The Trio 90-4 model is suitable for grading and inspecting potatoes, Brussels sprouts and onions. At the filling point, a movable base with intermediate slide is installed for the control of product feed.
The product is then graded into four sizes in the grading section. Undersize and oversize product is discharged to the side and the main grades of product go straight to the roller inspection conveyor.
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 then topples forward at an angle. This means that the product is never given the chance to find its way between the grading holes, which ensures great accuracy. Jump grading depth and direction can easily be set by means of two hand-wheels so that you can always choose the optimum adjustment to ensure the best jump movement for the various types of seed and ware potatoes, as well as for onions and Brussels sprouts. At the end of the roller inspection table two double bag brackets with a flap are mounted to load product into bags. The flap enables the operator to switch between two positions for continuous bag filling.
