Static fluid bed dryer for powder and granular materials
When dealing with powder, crystalline, or granular materials, removing surface moisture and bound moisture can be a significant challenge. Technologies that ensure consistent moisture levels while maintaining the material’s integrity are crucial in such scenarios.
Ensures efficient drying with optimal heat transfer
The Static Fluid Bed Dryer from GEA operates by using a fluidizing gas to create a cushion of air or gas that supports the material, creating a fluidized state. This state facilitates high heat and mass transfer rates, ensuring effective moisture removal. The design includes a perforated distributor plate that ensures even distribution of the fluidizing gas, preventing carry-over of very fine materials to the dust collection equipment. It supports a high turndown ratio and can absorb feed rate fluctuations. This dryer can be customized with several design variations, including stirred, deep, and high-temperature fluid beds, as well as multiple zones and stages. The system can offer thermal efficiency up to 90% with optional contact heat exchange tubes. Practical applications include processing powders, chemicals, and other granular materials across industries requiring precise moisture control.
