THE INFLUENCE OF THE VOLUMETRIC FLOW OF RAW MATERIALS TO SUPPLY THE VACUUM PUMP UPGRADED EXTRUDER

Abstract

Theoretical and experimental studies of the mechanism of formation of the capillary-porous structure of extrudates have shown that one of the effective ways of forming the properties of extruded raw materials of plant origin is the thermal vacuum effect on it at the time of exit from the die of the machine. On the basis of the equation of the mass balance of the raw material processed by the extruder, the theoretical dependences are proposed, taking into account the influence of the thermal vacuum effect on the design performance (supply) of its vacuum pump. The obtained data allow to justify the main parameters of the vacuum line of the modernized extruder with sufficient accuracy for practical application by analytical methods.
