Abstract
Abstract 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.

Total Claims: 6
Claim 1
Independent Claim
143 words
In a grain bin having sidewalls forming a chamber for receiving grain, a plenum chamber for receiving air from an air circulating means and a perforated floor dividing the plenum chamber from the grain receiving chamber for allowing air to flow from the plenum chamber to the grain receiving chamber, the improvement comprising: an opening in a sidewall of said bin, part of said opening lying above said perforated floor and part of said opening lying below said perforated floor; a perforated plate disposed between said opening and said grain receiving chamber for preventing grain from flowing out of said opening but allowing the flow of air from said opening directly into said grain receiving chamber; and means for connecting said air circulating means to said opening for causing air to enter said plenum chamber and said grain receiving chamber through said opening.
