The drying of hay via a low-temperature liquid-desiccant drying system was simulated experimentally for three different climatic conditions. During the experiments, the desiccant regeneration temperature, the desiccant concentration, and the desiccant flow rate were held constant. Regeneration of the weak desiccant was accomplished under several simulated climatic conditions. System performance with a new cost-effective liquid-desiccant mixture (CELD) was determined. Results show that the drying of hay and other agricultural products with low-temperature liquid-desiccant systems can be cost effective and potentially preserve the quality of the product. In addition, simulation results of a conventional heated-air drying process were compared with the results of the low-temperature liquid-desiccant drying process.
