Onion Roller Grading Machine
This FstSort onion grader comprises an elevator, a picking platform, and a grading unit. The elevator lifts and lowers automatically while its drum rotates. Damaged onions are manually removed on the picking platform; these rejects drop directly into side mounted chutes and are then carried away evenly by the conveyor below.

Onion Screen Grader
The FstSort Onion Screen Grader uses a multi-layer screen mesh gradient design to achieve precise sorting based on fruit diameter, with an average error of <1.84 mm and a grading accuracy rate of 97%. The screen mesh size can be quickly changed to accommodate different varieties (such as potatoes, beet or bulbs.).
