PNSD Series Tall Form Pressure Nozzle Spray Dryer
1, PNSD model spray dryer/ pressure spray dryer /nozzle spray dryer
2, Liquid or slurry drying processor
3, Easy operation and control
4, Stainless steel
Descriptions
PNSD 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.
Working Principle
The solution, emulsion, suspension liquid or slurry are sprayed into fine beads in the hot air, going down from the top of the drying chamber to the bottom, the water will be evaporated to and the product becomes small granular product. Induce hot air from the top of drying tower, at the same time, pump the material liquid to the top of the tower by high pressure pump, the feeding solution becomes fine beads or small droplets through the pressure nozzle(s). When the droplets meet the high temperature hot air, the water will be evaporated immediately, and the material liquid is dried into dry product in a very short time, the product is discharged from the bottom of the drying tower, or from the cyclone (depend on the configuration). When the hot air contacts with the droplets, the temperature declines significantly, and the humidity increases greatly, and then will be exhausted by exhaust fan. The fine powder in the air will be collected through different separating devices There’re different fine powder separation and recovery devices, such as cyclone (the common type and various combination type), bag filter, cyclone + bag filter, cyclone + wet scrubber, and bag filter + wet scrubber etc. We should different fine powder separation and recovery devices as per the characteristics of product and requirements of customer. Depend on the product features and requirements, we might install secondary drying and cooling system (such as ZLG vibration fluid bed or pneumatic transportation), formulation system or powder sieving system etc after the spray dryer, or dehumidifier. The particle size of the product from pressure spray dryer is normally within the range of 120mesh to 20 mesh. If bigger particles are required, we suggest FL Fluidized Granulator or re-combined agglomerator.
