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. 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 vaporised liquid is carried away by the drying gasses. Sometimes to save energy, the exit gas is partially recycled.

• High rates of moisture removal due to excellent gas-particle constant which results in high heat and mass transfer rates.
• High thermal efficiency is usually achieved if part of the thermal energy for drying is supplied by the internal heat exchanger
• Lower capital and maintenance cost
• Reduced contact time for drying.
• Ease of control
