Organic material and animal excrement is fermented in an accelerated manner in closed systems in order to produce energy, such as biogas and heat, wherein, as a rule, the material is moved around or constantly shifted, respectively, in known devices. According to the invention, the material to be fermented, organic waste and excrement, preferably from large-scale animal maintenance, is brought together and fed to inclined shafts from above, wherein it sinks down by means of its own force of gravity and is mixed at intervals by means of a mixing angle attached at a chain hoist. The inclined bottoms of the shafts form the heat exchanger units, for which purpose the outer defining walls can also be used. The entire system is completely insulated and can be coated automatically from above.

A method for the aerobic fermentation of solid organic materials, such as agricultural and foodstuff waste products, including excrement, and the simultaneous production of heat and high-grade, hygienically acceptable fertilizer, comprising feeding the material to be fermented into at least one shaft and conducting the material through the at least one shaft, the at least one shaft comprising heat exchanging means, the material conducted through the at least one shaft forming a layer adjacent the heat exchanging means and a layer away from the heat exchanging means, mixing the layer adjacent the heat exchanging means into the layer away from the heat exchanging means, the shafts being mounted in an enclosed, thermally insulated housing, the housing having a top portion and a bottom portion, withdrawing hot air produced by the fermentation process from the top portion of the housing, adding fresh air to the hot air and introducing the hot air into the bottom portion of the housing underneath the material to be fermented, and removing the fermented material from the housing.
