摘　　要：为解决陈皮在热泵干燥过程中干燥不均匀、效率低等问题,运用计算流体力学(Computational Fluid Dynamics,CFD)对陈皮热泵干燥室的内部气流分布进行模拟仿真,并对导风板的排布方式进行优化模拟仿真分析。研究结果表明:有导风板时,干燥室的内部气流分布较均匀;当倾斜角度为30°、侧边间距为80mm、垂直间距为260mm时,能够有效提高陈皮热泵干燥室的气流分布均匀性和干燥效率。In order to solve the problems of uneven drying and low drying efficiency of Chen Pi in the heat pump drying process,the internal airflow distribution of Chen Pi heat pump drying chamber was simulated by using computational Fluid Dynamics(CFD)and analyzed by simulating the arrangement of air guide plate.The research results show that the internal airflow distribution of the drying chamber is more uniform when there are air guide plates;when the tilt angle is 30°,the side spacing is 80 mm and the vertical spacing is 260 mm,the uniformity of airflow distribution and drying efficiency of the drying chamber of Chen Pi heat pump are effectively improved.
