The authors have been working for 50 years in the research and development of drying in agriculture. In the way of drying applied, warmed air is used as the drying medium. The thermodynamics of wet air is used for the analysis of these processes of drying in the calculations and in graphic demonstrations applying an i-x diagram of wet air. This diagram does not include any information about the state of the dried material. The authors therefore enlarged this i-x diagram with the equilibrium moisture contents of the dried material. In their work, the authors present a method using this enlarged diagram and, as an example, the i-x-w diagram of wet air and equilibrium moisture of wheat grain.

Keywords: drying in agriculture; equilibrium moisture; thermodynamics; sorption isotherm
