摘　　要：【目的】针对微波干燥过程中电磁场分布不均的问题,探究箱式微波干燥机干燥腔顶部磁控管的最优排布方式,以提升干燥效率并保障物料品质。【方法】针对高粱等农产品物料,设计了箱式微波干燥机干燥腔顶面的磁控管数量和排布方式。在微波作用距离为500 mm、560 mm时,基于HFSS软件仿真分析了六种磁控管排布方式下的电磁场分布情况。【结果】当微波作用距离为500 mm、磁控管为“一竖两横”品字型排布时,物料层中部区域的最大场强为707.5 V/m,且电磁场分布均匀,既能保证较高的干燥效率,也有利于提升物料的干燥品质。【结论】确定“一竖两横”品字型排布与500 mm微波作用距离是本设计较理想的磁控管排布方式和微波作用距离,为其他箱式微波干燥设备的设计与参数优化提供了参考。[Objective]Aiming at the problem of uneven distribution of electromagnetic field in the microwave drying process,the optimal arrangement of magnetrons at the top of drying chamber of box-type microwave dryer was explored to improve the drying efficiency and ensure the quality of the material.[Method]Regarding agricultural materials such as sorghum,the number and arrangement of magnetrons on the top surface of drying chamber of box-type microwave dryer were designed.When the microwave action distance is 500 mm and 560 mm,based on HFSS software,the electromagnetic field distribution was simulated and analyzed under six different magnetron arrangements.[Result]When the microwave action distance is 500 mm and the magnetron is arranged in a “one vertical and two horizontal pin zi shape”,the maximum field strength reaches 707.5 V/m in the middle area of the material layer,and the electromagnetic field distribution is uniform.It can not only ensure high drying efficiency,but also improve the drying quality of the material.[Conclusion]It is determined that the “one vertical and two horizontal pin zi shape” arrangement and 500 mm microwave action distance are the ideal arrangement of magnetrons and microwave action distance in this design,which provides reference for the design and parameter optimization of other box-type microwave drying equipment.
