Determination of main parameters of vacuum camera the upgraded extruder
Developed and patented extruder with vacuum chamber. The aim of the work is theoretical research of working process of the vacuum chamber of the upgraded extruder. During the implementation of the objectives of the study were considered models of functioning of the vacuum chamber at “idle" speed (in the absence in the chamber of the extrudate) and during thermal vacuum treatment of the product during its dehydration. Analytical methods determined the time dependence of the output of the vacuum system of the extruder for a given mode of operation from the volume of the chamber, the working pressure in the vacuum system and the cross-sectional area of the vacuum hoses. The dependence of the pressure in the vacuum chamber of the extruder the moisture content in the processed raw materials and finished product, the horse of the cross section of the vacuum hoses, volume and pressure in the vacuum system of the extruder. The results of these theoretical studies to predict basic performance parameters of the vacuum system of the upgraded extruder and to compare them with the experimental results.
