Closed cycle drying concept with Nitrogen purged process gas circuit
Closed Cycle drying system
This drying systems features drying in an inert gas atmosphere where nitrogen recycles within the dryer. This closed cycle drying system can be used for the spray drying of feedstock containing organic solvents or in situations where the product can not get in contact oxygen during drying. Closed cycle plants are gas and powder tight, and are designed to the strictest safety standards. The inflammable solvent vapors are fully recovered in liquid form.

Semi closed cycle drying system
This drying system features either a partial recycle mode (recycle of up to 60% of the exhaust air as inlet air to the dryer, for effective waste heat utilization) or a self-inertizing mode, where direct air heating and a minimal air bleed create the low oxygen atmosphere necessary for drying aqueous feedstock that form explosive powder-air mixtures. If odor is generated during drying, the small volumes of air vented from the system can be effectively and economically incinerated. |
