P-type ring dryer for thermally sensitive products
Optimize moisture control and prevent thermal degradation in your production process with this advanced ring dryer, designed for efficient handling of thermally sensitive materials.

Dries, Recycles, and Controls Moisture in Production
The P-Type Ring Dryer from GEA is engineered to handle thermally sensitive materials across various industries, including food, chemical, and pharmaceutical production. Utilizing a unique manifold system with centrifugal force, it efficiently recycles and dries materials such as modified starches and soy fibre while minimizing thermal degradation. The system’s adjustable splitter blade directs semi-dried material back into cooler sections for further processing, ensuring consistent, high-quality output. With options for open circuit or partial gas recycle, the dryer supports energy savings and system integration. Its flexibility allows use with different feed forms—including powders, pastes, and slurries—while maintaining close control over particle size and moisture content. Available configurations also include operation in inert atmospheres, making it adaptable for sensitive production environments. The P-Type Ring Dryer offers robust manufacturing capabilities and is suitable for high-speed, continuous operations with minimal maintenance demands.
