| Abstract: | Heat pump drying system is a state-of-the-art drying technology for seed and other biomaterials for its high quality drying, low energy consumption, environmentally friendly performance, and wide range of applications. Based on the First and Second Laws of Thermodynamics, the heat pump drying system was analyzed. It can be concluded that the auxiliary condenser is a ideal option for the closed system. It can also be shown that there exist an optimum evaporation temperature at which a maximum dehumidification rate and exergy efficient of the whole system can be achieved for the heat pump cycle. |
