Fluid Bed Dryer parts - RAVI INTERNATIONAL fluid bed dryer parts

The Ravi international – Fluid bed dryer parts are as follows.

Ravi International offers Fluidized bed dryer (also called fluid bed dryer) is a kind of equipment used extensively in the pharmaceutical industries to reduce the moisture content of pharmaceutical powder and granules. The equipment works on a principle of fluidization of the feed materials. (watch video).

A typical fluidized bed dryer consists of the following components

a. Air preparatory unit.

b. Product container.

c. Exhaust filter.

d. Exhaust blower.

e. Control panel.

f. Air distribution plate.

g. Spray nozzle.

h. Solution deliver.

In fluidization process, hot air is introduced at high pressure through a perforated bed of moist solid particulate. The wet solids are lifted from
the bottom and suspended in a stream of air (fluidized state). Heat transfer is accomplished by direct contact between the wet solid and hot gases.
The vaporized liquid is carried away by the drying gasses. Sometimes to save energy, the exit gas is partially recycled.

Ravi International also manufacture other dryer such as Rotocone vacuum dryer, Rotary Vacuum paddle dryer, Vacuum Tray Dryer, Agitated nutsche filter dryer
