The fluidized mattress delivers a really perfect setting for heat and mass transfer due to its high floor space and efficient mixing. As the particles are suspended and agitated, the drying or granulating medium can penetrate the mattress, swiftly transferring heat on the particles and evaporating dampness.
A lover is offered at the best on the circulating very hot air. Refreshing air enters; filters and heat Trade are linked serially to warmth the air for the required temperature.

We validate the worth of reduction on drying for every merchandise. Normally, one to three% LOD is necessary for almost all of the manufacturing but it could differ based on the character of the product or service.
Vibration and passive acoustic emission measurements are influenced from the bed hydrodynamics. Nevertheless, mattress actions for instance large particle entrainment prices and weak fluidization ailments related to major and here wet granules might be evaluated from your measurements. This allows bed hydrodynamic data to be incorporated in optimizing the method and endpoint dedication.
This condition is generally known as fluidized point out. Each and every granule is extensively dried via the as, which envelops them.
Effectiveness: FBDs are energy-productive because of their successful warmth transfer along with the recycling of warm air in the system.
