Based on this system, a serial of ex- periments was performed under four kinds of air cycle conditions. According to the experimental analysis, an appropriate drying medium-air cycle for the heat pump assisted fluidized bed drying equipment was decided, which is different from the commonly used heat pump assisted drying system. The experimental results concerning the drying operation performance of the new system show that the averaged coefficient of performance (COP) can reach more than 2.5. The economical evaluation was performed and the power consumption for removing a kilogram water from grains was about 0.485 kW.h/kg (H2O), which shows its reasonable commercial efficiency and great application potentiality in future market. 关键词：热泵流化床空气循环粮食干燥系统参数测量
