A Fluid Bed Dryer (FBD) is a piece of industrial equipment used to dry granules, powders, or crystals by passing hot air through them in a fluidized state. It’s commonly used in pharmaceutical, chemical, and food industries.

Let’s break it down 👇

🔧 Working Principle

The Fluid Bed Dryer works on the principle of fluidization:

Hot air is passed through a perforated plate at the bottom of the dryer.

The airflow lifts and suspends the particles, making them behave like a fluid.

The heat from the air evaporates moisture from the material.

The moist air exits through filters at the top, leaving behind dried granules.

⚙️ Main Parts

Air Handling Unit (AHU) – Heats and filters the air.

Product Container (Bowl) – Holds the wet material.

Perforated Plate – Distributes air evenly.

Filter Bags – Prevent powder from escaping with air.

Blower Fan – Creates upward airflow.

Exhaust Duct – Removes moist air.

🌡️ Process Steps

Loading – Wet granules are loaded into the bowl.

Drying – Hot air passes through the material; moisture evaporates.

Moisture removal – Air carries away the evaporated water.

Cooling – After drying, cool air is passed.

Unloading – Dried granules are discharged.

📈 Advantages

Fast and uniform drying

Efficient heat and mass transfer

Short drying time

Easy to clean and operate

Suitable for heat-sensitive materials

⚠️ Disadvantages

Not suitable for very fine or sticky materials

Requires uniform particle size for proper fluidization

Higher initial cost

🧪 Applications

Drying wet granules after wet granulation in pharma manufacturing

Drying food powders, detergents, and fertilizers

Coating particles (in modified FBDs)
