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
