Working Principle:
Liquid material is atomized through a special pressure nozzle with a high-pressure pump. Hot air enters the dryer after being adjusted by an air distributor. The material and hot air is mixed in the dryer, rapidly carries on heat and mass transfer. Powder or granular products are produced in a very short time. Products with larger particles size are discharged form the bottom of the dryer, smaller particles enter the cyclone with hot air. The exhaust gas is discharged into the air after dust removal in a scrubber. The dryers can be divided into high, middle and low pressure spray dryers according to different pressures of atomization, while taking into account different flow fields, they are divided into co-current, fountain mode and counter-current spray dryers. 

Characteristics:
1. High operational flexibility on non-adhesive or low-adhesive liquid materials.
2. Simple structure of the spray nozzle, easily used and maintained.
3. Less power consumption, low cost.
4. The hollow spherical product with big particles, good mobility and solubility.
5. Can be used to spray-cooling granulation process, such as paraffin, grease particles, special resins, etc.
