Description
The spray dryer with closed circulation drying system works under enclosed environment. The drying requires inert gas which is generally nitrogen.

The closed circulation drying system is mainly used for drying of material containing alcohol or flammable and combustible solvent or material which can be easily oxidized so that it should not contact the air. By filling with nitrogen and some other inert gases, this dryer can protect the material from air.

The product produced by this dryer can be used to produce spherical material so that this dryer is suitable for production of high precision ceramic, tungsten carbide, silicon nitride, nano-ceramics, cemented carbide and some other powders, medicinal intermediate etc.

The following are some kinds of existing spray dryer with closed circulation drying system. You can directly choose from them or make some improvement on the base of specific types:
