1、原理：
洁净空气加热后进入干燥塔，在塔内热风中用二流体（或三流体)喷嘴将各种料液物化成微小液滴，与热风进行快速热交换，蒸发掉液料中的水分（或溶剂），并随热风排出，得到粉状产品。
Principle
The lean air is heated and entered into the drying tower,the raw material inside the tower is atomization and becomes mini liquid drops through nozzles of two or three liquids.The raw materials carry out heat exchange with the hot air rapidly to evaporate the moisture(solvent)in the raw materials.The moisture or solvent is discarged accompany with hot air,then the powder product is got.
2、特点：
①、尤其对粘性打、膏状、浆糊状物料。效果佳，其它设备无法替代。
②、实验型多品种，低温干燥应用广。
③、喷嘴结构简单，维修方便，运行费用低。
Features
①、It is better for raw materials that are large in viscosity and grease and paste.The other equipment can not replace it.
②、More Varieties and wide application in drying with lower temperature.
③、The nozzle is simple in structure, convenient in maintenance and lower cost in operation.
