In this paper,heat pump drying curves and drying rate curves of walnuts are presen-ted by using heat pump drying equipment to dry the Dali peeled fresh walnuts in different drying conditions .The results show that the drying temperature and the relative humidity of drying medium are important factors affecting the heat pump drying of walnuts.According to the drying curves and drying rate curves we obtained the following conclusions and then conducted the cor-responding experimental study:at the color fixing stage the drying temperature is set at 40 ℃, humidity 35%,and keeping for 8 to 10 hours long;at the late drying stage the temperature is set at 45 ℃,humidity 45%,maintaining 30 hours long.Under the above conditions the walnut drying is not only fast but with good quality.
