Paddle dryer NARA Machinery Europe
NPD

The Paddle Dryer, developed and supplied by NARA, is an indirect dryer. It offers a wide range of possibilities for material treatment. The NPD is applied to dry, heat or cool organic or inorganic pellets, granules and powders. Filter cakes, thick pastes and even thick slurries having a sticky phase to pass during processing are handled in the machine. The raw material temperature changes when it gets into direct contact with the revolving, wedge-shaped rotating paddles and the jacket. All powder contacted surfaces are heated or cooled. Actually there are plants running with heating areas from 1,5 up to 280 m² and effective volumes between 0,0089 and 34 m³.
The NARA Paddle Dryer is well known for its compact construction and the consequently small need of installation space. This results from the high heat transfer coefficient and heat efficiency. These features combined with the self-cleaning effect of the paddles assure a homogeneous product, cooling or heating process for continuous and/or batch unit operations.
