Electronic weight sorting machine for post-harvest fruit: rotary sorter (5+1 grades, compact, budget-friendly) or linear sorter (9–12 grades, multi-lane, for high-volume packers). For apples, oranges, avocados, citrus, and more. Get quote.
Efficient post-harvest sorting is critical for fruit packers to meet market grade requirements and maximize profit. Electronic weight sorting machines have become the standard for delicate fruits like apples, oranges, avocados, lemons, and citrus – offering high accuracy (±2g) and gentle handling.
Fstsort offers two main types of electronic weight sorters to fit different scales of operation.
Which Electronic Weight Sorter Do You Need？
Feature | Rotary Weight Sorter | Linear Weight Sorter |
