Heated Screw Conveyor | Thermascrew

Thermal Screw Conveyor

The Bepex Thermascrew is a jacketed screw conveyor offering high heat transfer surface area. Both the vessel walls and conveying rotor are jacketed and can be thermally conditioned using a variety of media, including steam, hot thermal oil, chilled glycol or water. It provides gentle uniform heating, cooling, evaporation, and roasting. Slow rotating screw(s) protects fragile materials from breakage typically seen in other mechanical dryers.


  • Full heat transfer surface utilization with heated vessel and rotor
  • Gentle conveyance and mixing protect material from breakage providing consistent heating or cooling
  • Plug-flow operation providing controlled, narrow residence time distribution
  • Single or multiple screw designs to provide additional surface area in a compact footprint
  • Application versatility means you can heat or cool liquids, slurries, powders, or granules

Heat transfer media is introduced and flows through both the vessel walls and the rotor. The media enters the rotor via a rotary joint, moving through the hollow screw for increased thermal surface area. Feed material enters via an inlet port and is gently conveyed while it is thermally treated, minimizing any material breakage. Both residence time and product temperature are strictly controlled ensuring a consistent product.

The Thermascrew heated screw conveyor is just one of the thermal technologies we employ to develop industrial process systems that meet your application requirements. At Bepex, we are committed to developing the best thermal process systems using the right technology. Between our proven industrial process equipment and decades of experience serving the industry, we are able to design a thermal screw conveyor that is right for you.
