FIELD: agriculture. SUBSTANCE: invention relates to agriculture, in particular to equipment for processing organic wastes at treatment facilities. Mobile fermenter comprises gas blower. Latter is made with possibility of oxygen generator and ozone generator sequential connection to it. Cylindrical body installed on the machine and having a loading and unloading hatch is fixed on the pipe. One end of the pipe is connected to an electric drive connected to the power supply, and the other end has circumferential holes and to it there pressed is an annular coupling sliding along the pipe. Coupling is connected to gas blower. Carbon dioxide gas sensor is installed inside the cylindrical housing. On the tube there are sliding current collectors, and on the inner wall of the cylindrical housing there are perforated tubes-ribs fixed, which are filled with "brush bio-loading" containing aerobic bacteria. On inner side walls of cylindrical housing there are insulating plates with current-conducting metal sheets, insulated terminals of which are connected to one sliding current collector located on pipe and connected to power supply, and the other sliding current collector is connected to the carbon dioxide sensor placed inside the housing, and is configured to be connected to the operator's measuring device. At that, the pipe is perforated along the housing length and is arranged at an angle to the central axis of the cylindrical housing. EFFECT: invention ensures achievement of technical result consisting in improvement of reliability and productivity due to better mixing of raw materials in drum design in form of "slanting barrel" and reduction of "lag-phase" time by heating of each new raw material load upon maximum release of carbon dioxide with sequential action on raw material with air, technical oxygen or ozone.
