Rotary vacuum dryers are indirect batch dryers designed for efficient moisture removal under vacuum conditions. They’re ideal for temperature-sensitive products, solvent recovery, and materials that require precise control during drying. With over 47 years of experience, IPP offers a wide inventory of used, secondhand and surplus rotary vacuum dryers from 20 global plant sites and more than 15,000 ready-to-ship systems. These units combine heat transfer efficiency with controlled environments, helping manufacturers reduce drying times while protecting product quality.
The rotary motion improves contact between the material and the heated wall of the jacketed vessel. Combined with vacuum pressure, this design reduces the boiling point of moisture or solvents, making it ideal for thermally unstable or hazardous materials.
These dryers are designed for cleanability, corrosion resistance and precise thermal control:
