Load Proportion 65-80% of total volume, 70% optimum
Vessel Material Part glass body and stainless steel lid and bottom
The high ratio: 2:1
Mixing method: Magnetic Drive from bottom, without mechanical seal
Sterilization method: Automatic sterilization in situ
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
Stirring system
Mechanical sealing system: high-powered stirring oar, antifoam oar; AC electrical machine: infinite speed variation; rpm in the fermenter: 70~1000rpm±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
