PCT No. PCT/SE87/00378 Sec. 371 Date Mar. 1, 1989 Sec. 102(e) Date Mar. 1, 1989 PCT Filed Aug. 27, 1987 PCT Pub. No. WO88/01717 PCT Pub. Date Mar. 10, 1988.In a method and apparatus for drying a particulate material, for instance bark, the material is disposed as an annular bed (11) on a perforated disc (10). The bed is moved along the disc by being rotated about its axis by pushing members (12). A surface layer of moist material is continuously deposited on the upper surface of the bed in an area extending over the entire width of the bed, while at the same time a corresponding surface layer of dried material is continuously removed from the lower surface of the bed in a substantially corresponding area (17), so that the bed thickness is substantially maintained uniform over the entire area of the bed. A uniform moisture content is imparted to a drying medium which is passed through the support disc and the bed, the medium is preferably saturated with moisture before leaving the bed.
