PURPOSE:To promote heat transfer, to carry out efficient dyring, and to prevent powder or granule from attaching to a hot plate, etc., by drying powder or granule by indirect heating with a hot plate, etc., and vibrating a fluidized layer itself and the hot plate, etc. CONSTITUTION:Powder or granule from the feed duct 2 is sent quantitatively by the rotary feeder 4, distributed uniformly to space between each of the hot plates 15, and made to flow in the fluidized bed 11. In the operation, the powder or granule is fluidized by vibration of the fluidized bed 11 by the vibra tion machine 14 and hot air from the hot air feed pipe 6, so it is successively transferred to the exist side. The powder or granule is dried by heating with the hot plates 15 and the hot air.
