چکیده انگلیسی
In order to separate haskaop berry and leaf during harvest, a vertical separation column was envisaged. The air drag coefficients of berry and leaf were measured to determine the proper air velocity in the separation column. The results show that the air drag coefficient of a berry set horizontally in the air flow was 0.959-2.21, and that of a berry set vertically was 0.322-0.977. The air drag coefficient of the leaves was 0.622-2.36. The minimum terminal velocity of berries (horizontally, 9.1 ms−1 and vertically, 11.0 ms−1) was significantly different from the maximum terminal velocity of the leaves (2.35 ms−1). Therefore, it should be possible to separate the berries and leaves using the air velocity from trial experiments in the separation column.
