| Abstract | ||||
| The main objective of the present study is to develop, construct and evaluate the performance of a small-scale grading machine to suit grade fresh fruit like apricot (Canino variety). The performance of the grading machine was carried out to investigate some engineering parameters such as: four different grading speeds 5, 8, 11 and 14 rpm (0.05, 0.08, 0.12 and 0.15 m/s), fruit batch of 5, 10, 15 and 20 kg and two type of grading cylinder (PVC and rubber coated cylinder) using constant grading tilt angle of 7o on grading efficiency, fruit damage and grading productivity. Physical and mechanical properties of apricot fruits (Canino variety) under study, was studied to evaluate the performance of developed a small-scale grading machine. The optimum conditions of grading machine to be operated at the maximum efficiency are: Grading speed of. 8 rpm. (0.08 m/s), fruit batch of 10 kg and rubber coated cylinder. Achieved grading efficiency of 98.41 %, fruit damage of zero %, and productivity of 610.17 kg/h. Operation costs was 7.37 L.E./h and 12.1 L.E./Mg. | ||||
