Abstract

The main objective of the present study is to study factors affecting the mechanical grading of peach fruits. The studied parameters were:  grading-drum speeds of 4, 7, 10 and 13 rpm (0.05, 0.08, 0.12 and 0.15 m/s), fruit batch of 5, 10, 15 and 20 kg and types of grading cylinder (PVC and rubber coated cylinder) using constant grading tilt angle of 7o.
The main results in this study can be summarized in the following points: The maximum grading-efficiency of 98.9 % were obtained with grading speed of 4 - 7 rpm and feed rate of 5 kg.  Meanwhile, the minimum grading-efficiency of 83.6 % were obtained with grading speed of 13 rpm., and feed rate of 20 kg. The maximum fruit damage of 4.14 % was obtained with grading speed of 13 rpm (0.15 m/s) fruit batch of 5 kg and PVC cylinder. Meanwhile, the minimum fruit-damage of zero and 0.07 % was obtained with grading speed of 4 rpm (0.05 m/s), fruit batch of 20 kg and rubber-coated cylinder. The maximum machine productivity of 1075.6 kg/h was obtained with grading speed of 13 rpm (0.15 m/s) fruit batch of 20 kg. Meanwhile, the minimum machine productivity of 295.9 kg/h was obtained with grading speed of 4 rpm (0.05 m/s), fruit batch of 5 kg. The operation and production costs and rubber-coated cylinder) were 12.82 L.E./h and 26.98  L.E./ton at optimum conditions (grading speed of 7 rpm or 0.08 m/s, fruit batch of 10 kg and rubber-coated cylinder.
