Paddle dryer
NPD
NARA Machinery Europe
Paddle Dryer is one of the indirect heating type dryers, that without using any gas as heating medium, dries (cools or heats) powder material (organic or inorganic) by direct contact with hollow cuneiform type rotating heaters (paddles).
All or nearly all of heat capacity necessary for drying are brought by the direct heat transfer from the paddle shafts and the jacket. The hot air is only used as a carrier preventing vapors from dew formation.
FEATURES
Compact construction and small installation space.
Big heat transfer coefficient and high heat efficiency.
Self-cleaning effect among paddles.
Easy control of temperature and residence period of processed material.
Material with high moisture content can be processed.
Piston flowability is secured.
