STUDY OF A MULTI-SECTION SCREW FOR PROCESSING BIOLOGICAL WASTES
The article considers the technology and equipment for extrusion processing of biological waste on the basis of a multiple-screw auger. The efficiency of using extrusion as a technology for pro- cessing biological waste is substantiated. The technological scheme of the line for extrusion processing of waste is presented. A functional scheme of extrusion equipment for processing biological raw materials is proposed. A physical model of the extrusion process of multicomponent biological mixtures with the use of a barrier section has been developed for determining the rational geometric parameters of the mixing section and technological processing parameters. The physical geometric parameters of the barrier winding and the ranges of rational values of the rotational speed рациональные геометрические параметры барьерного витка и диапазоны рациональных значений частоты вращения шнека экструдера. of the extruder screw were determined by the method of physical modeling.
