For drying heat-sensitive materials while preserving product quality, rotary vacuum dryers provide a trusted solution for industries requiring gentle, low-temperature moisture removal. With over 47 years of experience, IPP has built the world’s largest inventory of used process equipment, spanning 20 complete plant sites and 15,000+ ready-to-ship pieces. Our selection of used rotary vacuum dryers delivers cost-effective performance without the delays of ordering new equipment.
Rotary vacuum dryers operate by placing the product inside a sealed rotating drum under vacuum, significantly lowering the boiling point of moisture. Indirect heat is applied to the drum’s walls, gently evaporating moisture while protecting sensitive materials from thermal degradation. The rotating motion ensures uniform drying and prevents clumping, making rotary vacuum dryers ideal for pharmaceuticals, fine chemicals, and specialty food products.
Industries and materials that rely on rotary vacuum dryers include:
Rotary vacuum dryers are built to withstand demanding processes and stringent sanitary requirements, with typical materials including:
