  • Fermentation device comprising a coupled substrate and sediment transport mechanism and method for operating the fermentation device
    Patent number: 8241869
    Abstract: A fermentation device for biological degradation of substrate containing organic material and for recovery of biogas produced by degradation has an elongate closed container having a first end and a second end opposite the first end. The first end has an inlet opening for untreated substrate and the second end has at least one removal opening for treated substrate. The container has at least one removal opening for biogas. The container has several reaction cells provided with individually driven mixing units. The mixing units have mixing unit shafts positioned transversely to a longitudinal extension of the container and mixing impellers mounted on the mixing unit shafts and driven on a circular path. The mixing unit shafts are arranged at axial spacings smaller than a diameter of the mixing units so that the mixing impellers when the mixing unit shafts rotate pass trough an overlap range.
