Sažetak
This paper analyzes theoretically the motion and flow of eight fruit types, along rotating sizing machines. It starts from differential equation of fruit motion on a rotating disk of the sizing machine. A universal method that can generally be applied to determine the flow of all types of rotary sizing machine is developed. Flow analysis comprised sized fruit mass and flow. New empirical coefficients were introduced: extent ratio, feed ratio and distribution ratio. In particular, the influence of the relative speed of fruit on the capacity of sizing machines is researched. The results obtained for the adopted values extend, feed and distribution ratio ke = 0,7; kf = 1; kd = 0,5 coincide approximately with those reported to date for fruit flow rate on sizing machines. It was found that flow rates vary considerably, depending on fruit diameter and mass. Fruit numbers flow ranges from 8949 crops/h for apple to 40.157 crops/h for deep frozen raspberry. Mass flow varies from 229,1 kg/h for cherry to 2054,7 kg/h for apple.
