Spiral roller grader SRS

The Sormac spiral roller grader is used for grading peeled root products, particularly potatoes. The machine is equipped with a number of plastic rollers provided with a spiral-shaped groove. The depth and width of this groove increase towards the end of the roller. The groove is shaped in such a way that between each roller pair perfectly square openings of increasing size are formed.

Via an infeed hopper with V-channels, the product is transported to the machine.

It is important for the infeed to be distributed evenly across the width of the grader. The grooves in the rollers transport the product forward until the groove openings become so big that the potato falls through them. The required gradings are set by adjusting the separation plates underneath the machine
