THEORETICAL STUDIES OF EXTRUDER PARAMETERS

Abstract

This article presents the results of theoretical research of scientific work, on the basis of which the regularities linking the productivity of the extruder, the moisture content of plant material, energy intensity, physical and mechanical properties, kinematic and design parameters are established. The drawing of the extrudate of wheat grains, which were obtained as a result of experimental studies, is given. A new design solution is proposed - the manufacture of a grooved edge of the extruder screw adjacent to the housing. A graph of the dependence of the extruder performance on the coefficient of internal friction of wheat grain is given. To determine the effective operation of the extruder, an estimated indicator is proposed.The purpose of the research is to increase the efficiency of the extruder in the processing of plant material by reducing the leakage of material between the inner surface of the extruder body and the edge of the screw screw.
