DISPOSITIVO DE FERMENTACAO

摘要

The fermentation device for the biodegradation of organic material and for obtaining the biogas produced in the degradation has a closed container with an introduction orifice (2) for fresh material and inoculation material and discharge openings (4, 7) for the degradation products, as well as a stirring device (3) for mixing the fermentation material. The stirring device consists of stirring blades (18) which are moved in a circle and are preferably driven individually. Also provided are scrapers (12) with which substances (11) which have been deposited on the base of the container are intermittently conveyed to a discharge apparatus (7). A flow-through system (5, 6) for a heating medium is provided on the side walls and is divided where appropriate into a plurality of heating circuits in order to vary the temperature on different sectors of the heating surface.
