Abstract

The principle of operation of a single-screw extruder is based on multiple conversion of one type of energy into another with a sufficiently low efficiency. It is obvious that at the final stage of the working process of the machine part of the energy in the form of heat of water vapor released from the extrudate at the time of decompression explosion is lost forever. The paper presents theoretical provisions to improve the energy efficiency of the working process of a single-screw thermal vacuum extruder by replacing part of the energy of the electric drive of the machine with the energy (heat) of hot steam released from the extrudate during its intensive dehydration under low pressure.
