Grapefruit Grading Machine

Product Overview – Choose the Right Grader for Your Operation

Grapefruit and pomelo are large, thick-skinned citrus fruits. However, they still require careful handling to avoid surface damage. Fstsort offers two grading solutions to match different budgets and accuracy requirements.

💡 Because grapefruit and pomelo are large fruits, the drum grader typically separates into 3 size grades (small, medium, large), while the electronic sorter can provide 6–12 fine weight grades for export markets.
