FIELD: agriculture.SUBSTANCE: invention relates to a method of manufacturing briquettes of straw of grain crops, which is shredded and then compacted, at that the shredded straw is preliminary dried to a moisture content of 15-20%, and then is fed to a screw extruder and is gradually compressed up until it is heated to a temperature above the 290°C and its density is no more than 1.3 g/cm, then the resulting mass is extruded in the form of a cylinder having a uniform structure, and during the extrusion a constant temperature not exceeding 340° is maintained in the forming die of the extruder. Also the device for manufacturing briquettes from shredded straw is disclosed.EFFECT: resulting briquettes have a uniform stable form, which does not change during long-term storage.3 cl, 2 dwg, 3 ex |
