How does a fluid bed granulator work?

Introduction

The fluid bed granulator is an essential component in the pharmaceutical, food, and chemical industries. It offers efficient granulation, which is crucial for material processing. Understanding its operation enhances optimized usage and maximized output.

Principles of Fluid Bed Granulation

Fluid bed granulation involves suspending particles in a fluidized state while spraying a liquid binder. As particles interact, they form granules upon drying. This process ensures uniform mixing and quick drying times, essential for product consistency.

Mechanical and Technical Parameters

The operation of a fluid bed granulator is influenced by several parameters:

• Airflow Rate: Typically ranges from 0.2 to 2.5 m³/min. Optimal airflow ensures proper fluidization without particle elutriation.
• Inlet Air Temperature: Maintained between 60°C to 120°C. This controls the drying rate and affects the granule size.
• Spray Rate: Varied between 5 to 25 ml/min. Determines the liquid distribution and subsequent granule formation.
• Nozzle Position: The nozzle must be positioned to allow even binder distribution, influencing the granule size and uniformity.
