The Torusdisc® dryer/heater/cooler is an indirect heat exchanger, with mechanical agitation of material. This indirect heating and drying system provides batch or continuous indirect heating, drying, cooling or reaction of solids, slurries, gels, filter cakes, powders, and viscous materials.

The Torusdisc® processor consists of a stationary horizontal vessel containing a tubular rotor with vertically mounted double-walled discs. These discs provide approximately 85% of the total heating surface. Other heating surfaces are the rotor shaft and the inner wall of the jacketed vessel trough.

During operation of this indirect heating and drying system, a high relative velocity between the rotating discs and the product contributes to a high heat transfer coefficient. Agitator plows or scraper bars can be added to increase exposure of new surfaces and prevent material build-up on surfaces. These design features allow the Torusdisc® to achieve heat transmission-coefficients two to six times greater than many other indirect dryers. Its rotor speed can be set for optimum heat exchange and thorough mixing, independent of residence time. Residence time ranges from minutes to several hours, making the Torusdisc® more versatile than almost any other indirect heat exchanger available today.
