The blower situated on the exhaust side of the dryer operates no negative pressure principle, which creates the induced draught and sucks in the fresh air into the dryer. A stream of hot filtered air is introduced from the bottom of the product container containing the wet material. This container is provided with the air distribution plate and Dutch sieve. The air stream is passed through the bed of the material and fluidizes the product particles by creating turbulence in the product container. Due to fluidization, each particle gets surrounded by hot air, which leads to quick & uniform heating and drying. Filter bags provided at the top prevent escaping of particles from the machine.

Fluidized Bed Dryers Provide Rapid and Even Drying
The incoming hot gas/air has a velocity larger than the settling velocity of the particles. This results in the particles being dispersed in the heated gas or air.
This fluidized condition allows for direct contact between the hot gas or air and the particle you need to dry. As a result, drying may be completed in 10 to 40 minutes.
The fact that every particle of the solid is surrounded by heated air or gas assists with equal drying.
The basis of operation is the same whether you choose a horizontal or vertical fluidized dryer.
Heat Sensitive Products Can Benefit from Fluid Bed Drying
The degradation of certain powders and granules occurs when exposed to high temperatures. Conventional drying methods are ineffective for these items.
During the drying process, new fluidized bed designs include sophisticated sensors that keep tabs on a wide range of critical variables.
It is possible to manage the quality of the final product despite the high rate of mass and heat transmission.
The temperature and airflow settings may be conveniently monitored using the control panel. In other words, using today’s control systems, you can regulate all of the incoming airflow characteristics.
Designs for Rapid dryers, Various Sizes, and Capacity Options
Rapid dryer can be used in a variety of industries, including pharmaceuticals, laboratories, and R&D facilities.
There are no hot spots on the finished products.
A hot spot can be found on virtually every piece of drying equipment. This is because the surface that is doing the drying is in direct contact with the items that are being dried.
In the drying chamber, all of the materials are held aloft while they are being dried. You also have the choice to go with a quick drier that has a capacity that ensures the particles and the air are thoroughly combined with one another. This is an additional available choice.
When drying products using alternative methods, you should never use high heat because it could potentially ruin the product. However, you are able to use high drying temps with the quick dryer if you so choose.
Because of the distinctive method by which the quick dryer accomplishes its drying tasks, it can also be used to dry goods that are sensitive to heat. Because of this, fluidization is a common and widespread process in the pharmaceutical sector. It is also a popular activity.
