Abstract
In present-day economic conditions, extrusion is one of the advanced feedstuffs and food production processes involving intensive manifold heat and force action. During extrusion, the main function is performed by a compression mechanism which includes a forcing screw unit built into the cylinder (cowling). The forcing mechanism performs the task of transferring material while concurrently compressing it up to a required pressure and increasing the material’s temperature due to compression and friction against the cowling's sides. The temperature affects the quality of the resulting product. Thus, the research aims at obtaining a heat balance equation to optimize the extrusion process and the operating parameters of the extruder itself.
