• supertrio9 4A complete, compact & mobile grading & inspection unit
  • Product-friendly; one short product route

The SuperTrio 90-4 model is suitable for grading & inspecting potatoes and onions. The product feed to the grading section is adjustable to guarantee an even flow. The product is then graded into four sizes in the grading section. Undersize and oversize are discharged to the side, and the main grades of product go straight to the inspection conveyor belt for inspection.

The unique ‘jump-action’ grading technique ensures an extremely accurate and product-friendly grading process. With every ‘shock’ movement the product is tossed up at an angle and topples forward at an angle as well. This means that the product cannot escape the grading holes by manoeuvring between them, ensuring great accuracy.

Both jump grading depth & direction are easily adjustable by two hand wheels in order to choose the best jump movement for potatoes & onions. The inspection table has a frequency control to adjust the speed while inspecting.
