Laboratory bioreactor BLBIO series

for microbial fermentationcell cultivationsterilizable in-situ

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
