Process features:

1. Enjoying high efficiency and energy saving, vibration can make the material always in fluidized conditions,thus increasing the effective heat transfer coefficient, which can save energy by 30-50% if comparing with fixed drying bed and air flow drying bed.

2. With little damage to the material surface, it can be used for drying of crushed materials,irregular particulate of material has no influence on working effect.

3. Having uniform fluidization and free of dead bed and penetration, it can get uniformly dried, cooled and humidified products.

4. Good adjustability and wide application, thickness of material layer, internal moving speed and amplitude can be stepless adjusted.

5. Excited and driven by vibrating motor, it features stable running, convenient maintenance, low noise and long service life.

6. Full close structure is adopted to prevent crossing contamination between material and air, realizing clean operation environment and improving the labor conditions.

7. For pulverizing of special material, 2nd phase collecting (pulse) device can be added, recovery rate reaching over 99.6%.

工艺流程及内部结构简图: 

Scheme of process flow and working principle:

振动流化床干燥设备是由振动电机产生激振力使床身振动，被干燥物料在这定向激振力的作用下跳跃前进，同时流化床底部输入的热风使物料处于流化状态，物料颗粒与热风充分接触，去掉水份从而达到理想的干燥效果。物料从加料口进入，振槽上的物料与振槽下部通入的热风正交接触传热、传湿，含尘空气由引机引出，干品从出料口排出。

Vibrating motor generates exciting force and makes the bed vibrated, material to be dried is jumped forward under the certain direction exciting force. at the same time, hot air input from bottom of fluidized bed makes the material in fluidized status, at which.material particulates make sufficient touch with hot air, thus removing the moisture content and realizing the purpose of drying. Fed material on the vibrating tank makes cross-out touch with hot air fed from bottom of vibrating tank, thus transferring the heat and moisture, meanwhile, dust air is output from draught fan, dry product is discharged from material outlet.

（密闭循环型离心式喷雾干燥设备工艺简介）

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（原理同敞开型离心式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。
