In order to dry materials (4) such as wood chips, the materials are laid in layers on air-permeable conveyor belts (11, 12) and moved forward. Heated drying air (17) is led through the conveyor belt (11 or 12) and the materials to be dried carried thereon within a drying zone (16), then within a filtering zone (15). Dust or toxic substance particles entrained from the drying zone precipitate again in the filtering zone and are deposited on the wet materials to be dried, so that the outgoing drying air (21) is clean. |
