Working volume: 2500-4000 liters
Material: 316L stainless steel with material contact to the other 304 stainless steel
Sterilization method: Manual situ sterilization(Optional automatic sterilization procedures)
Control system: Siemens PLC, industrial LCD touch computer control, parameters can be set to store, can be remotely connected to the computer through the USB interface, the data
Working volume 45 to 80 liters and The main material of the fermenter is made by 316Lstainless steel. The design pressure: P(inside)= 0.3Mpa, P(interlayer)= 0.3Mpa, The polishing precision: Ra0.4~0.6, the ratio between diameter and height: 1:2.3
Stirring system
Mechanical sealing system at the top of the fermenter; high-powered stirring oar, antifoam oar; AC electrical machine: infinite speed variation; rpm in the fermenter: 70~600rpm±1%,The height of the stirring oar can be adjusted, too.
Temperature detection and control
Heat by thermostatic water tank and circulate by circulating pump(Grundfos, Denmark), autocontrol (cooling water+5°C)~65°C±0.1°C,temperature probe(US)
pH detection and control
2.00-12.00±0.05pH, autocontrol by adding acid and base, pH sensor (Mettler, Switzerland) and shielding lead (Mettler, Switzerland). fermenter is autocontrolled with peristaltic pump
DO detection and control
0-150±3% displaying precision 0.1%, sensor (Mettler, Switzerland) and shielding lead(Mettler, Switzerland)
Feed control
fermenter uses peristaltic pump (Longer) to add meterials
Antifoam control
Tested by sencor and added antifoamer by peristaltic pump
Intake control (air) :manual control rotameter
pressure detection and control
Pressure Control: Pressure meter and digital display and digital remote control, pressure control
