FIELD: energy.
SUBSTANCE: invention can be used in bio-energy as a universal aerobic reactor for processing into fertilizer animal manure, bird droppings, green mass, household and other agricultural and forest waste bio-stock. Biodrum comprises a cylindrical body on the roll sets electromotive drum and auger with blades on its inner surface, a feeder, and a discharge mantle heater. Axis of the housing tube with holes is installed at fixing thereon a porous hollow screw. One end of the pipe rotatably disposed on the support post housing and the other has circumferential holes and connected to a reversible screw electromotive. To a hole at the end of the pipe is pressed by moving the annular coupling tube connected to the gas blower. To boot device is connected pump extruder incoming raw materials. On the outer surface of the housing is installed pipework "heating-cooling", the entrance is through a tube connected to a liquid injection pump. One outlet pipe routing in the shell through the first discharge valve connected to the boot device, and through the second gate - the entrance of the heat accumulator, the output of which through the third valve connected to the inlet of the pump. Yield pipework and through the fourth valve is connected to the input of the reverse drive of cold water, the output of which is connected through a fifth valve with cold water and the backbone through sixth valve - with the pump inlet.
EFFECT: with this arrangement reduces the time the aerobic process and improves quality of the fermented product.
