PROBLEM TO BE SOLVED: To provide a dryer in which a matter to be dried is prevented from riding over a stator even under a highly viscous semihardened state, and drawn in between disc blades through rotation thereof and moved while being stirred, the heating surface can be utilized effectively, the matter to be dried is prevented from hardening/adhering to the inner circumferential wall face of a drum or the disc blade or from rotating together, and high drying efficiency is ensured without causing extreme increase of power. SOLUTION: A hollow rotary shaft is passed rotatably through the shaft center part of a lateral tubular drum provided with a jacket on the outer circumferential surface. The hollow rotary shaft is provided continuously with a large number of hollow disc type stirring blades and the matter to be dried is stirred by means of the stirring blades while being heated with heating medium supplied to the jacket of the drum and heating medium fed through each stirring blade via the hollow rotary shaft. In such a dryer, a stator is suspended between the stirring blades from the upper inner circumferential wall face of the drum and a screw conveyor is provided on the outside of the outside diameter of the stirring blades in front of the stator along the longitudinal direction of the drum.
