FNSD Series Pneumatic Nozzle Spray Dryer
1, FNSD model spray dryer/ pressure spray dryer /nozzle spray dryer
2, Liquid or slurry drying processor
3, Easy operation and control
4, Stainless steel
Descriptions
FNSD pressure spray dryer is suitable for solution, suspension, slurry, paste material, etc. Liquid material is atomized to small fog drops. And fog drops contact with hot air directly in the drying tower. Moisture content is evaporated instantly. So spray dryer features high efficiency, high mass transfer area, and short drying time, in general it is 5~30 seconds. Operating temperature can be adjusted according to actual situation, in general inlet air temperature is 150~500°C. And its automation control degree is control, environment solution environment can be solved.
The clean air is heated and entered into the drying tower, the raw material inside the tower is atomization and becomes mini liquid drops through nozzless 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 discharged accompany with hot air, then got the powder product.
Features
1. It is better for raw materials that arelarge in viscosity and grease and paste. The other equipment can not replace it.
2. More varieties and wipe application in drying with lower temperature.
3. The nozzle is simple in structure, convenient in maintenance and lower cost in operation.
