MICROWAVE AND ITS ROLE IN PHARMACEUTICAL SECTOR: A REVIEW
Energy is supplied directly to the material by an electromagnetic field in the processing of microwave. Due to this rapid heating takes place throughout the material thickness with reduced thermal gradients. Volumetric heating can also reduce processing times and save energy. The microwave field and the dielectric response of a material govern its ability to heat with microwave energy. Knowledge of electromagnetic theory and dielectric response is necessary to optimize the processing of materials through microwave heating. The fundamentals of electromagnetic theory, dielectric response, microven and its advantages, especially applications of microwave in Pharmaceutical, are reviewed in this article.
