Technical Parameters:
Dry powder recovery ≥ 95%
Residual solvent ≤ 2%
System oxygen content ≤ 500PPM
Electric riot control EXDIIBT4
Equipment system positive pressure state

In this case,
The equipment is operated in a confined environment, using an inert gas as the drying medium (typically nitrogen). Mainly in the drying process to prevent oxidation or slurry containing flammable and explosive solvents. By nitrogen or other inert gas, to avoid contact with the air. The device produces good consistency of products, good liquidity, suitable for ceramics, cemented carbide, pharmaceutical intermediates and so on.
The drying medium is usually nitrogen, automatic control, automatic matching of internal pressure to ensure that the system pressure balance; the entire drying process is completed under the protection of nitrogen, organic solvents can be recovered at the same time.
Centrifugal spray method, can get the average particle size of 10-100μm powder. Its observation under a microscope into a spherical, fluid, loose than the consistency of good, to meet the late automatic press continuous production.

Closed loop spray drying typical process:

 1 - Drying tower 2 - Cyclone 3 - Tank 4 - Induced draft fan 5 - Circulating spray tower 6 - Cooling system 7 - Blower 8 - Heater
