What is the difference between anaerobic fermentation equipment and ventilated fermentation equipment in structure?

1. Aerated fermentation equipment: It is required that the aeration flow is large and the stirring speed is high. There are baffles, upper, lower and middle aeration pipes, oxygen aeration pipes and other structures in the tank, which only increase the dissolved oxygen in the culture process.

Anaerobic fermentation equipment: there can be no dissolved oxygen, so there is no need for high-speed stirring, large amount of ventilation, nitrogen ventilation, baffles and other structures to increase dissolved oxygen in the fermentation tank.

2. Advantages of aeration fermentation equipment: strong applicability, ensuring the supply of oxygen, introducing sterile oxygen and reducing the pollution of miscellaneous bacteria. Disadvantages: high cost.

3. Advantages of anaerobic fermentation equipment: no stirring device, using the density difference of culture solution, saving energy by liquid circulation and reducing equipment cost. Disadvantages: not suitable for use in high viscosity or medium containing a lot of solids.
