Pharmacy Fluid Bed Processor

1 Drying and mixing

The fluidized state described earlier provides an ideal platform for drying and mixing in fluidized beds. By adjusting parameters such as air temperature, air volume, and air pressure at the inlet, the product can be thoroughly dried and mixed. Additionally, a CFR audit tracking system can be optionally installed to record data from each drying and mixing cycle, enabling compatibility with various materials.

2 Granulating

This technology is based on the modular design of the FBM produced by Senieer. The granulation process is achieved by replacing the spray chamber (typically using the top spray method for granulation) and the raw material container. In the fluidized state, the liquid is introduced into the system through pneumatic nozzles installed in the spray chamber. The atomized liquid should cover the maximum flow range of the material as much as possible to ensure a concentrated particle distribution.

3 Coating

The coating process requires a change in spray method to bottom spray. A partition ring with openings at both ends and corresponding sieve plates with different aperture rates are added to the hopper to fluidize the material and distribute it around the Wurster column. The material then re-enters the central area from the bottom of the column to control its movement and form an orderly fluidized state. Liquid is introduced into the system through pneumatic nozzles installed at the center of the sieve plates, with its direction aligned with the material’s movement. This ensures uniform and continuous coating film formation, which is a critical factor in sustained-release formulations. The spray droplets travel short distances, resulting in reduced solvent consumption for coating.
