For efficient, indirect drying of bulk materials, rotary steam tube dryers deliver exceptional performance across multiple industries. With more than 47 years of expertise, IPP has built the world’s largest inventory of used process equipment, housed at 20 complete plant sites and featuring 15,000+ ready-to-ship pieces. Our inventory includes high-quality used rotary steam tube dryers, allowing you to save time and capital compared to buying new.
Rotary steam tube dryers are designed for indirect drying, using steam-filled tubes that line the interior of a rotating drum. Heat transfers from the steam through the tubes into the product, gently evaporating moisture without directly exposing the material to combustion gases. This design makes rotary steam tube dryers ideal for heat-sensitive materials or processes requiring precise temperature control.
These dryers excel at processing:
To match diverse process requirements, rotary steam tube dryers are available in:
