A heating part heats a treating object present in the furnace body. An agitation part 41 is disposed in an agitation area on the inside face 33 of the furnace body and away from the discharge port with respect to the axial direction to agitate a treating object using a plurality of agitation blades 411 in response to the rotation of the furnace body. A discharge transfer part 42 is disposed in a discharge transfer area between the agitation area and the discharge port with respect to the axial direction on the inside face to transfer a treating object to the discharge port in response to the rotation of the furnace body using a screw blade 421 having a tilt angle at a part contacting the inside face relative to the axial direction greater than that of the agitation blades.
