Operating Principle

This sealed circulation spray drying system operates in a completely enclosed environment using inert gas (typically nitrogen) as the drying medium. The system is specifically designed for materials containing organic solvents, toxic gases, or substances prone to oxidation.

Inert gas circulation protects sensitive materials during drying process
Closed-loop system with continuous dehumidification and reheating
Centrifugal atomization ensures uniform particle distribution
Automatic nitrogen inlet control maintains positive pressure system
Organic solvent recovery through condensation and separation

The system maintains positive pressure throughout operation, with automatic nitrogen supplementation controlled by pressure transmitters to ensure optimal drying conditions and safety.
