Suspension conveyors are set up in a separate room in a meandering arrangement along parallel tracks transversely to the horizontally aligned extraction openings and inlet openings for air, and the inlet openings and extraction openings are connected through an air-conditioning plant, arranged outside the room, for dehumidifying and cooling the air extracted from the room.
