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
  • Plastics
  • Rubber
  • Hemp & Biomass
