This text and reference discusses the drying of grains, in particular the staple cereals, maize, rice, and wheat, and the oilseeds, soybeans and canola. The basic physical and thermodynamic properties of grain and air are examined, and the theory of the drying process is developed. Design of the optimum operating conditions for on-farm and off-farm dryers are presented. The book is written as an engineering text, but should also prove beneficial to all who are interested in the proper drying and storage of grains. Examples and problems are given in both S. I. and Imperial units.
