This 15-roller sorting tool, equipped with flexible plastic covers, with adjustable spacing on two axes, allows precise ejection of the plant and any other waste larger than the grape berry (stalks, stems, leaves, snails, pieces of stump, etc.). The contours and the flexible material of our sorting rollers have been specially designed by our engineering department for optimal plant grip without triturating the fruit. The instantaneously adjustable spacing of the rollers combined with the possibility of lateral adjustment of the spacing of the contours allows precise calibration adapted to all types of grape variety.
