A motorised conveyor (1) for moving a flow of harvest coming from a fruit harvesting machine is disclosed. The conveyor comprises a plurality of rollers (3) spaced longitudinally, the rollers being driven in rotation to move the flow of harvest on the rollers in a longitudinal direction (L1) between upstream (4) and downstream (5) transverse axes. Each roller (3) has a surface of revolution comprising grooves that extend transversely and continuously over its entire length, so as to enable transverse routing of the flow of harvest while it is being conveyed. The invention also concerns a sorting device comprising such a conveyor, a cleaning system comprising such a sorting device, and a fruit harvesting machine comprising such a sorting device or such a cleaning system.
