Biomass material conveying device for fermenter has second conveyor by which biomass can be fed, bypassing chopping-up machine

摘要

The conveying device conveys biomass material into e.g. a fermenter (10, 11), and may have a conveyor (5) in the form of a screw conveyor. It also has a second conveyor (9), through which the biomass can be fed so that it bypasses the chopping-up machine (8), after which it is fed back into the biomass material coming from the chopping-up machine.
