Here’s how it really works: The material to get dried is placed inside a bed, and sizzling air is blown from underneath.

The drying approach requires area in 3 stages until eventually the top level is arrived at (At the tip level the strong particles dampness stage is equivalent or under one%)

This permits for successful heat transfer and uniform drying as being the particles are frequently in movement. The hot air passing from the bed carries away humidity within the wet content, causing fast and powerful drying. Fluidized Bed Dryers are commonly Employed in various industries for drying granular and powdered materials.

Inlet air is blown up with the static electricity mattress as being the velocity of your air improves so does the Room among powder particles until the particles come to be suspended inside of a mattress the fluidization method is through to manifest in 5 levels like sleek  fluidization, bubbling  fluidization, turbulent fluidization and very first  fluidization.  

Just before opening the valve of potable drinking water make sure right connection of both of those ends here of pipe is done properly.

It's the Element of FBD that is movable and includes products which is required to be dried. Right after damp sieving of granules, granules are added to the product or service trolley and item trolley is sealed in excess of bowl of FBD from the drying chamber. 

The sucked air passes via a number of filters where by particles and impurities are taken off. The filtered air then proceeds to pass through a heating program exactly where it’s heated to the desired temperature with regards to the product’s requirements.

 From the fluidization system, warm check here air is launched at high strain via a perforated mattress of moist good particulate. 

The fluidized mattress dryer contains a stainless-steel chamber possessing a detachable perforated underside known as the bowl.

1. The wet granules being dried are put in the detachable bowl. The bowl is pushed in to the fluidized bed dryer.

Since the move of air boosts, the mattress expands and particles of powder begin to rise up in a very turbulent movement.

This Management makes it possible for operators to tailor the drying procedure to particular material needs, optimizing the overall performance on the operation.

This air stream leads to the particles to become floating, resembling a fluid, therefore the term “fluidized.” As a result, Just about every particle is surrounded by scorching air, resulting in immediate and uniform drying.

Switching the blower unit on is done from the control panel. When the blower is operational, the air is drawn continuously through the Air Handling unit and in the tower with the reduce plenum.
