NOVELTY - The fermenter (10) for production of biogas from organic material, comprises fermentation chamber (11) comprising a round base surface for receiving fermenter material, a filler facility (12) arranged in the rim region of the chamber for substrate to be fermented, an unpressurized gas storage (13) arranged above the chamber and having a gas takeoff facility (14), a stirrer (15), a settling chamber comprising an overflow edge, and a pump unit introduced into the settling chamber for continuous/stepwise takeoff of fermenter material from the fermentation chamber.    USE - For the production of biogas from organic material.    ADVANTAGE - The fermenter is cost effective and ensures high yield of biogas from organic material.    DETAILED DESCRIPTION - The fermenter (10) for production of biogas from organic material, comprises fermentation chamber (11) comprising a round base surface for receiving fermenter material, a filler facility (12) arranged in the rim region of the chamber for substrate to be fermented, an unpressurized gas storage (13) arranged above the chamber and having a gas takeoff facility (14), a stirrer (15), a settling chamber comprising an overflow edge, and a pump unit introduced into the settling chamber for continuous/stepwise takeoff of fermenter material from the fermentation chamber. The fermentation chamber is implemented in the form of a ring channel. The settling chamber in its lower region exhibits a fixed bed reactor containing fermenter material. A pump mechanism is intended below the fixed bed reactor for removing the fully fermented residual material. The settling chamber is arranged in the center of the fermentation chamber. The stirrer is arranged in the rim region of the fermentation chamber and consists of two stirrers. The stirrer is arranged in such way that it takes off the material from the surface of the fermenting mass and presses the material towards diagonal direction. A material stream is generated in the area of the sigmoid stirrer and passes through the fermentation chamber. The stirrer is adjusted with respect to its angle to the horizontal axis and/or to the vertical axis. One of the stirrers is formed in diagonally upward and downward manner. Both the stirrers exhibit a point respectively at different sides at the vertical axis of the fermentation chamber. The fermenter exhibits a tempering mechanism for the substrate and the temperature of the fermenter material in the chamber is adjusted through the tempering mechanism over the filler facility. The filter facility is arranged between the stirrers. A compressed air mechanism is intended in the settling chamber, for preventing the formation of a floating cover at the overflow edge. The gas storage is limited by a foil, which is stretched over the top opening of the fermentation chamber. The fermenter exhibits a roof structure, which is arranged over the gas storage. The gas storage and/or settling chamber or an electrical mechanism are intended in the region of the fermentation chamber. The fermentation chamber, the gas storage and/or the settling chamber are implemented as a faraday cage. The fermenter exhibits a settling channel that is arranged in the base region of the fermentation chamber.
