ABSTRACT:
A bulk material processor includes a barrel assembly with first and second ends, the first end having an inlet and an outlet. A rotor assembly is rotatably mounted within the barrel assembly and includes a screw auger positioned within a generally cylindrical body. Vanes extend longitudinally along the rotor body and project outwardly therefrom. A feeder assembly delivers bulk material to the barrel assembly inlet for augering through the rotor assembly. Upon exiting the rotor assembly, the material is swept around the inside of the barrel assembly for intermittent exposure to infrared radiation from a heater assembly mounted on top of the barrel assembly.
