Heating Screws

Heating Screws transfer heat through contact with an external jacket (bolt-on or integral), and/or through the transfer Augers itself. The material is heated or cooled while being tranferred down the length of the Conveyors. In the case of a hollow flight auger, the flights themselves aid in heat transfer. To accomplish this, a variety of heating or cooling media may be used.Heat transfer takes place via screw shaft, jacket, flights or a combination of all.

Heating Screws

Advantages

  • Designs for high pressure applications meet the requirements of the ASME Boiler and Pressure Vessel Code.
  • Cost savings as the thermal treatment is accomplished in the same time as product is conveyed.
  • Accurate control of thermal treatment time.
  • Control of temperature during material transfer.
  • Greater heat transfer surface area per unit of product than batch mixer systems.
  • In-house testing available

Applications

  • Drying
  • Polymerization
  • Heat curing
  • Cooling/freezing
  • Microbial kill
  • Sintering/calcining
