Paddle Dryer

The Paddle Dryer is a drying system designed for efficient thermal processing of materials with good thermal stability, such as pastes, powders, and granules. It is also suitable for heat-sensitive materials and applications requiring solvent recovery or vacuum drying. By injecting a heating or cooling medium, the unit supports a range of operations—including drying, cooling, and crystallization. Its robust construction includes a drying chamber, dual rotating shafts with hollow paddle discs, and integrated discharge and moisture removal systems, making it ideal for closed-loop thermal processing.

How it works

Step Icon

Indirect heating jackets are installed in both the drying chamber and hollow paddle discs, using media such as steam, hot water, thermic fluid.

Step Icon

Wet material is fed into the chamber, where dual rotating shafts with paddle discs agitate and move it forward for uniform heat distribution.

Step Icon

The paddles ensure constant mixing, which improves heat transfer efficiency and prevents material buildup or localized overheating.

Step Icon

Moisture evaporates during the process and is extracted via an exhaust system that passes it through a cyclone separator, condenser, and scrubber.

Step Icon

The system supports continuous operation, offering reliable drying performance across various applications and feed types.
