Static fluid bed


  • processes: drying, cooling,
  • chemical industry: fertilizers, PVC, PP, PE, nylon, urea,
  • food industry: salt, sugar, soya-bean and sunflower proteins, lactose, yeast,
  • mineral industry: sand, lime, aluminum oxide.



  • possibility of drying (usually 2 sections with different temperatures) and cooling in 1 apparatus (3rd section),
  • fluid bed is held by a stream of hot air/gas flowing through a perforated plate,
  • drying temperatures of up to +400 C, moisture content of 30/50% depending on the type of product being dried,
  • possibility of independent operation or in combination with a rotary drier (final drying) or fluidal vibration dryer (difficult product),
  • drying with hot air heated with steam or heating oil or direct drying with gases from a  burner (temperature-resistant products),
  • defined time of stay,
  • dumping of product after drying/cooling through a dumping,
  • no mechanical destruction of crystals,
  • air dedusting system, possibility of its recirculation to the system,
  • preservation of material’s physical and biological properties,
  • high drying/cooling efficiency,
  • fluidization surface up to 32 m2,
  • High-temperature vibratory fluid bed:
    • drying temperatures above 400oC,
    • fluid bed is held by a vibratory platform made of flexible blades,
    • heat exchange in the bed during transverse flow,
    • flow of air up to 24 m/s,
    • recommended in case of gases for cogeneration purposes (energy and heat),
  • Fluid bed with internal heat exchanger:
    • used for drying dusty materials,
    • small flows of hot air for maintaining bed which limits dustiness of exhaust air,
    • diaphragm heat exchange (up to 95%) through internally mounted, in bed, plates heated with water vapor or hot water; also in cooling section.
