Abstract
The purpose of the research is theoretical substantiation of the influence of the thermal vacuum effect for the volume consumption of raw materials in the extruder with vacuum chamber. Theoretical studies of the working process of single screw extruders allowed us to obtain analytical expressions, which can be used to determine the volume flow rate of extruded raw materials serial machine. For extruders using thermal vacuum effect in their work, this theory does not allow to obtain acceptable results, since it does not take into account the fact that the technical solution implemented in the experimental extruder, compared with the serial machine allows to increase the coefficient of explosion of the extrudate in 1,5...2 times. In turn, this significantly affects the volume performance of the extruder and does not allow to determine with the necessary accuracy the structural and technological parameters of the vacuum chamber and its sluice gate. In this regard, in the carried out researches, on the basis of the equation of balance of mass of the processed raw materials which is in a path of the extruder and its vacuum chamber, the coefficient consid-ering influence of thermal vacuum effect on volume consumption of raw materials in the experimental extruder is theoretically proved, and also communication of this coefficient with other significant parameters of process of extrusion is established. The obtained results can be useful for further theoretical studies of extruders with thermal vacuum principle of operation and allow to calculate by analytical methods the main parameters of the vacuum chamber of machines performing thermoplastic extrusion of vegetable raw mate-rials.
