Nauta Dryers / Conical Dryers - Used and Surplus Inventory | IPP

For precision drying of heat-sensitive powders, slurries, and pastes, Nauta dryers offer efficient, low-shear mixing and moisture removal in a compact, conical design. With over 47 years of process equipment expertise, IPP gives you immediate access to used Nauta dryers sourced from 20 complete plant sites and included in our inventory of over 15,000 ready-to-ship pieces of equipment. Choosing a second-hand Nauta dryer from IPP allows manufacturers to reduce lead times, lower costs, and maintain high product integrity.

Nauta dryers, also known as conical screw dryers, use a rotating screw arm and orbital arm to gently lift and fold product while applying indirect heat and vacuum. This unique motion enables thorough, homogeneous drying with minimal mechanical impact, making them ideal for fragile or complex materials.
