The subject of the invention is a method for the manufacture of briquettes from comminuted straw, as well as a device to manufacture briquettes from comminuted straw. The method consists in that comminuted straw is compressed in a continuous process using a screw-type extruder until the material reaches a temperature at which the material after pressing solidifies to a density exceeding 1.3 g/cm 3. The device has a screw (3) composed of three segments of decreasing helix pitches toward the outlet. The forming die (8) is housed in a tank (11) connected through a water system (12) to a cooler (13). The cooling system has a temperature sensor (17) installed, said sensor being part of the pump supply circuit (15). |
