PROBLEM TO BE SOLVED: To provide a circulation type grain dryer which prevents dew condensation with a simple structure without having a heat insulating material adhered thereon. SOLUTION: The circulation type grain dryer is configured so that a receiving part 14 for receiving condensed water generated in side walls 3a, 3b and 3d and falling downward therefrom is provided in the side walls facing an air supplying duct 6. Thus, even if dew condensation occurs in the side walls 3a, 3b and 3d facing an air supplying duct 6 and condensate falls down on the side walls 3a, 3b and 3d, the condensate is received by the receiving part 14, and thus does not fall down onto a reflux part (crop collecting plate 11). Further, the receiving part 14 is formed as a gutter 14, and an end part 14a of the gutter 14 on the side of an air discharging fan 10 is formed in an open state. Thus, it is also possible to drop the condensate in the gutter 14 from the end part 14a to discharge from the air discharging fan 10 outside the machine together with the discharged hot air.
