Stirred 10 L – 4 m3

The Fermentation Pilot Plant is equipped with 100 L, 300 L, 1 m3 and 4 m3 vessels which can be used for batch or fed-batch processes. The 300 L and 4 m3 fermentors have dedicated feeding capabilities.

Mixing is applied by speed controlled Rushton turbine stirrers. Dissolved oxygen levels in aerated processes are controlled by computer models. All ingoing and outgoing flows are measured and logged in the process computer. In the near future an 8 m3 bubble column fermentor can handle batch or fed-batch type fermentations.

    Fermentor 10 L

    Four stand-alone 10 l lab fermentors are intended for initial fermentation tests on a small scale and for fermentation tests of feedstocks that have been treated in the bench scale pretreatment unit. The in situ sterilizable fermentors have jackets and Rushton type agitators with speed control, similar to the large main fermentors.

    The four 100 l vessels are often used as inoculum vessels for multiple 300 l and 4 m3 fermentors, but can also be used for executing batch processes. Maximum filling is 70 kg depending on hold-up. Auxiliary substances can be added from extra vessels.

  • BPF ferm 03
    Fermentor 300 L

    The four 300 l vessels can be used for executing batch and fed-batch processes. Maximum filling is 180 kg depending on hold-up. Each vessel is equipped with two dedicated feed vessels. Auxiliary substances can be added from additional vessels. The 300 l fermentors are located in the ATEX (T3) zone.

  • BPF ferm 04 1m3 fermentor
    Fermentor 1 m3

    One 1 m3 vessel is often used as inoculum vessel for the 300 l and 4 m3 fermentors, but can also be used for executing batch processes. Maximum filling is 750 kg depending on hold-up. Auxiliary substances can be added from additional vessels.

  • BPF ferm 05 4m3 fermentor
    Fermentor 4 m3

    One 4 m3 vessel can be used for executing batch and fed-batch processes. Maximum filling is 2,800 kg depending on hold-up. The vessel is equipped with two dedicated feed vessels. One additional vessel is in place for auxiliary substances. The 4 m3 fermentor is located in the ATEX (T3) zone. This scale can also be used for small production batches or production trials. Fermentation usually is followed up by our DSP section.
