Abstract (en)
The invention relates to a device for sorting tuberous crops, such as potatoes, according to size, said device being provided with a frame (1) and with a plurality of rollers (5) journalled in said frame (1), which are rotatable about at least substantially parallel axes of rotation. The rollers (5) are provided with projecting ribs (9) on their circumference. Furthermore means (2) are provided for supplying the crops to be sorted to the rollers (5) near one end of said rollers. Near the supply end the pitch between the successive ribs (9) is smaller than near the other end of the rollers (5). The ribs (9) have an at least substantially rectangular section. The construction is thereby such that an opening defined by opposite windings of a pair of rollers (5) lying side by side is at least substantially square. <IMAGE>
