Static fluid bed

Manufacturer: Comspain S.A.

Application:

• 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

Specification:

• 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 400 C
  • 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
