Types and Features of Fluidised Bed Dryers
Fluidized bed is achieved by passing a gas stream from the bottom of a bed of particulate solids. At low velocity of gas the bed stays in static condition, and the particles lay on a gas distributor plate. The fluidizing gas passes through the distributor and it is uniformly distributed across the bed. The gas velocity is increased such that to achieve the fluidization of bed, gas velocity at which the bed achieves the fluidization is known as minimum fluidization velocity. A Fluidised bed dryer operates at gas velocity higher than the minimum fluidization velocity of material under processing. This increase in the gas velocity result in suspension of particles under processing in air, this appears as the boiling of solid particles of material under processing.

Both rotary dryers and fluid bed dryers are widely used in chemical processing, but their suitability depends on the material properties. Rotary dryers are better for granular, lumpy, or abrasive materials that can tolerate mechanical contact and longer residence times. Fluid bed dryers are ideal for free-flowing, uniform-particle-size materials that benefit from excellent gas-solid contact and faster drying rates. Kerone offers both systems, with fluid bed dryers providing better control over product temperature and moisture uniformity, making them preferred for fine or heat-sensitive chemicals.
Minimum fluidization velocity is the gas velocity at which a bed of particulate solids transitions from a static, settled state into a suspended, bubbling condition that resembles a boiling liquid. Below this velocity, the bed behaves like a packed solid with poor gas-particle contact, while operating at or above it is what enables the excellent heat and mass transfer fluidized bed dryers are known for. Setting gas velocity too far above minimum fluidization risks excessive particle carryover into the exhaust and increased erosion, while running too close to the minimum risks incomplete fluidization in parts of the bed. Kerone calculates this velocity based on the specific particle size, density, and shape of each material before finalizing the design.
Fluidized bed dryers are generally most effective for particle sizes in the range of roughly 10 to 2000 microns, where particles are light and small enough to be readily suspended by a practical gas velocity without requiring excessive air volume or fan power. Particles significantly larger or denser than this range need much higher gas velocities to fluidize, which becomes energy-inefficient and can cause excessive wear on the distributor plate and ductwork. Conversely, extremely fine particles below this range risk being carried out of the bed entirely with the exhaust gas before adequate drying occurs, requiring more aggressive downstream filtration. Materials outside the ideal range are often better suited to rotary or flash drying instead.
The distributor plate sits at the base of the bed and is responsible for spreading incoming gas evenly across the entire bed cross-section before it passes upward through the particles. Uneven gas distribution from a poorly designed or worn distributor plate creates channeling, where gas preferentially flows through certain areas while other parts of the bed remain poorly fluidized or even static, leading to inconsistent drying across the batch. Distributor plate design must balance even gas distribution against pressure drop and the risk of particles falling through the plate openings when fluidization is interrupted, such as during startup and shutdown. Kerone's modular design allows the heat exchanger and distributor components to be inspected and replaced without major dryer downtime.
Spray drying atomizes a liquid feed into fine droplets that dry almost instantly in a hot air chamber, producing a fine powder directly from a liquid or slurry in a single step. Fluidized bed drying, by contrast, typically works on material that is already in granular or particulate form, or uses fluidization to dry and sometimes agglomerate wet granules into a more uniform particle size. Kerone's fluidized bed systems can handle granular materials, pastes, solutions, and suspensions in batch or continuous configurations, but the underlying mechanism relies on suspending discrete particles rather than atomizing liquid droplets. The choice between the two often comes down to whether the desired final product form is a fine powder or a more structured granule.
Some products require longer exposure to the drying gas stream than a standard single-pass fluidized bed provides, particularly materials with moisture bound more deeply within the particle structure rather than just on the surface. Kerone's fluidized bed dryers can be configured to provide extended residence times through bed depth, multi-stage chambers, or recirculation arrangements that keep particles in the fluidized state longer without simply running the gas velocity higher. This allows more complete moisture removal for materials with slower internal diffusion rates, without resorting to excessive temperatures that could damage heat-sensitive particles. Buyers with materials known to have slow-release internal moisture should flag this during the design consultation.
