Grain drying apparatus of a type having a grain bin having a grain receiving chamber, a plenum chamber for receiving air from an air circulating mechanism, and a perforated floor separating the plenum chamber from the grain receiving chamber. An opening in the side wall of the grain bin is located partially above and partially below the perforated floor in order to eliminate the cold spot due to a lack of air flow normally found above grain drying fans. An annular flanged connection device is provided for facilitating easy connection and disconnection of the air circulating mechanism to and from the grain bin.
