The clean air is heated and entered into the drying tower, the raw material inside the tower is atomizied and becomes mini liquid drops through second-rate or third rate nozzle. 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 discharged accompany with hot air, then the powder product is got.

It is better for raw materials that are large inviscosity and grease and paste. The other equipment can not replace it.

More varieties and wipe application in drying with lower temperature.

The nozzle is simple in structure, convenient in maintenance and lower cost in operation.
