Abstract:
Over the past decade,high demand for dried agricultural products has led to a rapid expansion of high density heat pump drying technology worldwide.The drying rate of materials in the drying room is closely related to the distribution and management of air flow.In this paper,the operating principle and characteristics of heat pump drying system are described,and the domestic and foreign researches are summarized from three aspects,namely,interior structure,working condition design and energy-saving form. The paper points out that the dry indoor airflow uneven distribution is the main cause of the low drying efficiency poor quality,and analyzes the various air management approaches,including that different way of back to the wind can avoid dry indoor form circumfluence,and optimized geometric structure can reduce the resistance in the process of fluid flow. Thus,the comprehensive performance of heat pump drying chamber can be improved. In view of the lack of research on dehumidification method in drying chamber,further research is needed on how to reasonably design the location of dehumidification outlet and the corresponding design of different pipeline layout,so as to improve the reasonable distribution of heat and humidity in drying chamber.
