supply of microbial growth and reproduction, the oxygen needed for fermentation, fermentation equipment in the important, widely used equipment, is the heart of the fermentation industry, is the connection between the raw materials and the product of the bridge.

Precautions:
1. You must make sure that all individual pieces of equipment in the fermenter can operate properly when using this system.
2. When sterilizing the filter, the steam pressure flowing through the air filter must not exceed 0.17MPa, otherwise the filter element will be damaged and lose its filtering ability.
3, in the fermentation process should ensure that the tank pressure does not exceed 0.17MPa.
4, in the process of real disinfection, the jacket through the steam preheating, you must control the inlet steam pressure in the working pressure of the equipment within the range (should not exceed 0.2MPa), or it will cause damage to the fermenter.
5, in the empty elimination and real elimination, must exhaust the fermenter jacket residual water. Otherwise, it may cause the fermenter cylinder to be flattened, resulting in damage to the equipment; in the real elimination, it will also cause too much condensate resulting in dilution of the culture liquid, which can not meet the process requirements.
6, in the empty elimination, real elimination after the end of the cooling process, it is strictly prohibited to produce negative pressure in the fermenter, so as not to cause contamination, or even damage to the equipment.
