PROBLEM TO BE SOLVED: To provide a fluidized bed drying apparatus exposing particles of a drying object including a great deal of moisture such as brown coal to gases with different temperatures and flow velocity conditions in regard to a fluidized bed drying apparatus. SOLUTION: The fluidized bed drying apparatus is composed of a particle input part, a drying part, a hot air supplying part, a dust collection part, a filter part, a heat exchange part, and a pressing part. A plurality of upper part partitions disposed at certain intervals is vertically formed to be separated from a porous plate in an upper part space of the drying part, lower part partitions arranged on both sides of the upper part partitions vertically formed to pierce the porous plate are disposed on the bottom of a lower part space, a space between the upper part partition and the lower part partition is partitioned by a separating plate, channel spaces respectively supplied with gases of mutually different temperatures and flow velocities are formed, and the gases with different temperatures and flow velocities are supplied to the channel spaces.
