PROBLEM TO BE SOLVED: To provide a grain drying device capable of effectively preventing the interference of grain accumulated in a grain layer and a rotating disc. SOLUTION: This grain drying device 10 includes a grain tank 14 communicating with a drying section 15 for drying a grain, and receiving the grain, the rotating disc 90 for uniformly distributing the grain to every part of the grain tank by a centrifugal force while rotating at an upper part and a central part in a plane view in the grain tank 14, a lower screw conveyor 64, an elevator 70 and an upper screw conveyor 76 for supplying the grain to the rotating disc 90 in the grain tank 14, a full level sensor 96 outputting a signal according to an accumulation height of a part positioned at a lower side in the direction of a gravitational force to a rotating shaft 88 of the rotating disc 90 of the grain K accumulated in the grain tank 14, and a control panel 100 for stopping the lower screw conveyor 64, the elevator 70 and the upper screw conveyor 76 when the full level signal corresponding the full of the grain K in the grain tank 14 is inputted from the full level sensor 96.
