1. The equipment is characterized by its compact frame, small size and large capacity.

2.Low energy consumption per unit of product, powerful drying capactiy.

3. Short drying time (3-30 seconds), also applicable for heat-sensitive materials.

工作原理:

从加料器加入的物料进入管径小的干燥管内，颗料得到加速，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，使物料在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 diameter, and accelerated by the hot hair at a high speed. Suddently, 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 air-flow into the cyclone sparator 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.

氮气先充盈入密闭式干燥设备系统中，被加热后（非空气）对物料进行烘干作业（原理同敞开型干燥设备系统干燥过程相类似）。烘干后的物料随气流进入旋风除尘器内进行气固分离；尾气进入离线式布袋除尘器内进行过滤除尘；再由引风机鼓入洗涤塔内进行洗涤。洗涤塔内的尾气进入冷凝除湿器内进行冷却、除湿；再被散热器加热重新进行烘干作业。
