NOVELTY - Processing the bedding of poultry farm, involves: performing drying of water-containing processed feedstock, and then heating in a pyrolysis chamber without air inlet with transfer of pyrolysis products into a solid product and steam gases with their subsequent partial condensation into liquid biofuel, where moist feedstock is granulated before drying, the obtained granules are dried at a temperature of 150 degrees C, and heating in the pyrolysis chamber produced at a temperature of 550 degrees C in the presence of gas heat-transfer agent.    USE - The method is useful for processing the bedding of poultry farm (claimed).    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a device for processing the bedding of poultry farm, which comprises vertically installed housing comprising the drying chamber and the pyrolysis chamber, unit of loading of feedstock, the unit of unloading of carbonic- mineral product, furnace chamber, at least, one unit for sampling of liquid biofuel, the chamber of mixing to define heat-transfer agent of drying, connected through the first gas circuit with furnace chamber, the first gas outline, made in the form of flue with gas blower, second gas circuit and the third gas circuit, made in the form of flue with gas blower, characterized by the fact that it additionally supplied with a granulator of feedstock, placed in the unit of loading of feedstock, where the first gas circuit made with the possibility of supply of the worked out drying agent and furnace gases in the chamber of mixing to define heat-transfer agent of pyrolysis for the security of external heating of the chamber of pyrolysis with obtaining of finished heat-transfer agent of pyrolysis, second gas circuit made in the form of flue by gas blower with the possibility of supply of worked out drying agent and finished heat-transfer agent of pyrolysis in the chamber of mixing to define heat-transfer agent of drying and providing of drying of granules with obtaining of dried granules and worked out drying agent, and the third gas circuit made with the possibility of supply of the worked out drying agent and furnace gases, formed due to the combustion detarred steam gases, obtained as a result of fractional condensation of steam gases of pyrolysis, to define heat-transfer agent of pyrolysis and providing inner heating of the chamber of pyrolysis.
