Double mechanical seal Production fermentation system 300 liter
The bottom agitation bioreactor
Fermenter body
The size of fermenter takes in general use type as basis and The main material of the fermenter is made by 316L stainless 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: 1:2.5
5 liter fermenter Work volumes ranging from 2-3.5 Liters
50 liter fermenter Work volumes ranging from 20-35 Liters
500 liter fermenter Work volumes ranging from 200-500 Liters
Sterilization method
Auto sterilization
Stirring system
Mechanical sealing system at the top of the fermenter; high-powered stirring oar, antifoam oar; AC electrical machine(SEW): infinite speed variation;rpm in the 500L germ fermenter: 70~400rpm±1%rpm;, 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℃)~70℃±0.1℃,temperature probe(imported)
pH detection and control
2.00-12.00±0.05pH, autocontrol by adding acid and base, pH sensor (Hamilton /Mettler, Switzerland) and shielding lead (Hamilton /Mettler, Switzerland).
DO detection and control
0-150±3% displaying precision 0.1%, sensor (Hamilton /Mettler, Switzerland) and shielding lead(Hamilton /Mettler, Switzerland)
Feed control
fermenter uses peristaltic pump (Longer) to add meterials
Antifoam control
Tested by sencor and added antifoamer by peristaltic pump
