CLASSIFICATION OF ENERGY-EFFICIENT SYSTEMS FOR THERMOPLASTIC EXTRUSION OF PLANT RAW MATERIALS

Abstract

The relevance of developing energy-efficient equipment for the extrusion of plant raw materials is due to the extremely energy-intensive nature of the classical technology, in which the conversion of electrical energy into thermal energy is carried out under conditions that are not advantageous from a thermodynamic perspective. This paper proposes a classification of energy-efficient systems for thermoplastic extrusion of plant raw materials. A detailed analysis of this classification will help to identify the most promising direction for the modernization of energy-efficient equipment that allows for the implementation of the process of cooking thermovacuum extrusion of raw materials with a high moisture content, moderate temperatures, and relatively mild mechanical stress conditions. Such operating parameters of the extrusion process are highly advantageous in terms of preserving the thermolabile ingredients of the processed raw material.
