Abstract: Sorting table with sorter rolls eliminates foreign matter remaining mixed in with the products of the harvest of small fruit. The sorting table features a sorting system constituted by a succession of rotating rolls of cylindrical shape arranged in parallel so as to form a mobile sorting plane, and a locomotion device, allowing the rotating drive of the rolls in the same direction, so as to allow transporting the grapes dumped on the upstream part of this sorting plane, in a direction that is perpendicular to the axis of the rotating cylindrical rolls and over the entire length of the sorting plane. The rotating cylindrical rolls allow the passage and drop-off of only the small fruit to be sorted, whereas the foreign matter of a size larger than that of the latter remains on the surface of the mobile sorting plane and is evacuated at the downstream end.
