| Abstract | ||
| Grading of olive fruits is important for export and local marketing. Grading parameters were length, width, thickness, and weight of olive. The mechanical grading, reduce the period needed to sort the olive varieties compared to manual grading, and the olives price depend on its size. The cylindrical grading machine for olive fruits was manufactured, and tested at the Agricultural, Engineering Department, Faculty of Agriculture, EI-Mansoura University. On the other hand, the experiment was carried out at Kafr-Awd, Aga, Dakahlia Governorate. The machine was tested in grading of Agize, Manzanillo and Picual olive varieties. The grading process was based on fruit parameters such as mass and dimensions and machine parameters such as grading cylinder rotation speed, grading cylinder slope and grading cylinder length. The grading efficiencies of all the olive fruit varieties under study increased with increasing the length and decreasing the tilt angle of grading mechanism. Result indicated the maximum grading efficiencies were 94 %, 92 % and 91 % for, Manzanillo, Agiza, Picual olives varieties, respectively. These values were obtained at grading cylinder length of 600-mm, cylinder rotating speed of 8 r.p.m, and grading cylinder tilt angle of O.0175Rad. | ||
