Thermal Screw Conveying Equipment

Heating and cooling jackets for thermal processing can be integrated on Twin Screw, Tubular, and U-Trough Conveyors.

Features & Benefits

Thermal treatment occurs in the conveyor during the conveying cycle to eliminate secondary process steps and unnecessary additonal equipment.

Independent jacket configuration allows a parallel feed of fluid to each jacket panel where product is always exposed to a fresh temperature cycle.

Indirect heat transfer design often does not require air filtration or exhaust permits like direct heating methods.

Control of temperature during material transfer for maximum efficiency.

Accurate control of thermal treatment time ensures precise requirements are met.

Greater heat transfer surface area per unit of product than batch mixer systems.

Proprietary design delivers increased efficiency with a smaller footprint as compared to traditional conveyor designs.

High efficiency auger design features rotary unions to flow fluid through the auger itself to maximize the amount of product that has direct contact with the heat transfer surfaces and minimize the formation of deep, untreated product beds.

Auger features a chain drive and adjustable speed design to economically achieve the slower speeds necessary for varying heating and cooling processes.

Auger shaft seals are typically packing gland style seals that provide a wide range of temperature and chemical compatibility.

Designs for high pressure applications that meet the requirements of the ASME Boiler and Pressure Vessel Code.

Sample Applications

Heating and cooling screw conveyors are used around the globe for thermal processing in industries such as biomass conversion, paper and pulp, biofuels, food and dairy, chemicals, petrochemicals, minerals processing, and many more.
