About the QUEST FB I
The QUEST FB I is a laboratory-scale fluid-bed (FBC) system designed for safe, precise pharmaceutical feasibility studies. It integrates top-spray granulation and Wurster coating capabilities on a compact mobile platform. The unit features a certified 12-bar pressure shock-resistant design and a proprietary Schlick dual-purpose spray nozzle compatible with both top-spray and Wurster processes. Footprint approximately 1 m x 1.2 m, optimised for laboratory environments.

Applications

• Drying
• Wurster coating (pellet coating)
• Top-spray granulation
• Hot-melt granulation

Features & Benefits

• MOST™ concept with a certified 12-bar pressure shock-resistant, non-vented, fully contained design ensuring operator and environmental safety.
• Proprietary Schlick dual-purpose nozzle for both top-spray granulation and Wurster pellet coating, eliminating the need for nozzle changes.
• Heating system with face and bypass mechanism for rapid and accurate process-temperature control.
• Expansion chamber with 360° sight glass for continuous visual monitoring of fluidisation.
• Integrated peristaltic pump controlled via HMI for precise spray-rate management.
• Mobile trolley platform with approx. 1 m x 1.2 m footprint for laboratory space efficiency.
