PROBLEM TO BE SOLVED: To obtain a grain drying machine in which the size is reduced, radiation area of far infrared ray is increased, energy saving effect is enhanced and combustion noise is reduced. SOLUTION: An upper stage storing section, a middle stage drying section and a lower stage grain collecting section are provided in the body of a longitudinally elongated drying machine. Two grain channels partitioned by a ventilation member is provided in the drying section, a hot air passage is provided between two grain channels, a return chamber extending in the longitudinal direction while being partitioned by a partitioning member is provided in the storage section above the hot air passage, a burner is provided on the front side of the drying machine body except the drying section, an exhauster is provided on the rear side of the drying machine body, an far infrared ray radiator having one end side communicating with the burner and the other end side extending to the vicinity of the exhauster is provided in the hot air passage, and a return pipe having one end side communicating with the far infrared ray radiator in the vicinity of the exhauster and the other end side opening into the hot air passage in the vicinity of the burner is provided for the return chamber in the drying section.
