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