The objective of this research was to study the performance of heat pump dryer using refrigerant R32 and ginger was selected as testing material. The experiments were conducted under conditions; drying temperature of 45, 50, and 55 °C and air velocity of 1.0, 1.5 and 2.0 ms-1. Drying rate, the specific moisture extraction rate, the specific energy consumption, and the coefficient of performance of heat pump were tested. The results revealed that the increment of drying temperature or air velocity resulted in increment of drying rate, power of heat pump dryer, and specific moisture extraction rate whilst specific energy consumption decreased. Additionally, it was revealed that drying temperature or air velocity did not affect the coefficient of performance of the heat pump.
