ABSTRACT:
Disclosed is a bioreactor in which a supporting wall (100) or a retaining mechanism (100) that represents pressure relief for a gas-tightly embodied flap is provided behind the flap (14) used for filling and emptying the bioreactor while percolate is prevented from accumulating between the gas-tight flap and the retaining mechanism. The gas-tightly closable flap, which has a sufficiently large size, makes it easy to fill biomass into the container and remove the remaining biomass following the methanation process. The biomass applies substantial or at least a certain amount of pressure to the retaining system when the container is closed, whereby the flap is relieved of the load and can be embodied in a light and accurately sealing manner. A device (22) for draining percolating juice or percolate is disposed in the floor and/or the walls of the bioreactor between the flap and the retaining system such that percolating juice is prevented from accumulating in the zone between the flap and the retaining system or percolate located there can be pumped off before the flap is opened.
