Fluid Bed Dryer
Manufacturer of Fluid Bed Dryer
The pharmaceutical industry makes heavy use of fluidized bed dryers to decrease the moisture content of pharmaceutical powders and granules. In order to compress the wet granules into the tablet and alter the properties of the sticky and viscous material, drying is a must. Because its operating principle is so targeted on drying the materials without altering their physical properties, FBD can remove surplus moisture from a variety of materials. Prior to compression into tablets and packaging, drying is usually the final step in the unit process.
Process Operation
As a first step, hot air is forced through the material as it is being fed onto the trembling steel bed. By coming into contact with each particle in the material bed, the high-pressure hot air flow fluidizes the bed. For materials that are particularly sticky or wet, the dryer’s ability to regulate the airflow along its length allows for optimal fluidization. The material will gradually lose moisture as it passes through, until it reaches the desired dryness. Upon reaching the required level of dryness, the material is transferred to a cooling zone. This step involves exchanging the hot air for the cold air that brought the temperature down to the desired level.
