PROBLEM TO BE SOLVED: To provide a fluidized drier capable of preventing burning of dust including particulate flying apart from a dried object in a drier, to a surface of a far infrared ray radiator and fire breaking by jetting high-pressure air to the far infrared ray radiator mounted in the drying chamber. SOLUTION: This fluidized drier 1 comprises a dried object carrier 2 having a constitution of a horizontal recessed groove over both ends, and having a bottom face composed of a porous gas blowoff face 5 for carrying dried objects a while venting, a supply device 9 mounted on a starting end side of the dried object carrier 2 for continuously charging the dried objects onto the dried object carrier, the far infrared ray radiator 10 mounted at an upper part of the dried object carrier 2 for radiating the far infrared ray to the dried objects, and an air blower 11. A high-pressure air jetting duct 23 for jetting high-pressure air to a surface of the infrared ray radiator 10 for blowing away dust is mounted near the far infrared ray radiator. The high-pressure air jetting duct 23 has a high-pressure air jetting opening 24 composed of a narrow slot along the longitudinal direction of the far infrared ray radiator 10.
