Fluidized bed processing: A review

The formulation development is the key step in the success of a formulation to sustain in the present day market. Such formulation development is emerging new technologies for the development of products via innovative techniques, of which Fluid Bed Technology is one important and successful technique widely being used in the pharmaceutical industries now-a- days. This review article discusses about the principle involved in fluidized bed processor (FBP) and the latest equipment available in market working on the principle of FBP. The main principle involved in the FBP is the air suspension in which the material to be coated is suspended in the coating material with the help of air stream. Fluid bed process involves three principles viz.,. top spray, bottom spray and tangential spray. Detailed information regarding the advantages, principles and the latest technology involved in the FBP is discussed in separate sections under this review. Some of the current issues faced and the troubleshooting of such methods were also described. The FBP has a wide range of applications such as drying, granulation powder or particle coating and pelletizing.
