PROBLEM TO BE SOLVED: To provide an indirect heating type drying device for uniformized high filling rate for objects in a casing with flexibility and surely, even in a case in which, for example, an object having a different property is to be dried.SOLUTION: In an indirect heating type drying device, a heating medium 25 is circulated in a rotating shaft 4 and agitation blades 20, and an object in a casing is indirectly heated for drying processing. At least a part of agitating blades 20 of the indirect heating type drying device includes a fan-like fixed blade part 21 provided by being fixed to the rotating shaft 4, and a movable blade part 22 which is overlapped on the fixed blade part 21 in axial line O1 direction, to be reciprocatable from a side end part of the fixed blade part 21 to the outside in circumferential direction. |
