Method and device for the anaerobic fermentation of organic material

摘要

Method for the anaerobic fermentation of organic material, whereby the organic material to be fermented is put in a fermentation tank (1) together with an inoculant and moves or is moved from an inlet (6) of the fermentation tank (1) to an outlet (9) thereof, whereby the fermented material is removed from the tank (1) via the outlet (9), characterized in that a fraction of the fermenting material which is situated between the inlet (6) and the outlet (9) is removed from the fermentation tank (1) via a return opening (12) and is used as an inoculant, while the fermenting material between the return opening (12) and the outlet (9) is still after-fermented for a certain while before it is removed from the fermentation tank (1) via the outlet (9).
