The drying process of agricultural products is divided in two sections: the section of permanent rate of drying and the section of falling rate of drying. Considering the section of falling rate of drying, the equilibrium moisture is decreased. Using the Henderson's relation for the equilibrium moisture of wet air the authors proposed a completed i-x-w diagram of wet air and given material with a graphic representation of equilibrium moisture of the given material within the whole presented area of unsaturated wet air for wheat, rye, barley and oats. Such approach enables to perform a more precise evaluation of the drying process and modelling of the process using the thermodynamic relations of wet air.
