PROBLEM TO BE SOLVED: To shorten a waiting time by shortening a cooling operation time of a burner when a temperature of the burner is low because of an abnormality of the non-ignition of the burner in a circulation type grain drier. SOLUTION: This circulation type grain drier comprises a driving means of a drier body and a burner combustion means of the burner 13 operated by a drying switch, a controller 40 with a nonvolatile memory capable of controlling the driving means of the drier body and the burner combustion means of the burner 13, and a burner combustion detecting means 70 for detecting the combustion state of the burner 13. When a burner combustion detecting means 70 continuously detects the non-combustion state of the burner by the prescribed number of times, though the drying switch is turned on several times, and the combustion operation of the burner combustion means is performed several times, a combustion output from the controller 40 to the burner combustion means is stopped, and the drying means of the drier body is driven for a prescribed time shorter than a time in ordinary operation, and then stopped.
