METHOD AND DEVICE FOR ANAEROBICALLY FERMENTING OF ORGANIC MATERIAL

摘要

Method for anaerobically fermenting biodegradable organic material, whereby this material is mixed with a quantity of already fermented material as an inoculum for the active anaerobic fermentation and this mixture is introduced at the top into a fermentation chamber ( 1 A) in which a fermenting mass is situated, which, while being fermented, moves from an inlet ( 6 A) situated at the top towards an outlet ( 8 ) situated at the bottom. Before the mixture is added to the fermenting mass, it is expanded beforehand until its density approximately coincides with the density of the already present fermenting mass at the beginning of this downward movement.
