Abstract

This paper describes an experimental screw press for juice and cake separation. The constructive and structural schemes of the press are given, the characteristics of the main units of the equipment and the principle of its operation are presented. The algorithm of engineering calculation of juicer design is resulted, which is based on the calculation of pressing duration at different rates of screw rotation (? = 14653 rad/s, ? = 12,56 rad/s, ? = 16,75 rad/s, ?= 18,84 rad/s) and studied influence of compression pressure by changing of diaphragm holes (d=6•10-3 m; d=10-3 m; d=10•10-3 m; d=12•10-3 m). The proposed method of engineering calculation of the pressing process makes it possible to determine the optimum parameters in advance and to develop a press of any capacity depending on production conditions.
