<P>PROBLEM TO BE SOLVED: To provide a circulation type grain drying machine capable of executing uniform drying of high quality while suppressing damage of harvested buckwheat without requiring a special cost in response to a moisture value and its fragility fluctuating over a wide range in drying the harvested buckwheat. Ž<P>SOLUTION: This circulation type grain drying machine includes a hot air supplying means 4, a storage section 10, a drying section 11, a delivering means 16, a circulating means 2 and the like. This circulation type grain drying machine is provided with an intermittent drying operation in which a hot air drying process performing hot air drying by driving the hot air supplying means 4 and the delivering means 16, and a drying resting process for retaining the grain by stopping the hot air supplying means 4 and the delivering means 16 are alternately repeated, and also provided with a ventilating circulating operation for ventilating and circulating the grain by the delivering means 16 in a state of stopping the hot air supplying means 4, only in a case when a moisture value is more than a reference moisture value separately determined in starting drying by the intermittent drying operation.
