Fluid Bed Coating

Fluid Bed Coating, also known as fluid bed microencapsulation, is a highly efficient process used for coating granules, powders, and discrete particles in a fluidized bed. This technique utilizes differential airflow to create a cyclic movement of particles, ensuring uniform coating application.

One of the key advantages of this process is the spray nozzle’s bottom location, which allows for controlled agglomeration and efficient coating with minimal material wastage. The result is a uniform film thickness through layer deposition, significantly reducing material consumption and processing time.

This versatile method is used for coating pharmaceutical tablets, softgels, powders, and granules, adapting to various particle shapes including spherical, crystalline, irregular, or amorphous forms.

How Does a Fluid Bed Coater Work?
  • Air Fluidization: Particles are suspended in a chamber by a heated upward airflow.

  •  

  • Coating Application: A spray nozzle applies a fine mist of the coating solution to the moving particles.

  •  

  • Drying Process: Heated air continuously dries the coating, ensuring an even film distribution.

  •  

Layering Control: Multiple layers can be applied for controlled-release formulations.
