Flexible Grader

Boost the market value of your potatoes

The Flexible Grader is widely deployable and can be mounted behind various brands of receiving hoppers, providing a simple way for you to clean or sort the product. The roller units are versatile and flexible in use and can be placed directly behind the receiving hopper or used independently in the storage line. Switching between cleaning rollers and grading rollers can be done quickly, and the cleaning intensity and/or grading size is flexibly adjustable. The Flexible Grader can be expanded with the Flow-Pin, which prevents product damage caused by too much time spent on the rollers. The Smart-Pin is also available to ensure that you obtain consistent product cleaning quality without interruption of the storage process.

Separate cleaning and grading by product size

No-one knows your cleaning and grading needs better than you do. With our Flexible Grader, you can choose to clean and/or sort behind the receiving hopper. The gap width and the position of the rollers can be set precisely. The roller unit is available with RZ smooth rollers, SZ spiral rollers, SU sorting rollers or PU star rollers.

Easy to operate

The user interface of the separate roller units from Dewulf utilises pictograms, making them very easy to operate. The Flexible Grader is also equipped with Start-Control: With a single push of the start button, all connected machines will start in sequence with delay timers. This prevents current spikes in the power grid and optimises both the capacity and the product-friendly handling.
