(54)TRANSPORT APPARATUS WITH VACUUM BELT


(57) A transport apparatus comprises an endless vacuum conveyor belt (310) having a plurality of perforations (311). The conveyor belt transports the particles along a transport direction (T) while they are aspirated to the perforations, thereby defining a moving transport surface (316). The transport surface extends in an essentially vertical plane (x-z), and the transport direction (T) is inclined upwardly relative to the horizontal direction (x). An inclined recycling tray (200) recycles particles that have fallen from the conveyor belt back to a feeding zone (150) purely by the action of gravity. A separating wall (600) separates a processing zone from a clean zone of the apparatus. The conveyor belt interacts with an elongate vacuum box, which is open along one side, the open side being covered by an elongate slider. The slider has suction openings with a cross section that varies along the transport direction (T).
