GFG Series High-Efficiency Fluid Bed Dryer | Pharmaceutical & Food Granule Drying

The Unitfine GFG High-Efficiency Fluid Bed Dryer is a vertical batch drying system engineered for the rapid and uniform dehydration of powders and granules. Designed specifically for the pharmaceutical, food, and chemical industries, its round structure eliminates dead corners, ensuring easy cleaning and full GMP compliance.

The machine operates by passing purified hot air through a distribution plate, creating a "fluidized" state where wet materials are suspended for maximum heat transfer efficiency. Featuring negative pressure operation and an anti-static bag filter, the GFG Series ensures a safe, dust-free, and highly efficient drying process suitable for damp granules and screw-extruded particles.

Pharmaceutical wet granules being dried in fluid bed dryer des

Product Introduction :

The GFG Series is a high-efficiency vertical fluid bed dryer tailored for the pharmaceutical, food, and chemical industries. Unlike traditional horizontal dryers, its round structure prevents dead corners, making it easy to clean and fully GMP compliant.

How It Works 

Purified heated air is introduced from the bottom via a suction fan. The airflow passes through the screen plate, creating a ‘fluidized’ state where wet granules are suspended in the air. This ensures maximum contact surface for rapid moisture evaporation.

Key Features :

  • No Dead Corners: The circular bed design prevents material buildup.

  • Uniform Drying: Consistent temperature distribution ensures no overheating or uneven moisture.

  • Safety Operation: Operated under negative pressure to prevent dust leakage; equipped with pressure relief holes for safety.

  • Efficient Filtration: Multi-chamber bag filter catches fine dust effectively.
