The Nauta Dryer works on the principle of a conical mixer whereby the primary mixing screw is inclined at the same angle as the cone wall and conveys the product from bottom of the vessel to the surface.

The Nauta Dryer is a universal batch dryer suitable for drying materials such as powders, granules, pastes and viscous slurries, especially when products are heat sensitive, contain solvents and are toxic or explosive.
