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.

Primary uses across industries

In pharmaceutical manufacturing, Nauta dryers process APIs, excipients, and intermediates.
In chemical processing, they dry resins, pigments, and specialty powders.
In food and nutraceuticals, they handle protein powders, cocoa, and botanical extracts.
In cosmetics and personal care, Nauta dryers dry emulsions, clays, and natural additives.
In additive manufacturing, they dry specialty polymers and metal powders.

Types of materials processed

Fine powders and granules requiring uniform drying
Heat-sensitive, shear-sensitive, or hygroscopic materials
Slurries and pastes that can be dried under vacuum

Common materials of construction

Nauta dryers are built to meet high purity and durability standards:

Stainless steel for food, pharma, and chemical-grade drying
Hastelloy and other alloys for corrosive or high-purity applications
Carbon steel for general industrial use

Key features of Nauta dryers

Gentle mixing with low shear action for delicate materials
Conical shape promotes uniform drying and easy discharge
Jacketed for heating and vacuum operation to lower drying temperatures
Closed system minimizes contamination and solvent loss
Compact footprint ideal for batch processing

Dryer- Nauta / Conical FAQ

Have questions about Nauta Dryers / Conical Dryers or our services? Learn more about our products and why customers choose IPP.

Pharmaceutical, chemical, food, cosmetics, and advanced materials industries use Nauta dryers for drying fragile or high-value materials under precise conditions.

Nauta dryers offer gentler, more uniform mixing with vacuum drying, making them ideal for sensitive materials. Paddle and ribbon dryers are more suited to faster, more aggressive drying of robust materials.

Routine maintenance includes inspecting seals, bearings, and drive systems, checking vacuum integrity, cleaning product contact surfaces, and monitoring heat transfer systems.

Buying used from IPP saves up to 70% compared to new, allows faster implementation, promotes sustainability, and provides access to over 47 years of global equipment expertise.
