Twin shell and double cone dryers are rotating batch dryers used for low-shear, uniform drying of powders, granules and crystalline materials. Their simple, sealed design makes them ideal for vacuum drying and mixing sensitive or friable compounds. With over 47 years of experience, IPP offers a large inventory of secondhand and surplus twin shell and double cone dryers from 20 complete plant sites and more than 15,000 ready-to-ship systems.

These dryers operate by rotating the vessel to gently tumble the product while applying indirect heat through a jacket. Vacuum can be applied to reduce drying temperature, which is especially valuable for thermally sensitive materials or solvent removal.

Primary uses across industries

In pharmaceutical production, they dry APIs, intermediates and fine powders without degrading the product
In chemical manufacturing, they process specialty powders, pigments and sensitive catalysts
In nutraceuticals and food, they’re used for vitamins, proteins, extracts and granular ingredients
In plastics and resins, they dry additives and heat-sensitive compounds

Types of materials processed

Heat-sensitive powders and granules
Free-flowing solids requiring gentle tumbling
Products containing residual solvents

Common materials of construction

These dryers are built for corrosion resistance, cleanability and safe operation under vacuum:

Stainless steel for pharmaceutical and food-grade use
Carbon steel for non-corrosive industrial products
Specialty alloys like Hastelloy for reactive or high-purity applications

Key features of twin shell and double cone dryers

Gentle tumbling motion for uniform drying
Vacuum-compatible for low-temperature operation
Low shear – preserves fragile particles and blends
Sealed environment minimizes contamination
Easy to clean and maintain, with minimal moving parts

Dryer-Twin Shell & Double Cone FAQ

Have questions about Twin Shell & Double Cone Dryers or our services? Learn more about our products and why customers choose IPP.

Both function similarly, but twin shell dryers feature V-shaped vessels while double cone dryers have a symmetric conical design – the choice depends on capacity, layout and material flow needs.

They offer clean, low-shear, enclosed drying that prevents cross-contamination and protects sensitive materials.

Regular inspection of seals, vacuum connections, and vessel rotation systems is key to ensuring performance and product integrity.

IPP provides faster lead times, deep cost savings, and 47+ years of global expertise to help clients scale efficiently.
