Analysis of Heat Pump Drying Characteristics and Kinetic Model of Chestnut Slices in Dabie Mountain

In order to study the heat pump drying process and characteristics of chestnut slices in Dabie Mountain,the drying kinetic model was established, and the drying process was optimized to improve the qualities after drying. This study took Dabie Mountain chestnuts as the research object to investigate the drying kinetics of heat pump. The mathematical model suitable for describing the heat pump drying characteristics of chestnut slices was screened through the linearization of seven commonly used drying models, and the most suitable mathematical model was determined and established by regression fitting of the model with the experimental data. The results showed that the predicted value curves of Page model were highly consistent with the measured value curves, and the Page model could be used to describe the moisture changes in heat pump drying process of chestnut slices.The results can provide certain references for the heat pump drying process in actual production of chestnut slices.
