Solar desiccant systems for grain drying

The mathematical model for the Kathabar Spray-Cel System developed by the authors in a previous work was used to predict the temperature and humidity ratio of the air at the drying bin inlet. The unsteady grain cooling model developed by Huzayyin (Ph.D. dissertation, Kansas State Univ. at Manhattan (1972); Ref. [1]) is modified and coupled with the liquid desiccant system model to study the feasibility of using the system desiccated air in drying applications. The model shows the infeasibility of using desiccated air for grain drying. The liquid desiccant system was modified to simulate adiabatic operation and coupled to the drying model. The new system gave much better results, but its use for grain drying is still predicted to be economically unfeasible.
