The Roll-Grading system performs product cleaning and grading functions, as it conveys it along the production line.
The first set of rollers moves the product, removing small size rejects that are conveyed to the first hopper. Thus, leaves, grass, pedicels, and other small sizes rejects are removed.
The second set of rollers is used for grading the product. Products bigger than a specified size move towards the exit, while smaller ones are collected in a second hopper. The size deemed as waste can be manually adjusted in the first set of rollers and the grade can be adjusted in the second set of rollers. The systems is available in two types: Roll-Grading 100 and 150.
