The present invention relates to a fluidized bed drying apparatus capable of easily dehumidifying fluidizing gas flowing thereinto by raising relative humidity in the fluidizing gas through the heat exchange of the fluidizing gas. According to the present invention, a fluidized bed drying apparatus capable of dehumidifying fluidizing gas comprises: a casing having an inner space, having a particle supply part supplying particles to be dried, having a particle discharge part discharging dried particles, and a gas outlet discharging the fluidizing gas; a bed installed in the inner space of the casing, partitioning the inner space up and down, and having a plurality of dispersion holes; a fluidizing gas chamber positioned on the lower space of the bed, connected to a fluidizing gas supply pipe, and supplying the fluidizing gas upwards through the dispersion holes; a fluidizing gas inlet pipe into which the fluidizing gas supplied from the outside flows; a heat exchange part connected to the fluidizing gas inlet pipe, and exposed to a drying chamber as the upper space of the casing; a fluidizing gas outlet pipe connected to the heat exchange part; and a water remover connected to the fluidizing gas outlet pipe removing water in the fluidizing gas, and connected to the fluidizing gas supply pipe.
