How is a fluid bed dryer designed?

Understanding Fluidized Bed Dryer Design

Pressure Drop and Fluidizing Velocity

fluid bed dryer design

This graph provides a clear visual understanding of the principles behind fluid bed dryer design, particularly the fluidized bed dryer. It illustrates the critical relationship between the pressure drop across the product and the fluidizing velocity. Notably, we observe a linear increase in pressure drop for a fixed bed, which then stabilizes once the bed fluidizes. This behavior is key to the design of fluidized bed dryers and varies based on the product’s characteristics—finer, heavier products or those with a higher bed depth will react differently to fluidization compared to coarser, lighter products or those with a lower bed depth. By leveraging this design knowledge, we ensure our dryers are optimized for performance across a range of materials and conditions.

The Thermal Processing Curve

The thermal processing curve depicted here is instrumental in dryer design, showcasing the temperature changes of both the medium and the product during the drying process. The curve highlights a critical phase in the design of dryers—the constant rate period—where the product temperature remains at the wet bulb temperature. This stage is paramount for efficient drying, requiring precise control to ensure that the product is dried evenly without any quality degradation. The dryer’s design must account for these temperature dynamics to achieve uniform drying and optimal energy use, which is particularly crucial in fixed bed and fluidized bed dryer applications.

TEMA Process’s technology is versatile, supporting industries from pharmaceuticals to food production, ensuring product integrity in batch processes and efficiency in continuous operations. Our fluid beds are customizable, with options like static or dynamic configurations and submerged heat exchangers, showcasing our commitment to innovation and client-specific solutions.

The design and flexible settings of the fluid bed system

The design and flexible settings of the fluid bed system (air speed, frequency of shaking transport system, air supply temperature etc.) is done with a fully understanding in regard to the proporties of the material that must be dried. Properties like: Product size, particle size distribution, density, stickiness, specific heat of the product its consistencies, product temperature, etc. The shaking motion improves the fluidization and transport of any material within the fluid bed. The Tema fluid bed dryers are equipped with a special designed wide hood that reduces the airflow velocity. As a result of this velocity drop, gravity takes over and the fluidised product will remain in the dryer.

At TEMA, we specialize in designing and engineering tailor-made solutions that serve a broad range of industries. Our focus is on creating fluid bed dryers that are meticulously adapted for the specific products our customers need to process. Each unit is thoughtfully crafted to align with the material’s distinct drying requirements, ensuring optimal performance, efficiency, and product integrity. With TEMA, clients receive a drying solution that is precisely attuned to their operational demands and processing goals.

A fluid bed is an effective unit to thermally treat powders, crystalline products, pelletized or extruded materials. High heat and mass transfer are obtained as a result of the intimate contact between fluidizing air and product.

Shaking fluid bed

units for continuous operation and suitable for sticky materials with a wide particle size distribution. The shaking motion improves the fluidization and transport of any material within the fluid bed. Drying gas temperature up to 750 °C and product temperatures up to 400 °C are achieved

Static fluid bed

Static (non-shaking) fluidised bed or fluid bed

units in continuous and batch type for more uniform materials that do not tend to agglomerate. It is possible to install submerged heat exchangers in a deep static bed. With submerged heat exchangers energy input is both from the fluidizing air as well as from the heat exchangers reducing the size of the equipment and limiting the exhaust air volume.
