ABSTRACT:
An apparatus for compressing and heating a material to be treated, i.e., fibrous materials of plants such as true grasses or the like, changing the quality of the material, and solidifying the same. The material to be treated is delivered by a rotatable screw into and through a quality-changing chamber. During the passage of the material through the quality-changing chamber, the material is heated by a heating device. During the passage of the material through the quality-changing chamber, the material has its tissues destroyed, is softened, is compacted, and is solidified due to the compression by the screw and the heating by the heating device. A sensor senses a load applied to a motor and/or the temperature of the material being treated within the quality-changing chamber. A control system responds to a signal or signals from the sensor to control the load and/or the temperature.
