Substantiation of the rotary pin installation's working bodies parameters for processing of dried grapes

Abstract

The article offers the results of experimental research, the influence of the number of revolutions of the plate and the angle of inclination of the side wall of the plate, internal, and external diameters and heights of pins installed on the plate of a rotary pin installation, as well as the humidity of dried grapes on показателейits performance indicators. When determining the influence of the speed of the plate on the performance of the device, the speed of the plate changed from 200 min-1 to 350 min-1 with an interval of 50 min-1. As well as determining the influence of the angle of inclination of the side wall of the plate on the performance indicators, that when the angle of inclination of the side wall of the plate changes from 25 ° to 35 °, the degree of cleaning and loss of dried grapes increased, and the degree of damage decreased. An increase in this angle from 35 ° to 40 ° resulted in a decrease in the degree of peeling and loss of dried grapes, as well as an increase in the degree of damage to them. And at an angle of inclination of 35 ° or more, the probability of getting discarded dried grapes on the walls of the device increases, which negatively affects its quality indicators.
