Industrial Disc Dryers | TorusDisc

Paddle Dryer

The TorusDisc paddle dryer provides maximum heat transfer area in a compact footprint. A series of rotating, thermally conditioned discs provide the perfect combination of heat transfer and material agitation for indirect thermal treatment of your material. Longer residence times are available as determined by an adjustable discharge weir, making this technology suitable for drying down to PPM moisture levels. Residence times are independent of rotor speed, making the TorusDisc suitable for handling cohesive materials or difficult transition phases in drying operations.


  • Adjustable paddle, bed-type dryer
  • Gentle drying and mechanical agitation of material yields minimal dust generation
  • Compact footprint with maximized heat transfer area
  • Dual intermeshing rotor design utilized when handling cohesive feed materials
  • Natural back-mixing at the feed inlet helps improve drying and prevents sticking
  • Able to operate under vacuum or pressure for your more specialized drying needs

Feed material, whether wet solids, liquids, pastes, or slurries, enter via the material inlet. The rotating discs begin agitating and conveying material throughout the machine while heating or cooling the bed of material. Stationary plows or breaker bars can be mounted in-between the discs to provide additional resistance and break apart any cohesive forms, ensuring more efficient drying. An adjustable weir at the discharge establishes bed height and residence time, allowing the rotor speed to operate independently from residence time. The TorusDisc has been used in a variety of industries and applications, from drying silica gel and clay, to crystallizing plastics. Models range from several hundred kilograms to tens of tons per hour. Operational versatility allows for heating/cooling, drying, reacting or crystallizing your material.
