Since 1982, drying technology based on the fluid bed system has been setting the standards in terms of

• Safety
• Simplicity
• Reliability

Fluid Bed

The fluid bed is generated by blowing fluidization gas uniformly over the dryer cross-section. The free-flowing granulate in the dryer begins to float and is at the same time mixed thoroughly. A fluid bed is characterized by movement of the granules, achieved by a gas stream passing through the product layer.

Features

• direct sludge feed structures the granulate from the start
• dry product addition is not necessary
• the physical properties of the fluid bed result in a virtually dustfree final product
• low drying (product) temperature
• indirect heat supply via heat exchanger in the fluidized bed
• various heat sources may be used, e.g. thermo oil, steam, waste gas, etc.
• Product is treated in an inert atmosphere only (<3% O2), ensuring a high safety standard for the entire drying system
• Good environmental compatibility is ensured due to
  - closed, gas-tight construction
  - low off-gas quantity from drying process
  - low odour emissions

Advantages

• operating time 24 hours per day, seven days per week
• over 8,000 operating hours per year
• operation is possible without presence of personnel
• low repair and spare parts costs because there are no moving parts in the drying system
