( 5 )本文创造性地设计了新型的双格栅均风装置并设置在压力喷雾干燥塔的上部，强化了干燥塔内气、液两相间的混合，最大限度地消除了干燥塔内的无效区域，对热敏性物料的干燥更显出该结构型式的优越性。 - The dehydration time is square of the droplets diameter so the small diameters of the droplets can cut down the drying time then reduce the height of the drying chamber . to the combined spin - flow pressure spray drying , the diameters of droplets are small and the dehydration rate is higher so keeping the qualities of the dried products we can increase the speed of the inlet wind and reduce the temperature of the outlet wind thus can improve the evaporation intensity of the drying chamber and the average energy utilization of the drying equipment
因雾滴的脱水时间与其直径的平方成正比，减小液滴直径有利于缩短干燥脱水时间，可有效降低干燥塔的高度；由于旋流式组合压力喷嘴雾化滴径的减小，脱水速度明显加快，在不影响干燥物料性质的前提下，适当提高进风温度，同时有效地降低排气温度，有利于提高干燥塔的蒸发强度，也有利于提高干燥设备的平均能源利用率。
