Working principle of centrifugal spray dryer
The air passes through the filter and heater and enters the air
distributor on the top of the dryer. The hot air enters the dryer
evenly in a spiral shape. The material liquid is pumped from the
material liquid tank through the filter to the centrifugal atomizer
of the dryer, so that the material liquid is sprayed into very
small mist droplets. The material liquid contacts the hot air in
parallel, and the water evaporates quickly. It will be dried into
powdery finished product within time. The finished product is
discharged from the bottom of the drying tower and the cyclone
separator, and the exhaust gas is discharged by the fan.
Benefits
1. Stainless steel material, arc corner design and polyester powder
coated shell, prevents corrosion of acidity and alkaline air
effectively.
2. Imported Schneider electrical components which is more
stability.
3. PLC control system, make your research more easier and
efficient.
4. Build in oil-free air compressor, without any noise.
5. Self-priming peristaltic pump, avoid secondary pollution, make
sure whole process conducted steady and smoothly.
6. Narrow size distribution, more than 95% of the dry powders are
in the same range of particles.
7. Innovative tower wall purging device, improves the material
recycling rate.
8. High speed of drying, after spraying of the material liquid, the
surface area of material will be increased greatly, make your
research more efficient.
9. In the hot-air flow, 95%~98% of water can be evaporated at a
moment. You can finish material drying only in several seconds.
10. Especially suitable for drying the heat sensitive materials,
after drying, there's no need for smashing and sorting, so as to
reduce the operation procedures and save your time.
