Feasibility For An Improved Method Of Deep Bed In-Bin Grain Drying, Ali Ezell

Biological and Agricultural Engineering Undergraduate Honors Theses

In-bin grain drying reduces the moisture content of field harvested grain down to a level suitable for profitable storage. The traditional method for in-bin deep bed grain drying is conducted in a cylindrical grain bin with an approximate height to diameter aspect ratio of 1:2, a stirring mechanism, a bottom plenum, a fan, and a heating element. This method poses problems by having a drying front that can move through the grain bed too slowly causing over or under drying leading to losses. This method also requires a stirring mechanism with significant capital costs and the inability to use sensing …
