JUSTIFICATION OF THE DESIGN OF THE SCREW EXTRUDER FOR THE PRODUCTION OF FEED

Abstract

In the feed industry, the extrusion of feed is a promising way to further improve the technology, which allows to improve the quality and nutritional advantages of compound feeds. Extruded feed is a clean feed of a new generation [1]. The article provides an analysis of existing studies of the design features of the extruder screw in the production of feed. Based on the analysis, the design of the extruder is justified, where due to the use of the crushing properties of removable scourges installed on the edge of the screw, its productivity increases during extrusion. The purpose of the study is to increase the productivity of the extruder, better grinding of raw materials, increase maintainability due to the use of crushing properties of removable scourges during extrusion during the processing of grain material.
