The FBD method operates around the principle of fluidization, exactly where a bed of solid particles is remodeled into a fluid-like condition by passing a gas or liquid through it.

Times are revealed as curves with an arrow head or even a vector with two arrow heads pointing from the direction they act on your body

Drying time is inversely proportional to your inlet air temperature. The drying speed is dependent upon The interior temperature on the good bed. Air temperature also has an impact on dampness diffusion in drying.

General, when the fluidized bed dryer is often a strong piece of kit in drying processes, unique constraints ought to be regarded prior to their implementation.

During the pre-heating phase, the bed’s temperature was growing but Within this phase, particles keep on being in exactly the same temperature. It's the scenario since any Strength equipped is taken up from the evaporating molecule since the transition on the liquid into the gaseous state.

Mechanical shaking is The easiest way to take out the dust layer and it is completed from the pneumatic cylinder with the set intervals and seems Now we have two filtering chamber the shaking is alternated amongst the two.

Soon after a specific time, a stress issue is attained wherein the friction drag with a particle is equivalent on the drive of gravity.

Horizontal Fluidized Mattress Dryers: These dryers Have got a horizontal drying chamber. They're perfectly-fitted to products which have been easy to fluidize and do not require a superior drying temperature.

Inside the fluidized bed dryer, the particles are particularly suspended in a mobile gasoline stream (Sizzling Air), the air serves as a boiling liquid inside the perception which the particles are first lifted upward then they slide back. This method delivers better warmth transfer and much better mass transfer.

The Original startup move within a fluid bed dryer is to incorporate a clean batch of damp granules on the product or service chamber. The Feeding substance could be sucked within the high shear mixer chamber via a feeding tube beneath adverse strain.

Improved Warmth Transfer: The fluidized condition of your bed allows for enhanced warmth transfer concerning the FBD principle drying medium (normally air) and the fabric getting dried. This economical warmth transfer contributes to lowered drying situations and decrease Electrical power intake, earning FBD a more Price tag-powerful Answer.

Humidity: Quicker drying is accomplished when the dampness information with the inlet air is preserved at its bare minimum.

The price of a fluidized bed dryer could vary enormously depending on Capacity, Content of design and extra features like temperature Manage techniques, dust collectors, and explosion-proof building can incorporate to the fee.

The dryer is usually divided into several different zones with independent check here Charge of airflow and temperature so that drying can happen at the maximum desirable rate in Every stage without sacrificing performance or harmful warmth-sensitive supplies.
