The main material of the fermentation tank is a full stainless steel 316L tank with no dead corners inside the tank; it is equipped with special sampling, discharge valves, and transfer pipes for the fermentation tank. The 12V safety light with temperature uses a wide-angle tank liquid level observation mirror, PH, DO, and all welds are solid, neat, and beautiful, including defoaming, liquid level interface, inoculation port, feeding port, and multiple spare ports.

300L fermentation tank: design pressure 0.3Mpa; jacket: design pressure 0.3Mpa jacket: Mpa, adopts optimized flow diversion design to improve the exchange efficiency and temperature uniformity in the tank

300L fermentation tank body function: John Crane mechanical seal, air inlet sterilization filter, exhaust condenser, air inlet system with air distributor, flame inoculation port (also air inlet and cleaning port), feed port, sampling port, feed port; five electrodes for automatic control parameters are PH electrode, DO electrode, defoaming electrode and temperature electrode; four peristaltic pumps automatically control to add acid/alkali/enemy/culture agent respectively;

Motor: AC motor dedicated to fermentation tank to ensure that the motor can operate in harsh environment;

Ventilation: according to process requirements, deep ventilation and rotation are adopted The sub-flow meter adjusts the gas flow, and the air distributor in the tank evenly distributes the gas; the sterilizing filter (Dominic) with an accuracy of 0.2μM has a device to prevent material backflow, which ensures safety and greatly extends the service life;

Stirring system: SEW AC motor, Fuji inverter, adopts upper drive direct coupling mechanical stirring mechanical stirring method, simple structure and stable operation

Stirring form of 300-liter fermentation tank: straight blade stirring paddle (secondary), inclined blade stirring paddle (first level), mechanical pressure defoaming paddle (first level), four material baffles;

Temperature control: electric heating, water cooling, circulating pump circulation temperature control, air self-escape function, water cut-off, over-temperature protection function, good heat exchange efficiency; intelligent module control not only ensures the rapidity of temperature control, but also achieves energy saving.
