In the context of a fluidized mattress dryer, this result is obtained by passing hot air or gasoline through a mattress of raw components, which will cause the particles to behave just like a fluid.
The principle driving a Fluidized Bed Dryer revolves across the idea of fluidization. Fluidization is a method through which strong particles are made to behave like a fluid by passing a gas or liquid through them.
Technically, it comes about when the drag pressure of a fluid upward is balanced because of the gravitational drive of your good particles. These particles are suspended during the fluid, creating a fluidized or suspended strong bed.
Over-all, while the fluidized mattress dryer is actually a powerful piece of kit in drying procedures, certain constraints needs to be deemed before their implementation.

The dried item is then discharged within the dryer. The fluidized bed dryer is made this kind of that the air velocity lessens in direction of the top with the drying chamber.
If air is permitted to movement by way of a mattress of strong powdered substance within the upward course Using the velocity increased compared to settling charge of your particles, the stable particles is going to be blown up and come to be suspended from the air stream.
The bags used here Have a very finger-like composition which aids boost the surface area on the drying bed. This type of design and style allows raise the drying amount and reduce get more info the drying time during the fluid bed drying approach.
In these dryers, the fluidized mattress is subjected to vibrations, which assist in better Make contact with involving the drying medium and the fabric. This enhances heat and mass transfer, resulting in speedier and a lot more uniform drying.
The decrease aspect of product trolley is fitted by using a perforated base. In some FBD going or rotating rods are attached which rotate after some time intervals and forestall the Develop-up of regional mass development.
Any time a drive is at first drawn, its duration may well not suggest the magnitude. Its line may not correspond to the precise line of motion. Even its orientation is probably not suitable.
Numerous portions of the fluidized mattress dryer Engage in integral roles in this method. The distributor plate, For illustration, is essential for distributing the heated air uniformly over the mattress of fabric.
The price of a fluidized mattress dryer can vary tremendously dependant upon Potential, Substance of development and additional characteristics like temperature Regulate devices, dust collectors, and explosion-proof building can add to the fee.
