工艺流程图及工作原理：
从加料器加入的物料进入管径小的干燥管内，颗粒得到加速，当其加速运动终了时，干燥管径突然扩大，颗粒依惯性进入管径大的干燥管，颗粒在运动过程中，由于受到阻力而不断减速，直到减速终止，干燥管突然缩小，这样颗粒又被加速。如此重复交替的加速和减速，强化了传热、传质速率，使物料咋瞬间得到有效的干燥，成品随气流进入旋风分离器作气固分离，粉尘由布袋除尘器回收。
针对成品物料降水要求较高的物料：（中成品水：0.5-0.01%）可串联旋风干燥器对未干成品作二次干燥处理。
在旋风干燥器内气流夹带物料从切线方向进入，沿着内壁形成螺旋线运动，物料在气流中均匀分布与旋转扰动，增大了气固间的传热面积，延长了干燥时间，强化了干燥过程。
Working Mechanism
The materials are fed into a drying-tube with small diameter, and accelerated by the hot hair at a high speed. suddenly, the materials rush into a thicker part of drying-tube by inertia. In movement, the speed of material particles is gradually decelerated until the speed is constant. Then the drying-tube diameter becomes much smaller again so that the particles are accelerated again. Through repeated alternation of acceleration and deceleration, a high efficiency of heat-transferring and mass-transferring is obtained so that the materials are dried instantly. At last, the dried product goes with the cyclone separator for gas-solid separation, and dust is collected effectively by the bag filter.
As to the materials of high drying requirement (Dried product containing water: 0.5~0.01％), pulsed air dryer is applied to drying for the second time .
Air-flow with materials goes into the cyclone dryer in the tangential direction, then moves in a spiral along the inner wall of the dryer. The materials are evenly distributed in the air-flow with swivel disturbance so that heat-transferring area is enlarged, drying time is lengthened and drying process is enhanced.
该工艺设备适用于矿业、化工、轻工等行业的颗粒状、粉状物料的干燥，成品为粉状。
This type of equipment is made for mining, chemical industry, light industries for drying both particles and power materials. Finished product is powder.
