<P>PROBLEM TO BE SOLVED: To solve a problem that a part of grain charged and supplied to an exhaust chamber is likely to be sucked and discharged from an exhaust port to the outside of a machine, though the work is hygienically performed by sucking and discharging dust by suction air from the exhaust port formed on a side part of the exhaust chamber in a configuration where the grain is charged and supplied from the exhaust chamber. Ž<P>SOLUTION: In this circulation type grain drying machine provided with the exhaust chamber 6 for exhausting and guiding the drying air to a suction air port 3 on one side along the outer side of a drying chamber 2 for circulating and drying the grain by the rotation of a feed valve 1 while guiding the feeding and flowing-down of the grain, and guiding the grain supplied from a supply port 4 formed on an outer side to a grain collecting gutter 5 at a lower part, an opening/closing plate 7 is provided to open and close the exhaust port 3 section of the exhaust chamber 6. When the grain is charged and supplied, the grain is supplied from the supply port 4 to the exhaust chamber 6 in a state that the opening/closing plate 7 of the exhaust port 3 is closed to fully close the exhaust port 3 or to partially close the exhaust port 3.
