▎Equipment Applications

Fermentation tanks are widely used in the fermentation of materials in industries such as biology, chemicals, traditional Chinese medicine, veterinary drugs, pesticides, and organic fertilizers.

▎Main Technical Parameters

1. Nominal Volume: 50L~100T (customizable).

2. Loading Coefficient: ≥70%.

3. Tank Material: SUS304/316L stainless steel.

4. Surface Finish: Mirror polished inner surface, frosted outer surface.

5. Heating and Cooling Method: Combination of outer jacket/outer half-pipe and inner tube.

6. Tank Interfaces: pH, DO, temperature, inoculation, defoaming, acid replenishment, alkali replenishment, material replenishment, pressure, sight glass light, etc.

7. Structural Forms: Vertical legs, lug supports, skirt support type, meeting different working conditions.

8. Agitation System: Top mechanical agitator, sanitary mechanical seal.

9. Blade Types: Defoaming blade, flat blade, inclined blade, turbine type, etc.

▎Control System

1. The tank is equipped with a temperature-controlled jacket, PID digital control, in-situ sterilization, and temperature control accuracy of ±0.2℃.

2. Temperature control range: 0-150±0.2℃.

3. Sterilization temperature: 100-130℃.

4. Stirring speed: 50-200 rpm (speed determined according to tank size and material requirements).

5. pH control: 2-12±0.02, automatic adjustment by a peristaltic pump for acid and alkali addition, with signal transmission via an imported pH sensor.

6. DO control: 0-100%, DO is linked to the stirring speed control, with signal transmission via a Mettler DO sensor.

7. Foam control: Automatic control and alarm, online monitoring with stainless steel electrodes, automatic addition of defoamer by a peristaltic pump.

8. Air flow: Mass flow meter, automatic adjustment by a pneumatic valve. Inlet air filter, exhaust air filter.

9. Tank configuration: Flame inoculation port, sampling valve, and bottom valve for immediate sterilization.

10. System Control: Touch screen operation interface, Siemens PLC automation control program, realizes online operation of the whole equipment, automatic stirring, sterilization, dissolved oxygen, pH adjustment, temperature adjustment, automatic defoaming, etc.
