针对塔式圆形干燥箱内风量分布不均匀的问题,设计了导风板装置,通过理论计算分析了导风板的工作原理并求出导风板的数学模型,然后进行数值计算,模拟在导风板的作用下热风在干燥箱内的分布状况,最后通过葡萄干燥试验观察葡萄的干燥速度,结果表明,增加导风板装置后,风量在干燥箱内分布均匀,物料干燥速度一致。 Aiming at the problem of uneven distribution of air volume in a tower round dry box, a wind deflector device is designed. The working principle of the wind deflector is analyzed and the mathematical model of the wind deflector is obtained through theoretical calculation. Then, The distribution of the hot air in the oven under the action of the wind deflector, and finally the drying speed of the grapes through the grape drying test. The results show that after the air deflector is increased, the air volume is evenly distributed in the drying oven and the drying speed of the materials is consistent.
