A container ( 1 ) for the fermentative production of biogas from organic substrates, which container comprises an axial stirrer ( 9 ), one or several inlet devices ( 2 ) for filling the container ( 1 ), one or several outlet devices ( 3, 4 ) for emptying the container ( 1 ) and withdrawing a fermentation residue, an external conduit ( 5 ) for supplying a fermentation mixture into a closed circular pipeline ( 7 ) with several outlets ( 8 ) for spraying on the surface ( 14 ) of the fermentation mixture, with the sprayed fermentation mixture optionally coming from the lower half of the container ( 1 ), a device ( 11 ) for withdrawing the biogas produced and an apparatus ( 10 ) for controlling the temperature of the fermentation mixture; a process for the fermentative production of biogas from an organic substrate, a process for suppressing foam formation during the fermentative production of biogas, and a process for the improved conversion of oils and fats in organic substrates during the fermentative production of biogas, which can be carried out in a container ( 1 ). |
