Rotary steam tube dryers use indirect heat transfer through steam-filled tubes, making them ideal for drying materials that are heat-sensitive, combustible or require controlled atmospheres. With over 47 years of equipment expertise, IPP offers a wide selection of used, secondhand and surplus rotary steam tube dryers from 20 complete process plant sites, all backed by an inventory of 15,000+ ready-to-ship systems. These units provide gentle, efficient drying for high-value materials.

Unlike direct-fired rotary dryers, steam tube dryers transfer heat through conduction via rotating tubes filled with steam. This approach protects sensitive materials while allowing continuous, high-capacity operation.

Primary uses across industries

In pharmaceuticals and fine chemicals, they dry active ingredients and intermediates without degradation
In food and nutraceuticals, they gently process starches, proteins, vitamins and botanicals
In polymers and resins, they dry temperature-sensitive compounds safely
In mining and minerals, they process materials that cannot withstand open flame drying

Types of materials processed

Thermally sensitive solids and powders
Combustible or flammable materials
Materials requiring recovery of solvents during drying
Bulk materials where product quality must be preserved

Common materials of construction

Steam tube dryers are built with precise heat transfer and corrosion resistance in mind:

Stainless steel for sanitary and chemical-sensitive applications
Carbon steel for general-purpose drying
Specialty alloys for high-temperature or corrosive processes

Key features of rotary steam tube dryers

Indirect heating for gentle, uniform drying
Steam-filled tubes rotate within a stationary shell
Suitable for vacuum or inert atmospheres
Lower emissions and solvent recovery-friendly
Continuous, automated operation for large-scale needs
