Fluid Bed Dryers and Coolers

Fluid Bed Dryers and Coolers Heyl Patterson Fluid Bed Dryers and Coolers

Heyl Patterson Thermal Processing manufactures some of the largest and most efficient Fluid Bed Dryers in the world for free-flowing materials such as minerals, chemical, plastics, hemp & wood products, grains and waste. Materials are suspended in a rising flow of air or gas using an energy efficient fluidizing method that causes the material to act like a fluid which provides a high rate of heat transfer while gently handling the solids. It also provides lower capital equipment and operating costs as a result of its efficiencies. Offered in three types, Trough-Type Fluid Bed, Circular Type Fluid Bed, and Vibrating, each unit can incorporate a standalone or integral cooler to reduce the material temperature after drying.


We also offer Rotary Dryers & Coolers and Flash Dryers & Coolers for our customer’s other specifications.

Specifications for a Fluid Bed Dryer can be customized to a customer's particular application, including:

  • Cylindrical design for back-mix flow, or rectangular design for plug flow
  • Fluidized-media design for sticky, lumpy or otherwise hard-to-handle materials
  • Sizes up to 18 feet in diameter, or equivalent rectangular configuration
  • Inlet gas temperatures up to 2200 degrees F (1200 degrees C)
  • Stainless steel or high-temperature alloy bedplate, or refractory brick dome design
  • Variety of control systems available, from burner management only to complete PLC-based process control

Fluid Bed Dryers are the perfect equipment for processing:

  • Coal
  • Coke
  • Dried Distillers Grains (DDG)
  • Metallurgical Ores
