Abstract: The device for generating biogas from organic materials, comprises a biogas reactor (10) having a charging chamber (20) for charging with the organic materials, a backflow channel to partial discharge of the materials from the reactor and intermediate chambers (30) arranged in inner area of a capular inner container, a discharge channel, which turn off from the backflow channel (36), a fluid container filled with fluid (76), and a gas discharge pipe connected in the upper area of the reactor and impinged in the inner area of the bioreactor with constant pressure. The device for generating biogas from organic materials, comprises a biogas reactor (10) having a charging chamber (20) for charging with the organic materials, a backflow channel for partial discharge of the materials from the reactor and intermediate chambers (30) arranged at inner area of a capular inner container, a discharge channel, which turn off from the backflow channel (36), a fluid container filled with fluid (76), a gas discharge pipe connected in the upper area of the reactor and impinged in the inner area of the bioreactor with constant pressure, a heat exchanger arranged upstream of the charging chamber for preheating newly supplied organic material by a hot fluid, a mincing unit arranged upstream of the charging chamber, a mixing device arranged for charging the charging chamber, and a gas storage for storing the biogas produced in the reactor. The gas storage partially surrounds the biogas reactor. The charging chambers form an intermediate chamber and the backflow channel forms in this sequence section of a flow path through which flow can pass in only one direction for the organic materials. Two sequential sections form a raising flow path in one case and a falling flow path in the other case. The charging chamber shows an overflow edge by the intermediate chamber of the charging chamber. The intermediate chamber is connected in an area below a charging opening of the backflow channel and above the overflow edge. The cupular inner container is arranged at inner area of the bioreactor. The discharge channel with the backflow channel forms a communicating tube. The cross-section area of the charging chamber is narrowed in an area of the overflow edge. The biogas reactor shows an upper section, which is tapered itself towards the top and the overflow edge extends into the upper section, and a lower section, which is tapered itself towards the bottom. The charging chamber is adapted to mix 1:1 ratio of new organic materials and organic materials discharged from the reactor by the backflow channel. A collecting area is arranged in the lower area of the lower section for sediment and is connectable with the inner room of the biogas reactor and also with the surroundings of the reactor. An end of the gas discharge pipe is placeable in the fluid from the inner area of the biogas reactor and is arranged over the submersion depth into the fluid. The pressure in the inner area of the reactor is adjustable. An independent claim is included for a procedure for the production of biogas.
