The Fluid Bed Dryer's Operation
What are the workings of a fluid bed dryer? The fluidization concept governs the entire operation of the dryer's full bed. Passing hot gas through wet grains or particles is what this principle is all about. Moisture in the granules is carried away by this ascending vapor. The granules become suspended in the fluid and lose their original moisture content as the gas velocity increases. An electric motor powers the fan inside a standard fluid bed dryer . Basically, this fan's primary function is to draw air from the surrounding environment into the dryer. This air is heated by passing it via a heating system. Once the moisture has been removed from the granules, the heated air then flows through the bed. Continual vibrations guarantee that all of the moisture is exposed to the hot gas. After passing through the filter and collecting the pharmaceutical grains, the heated air is released back into the atmosphere. In addition, the gas's velocity and temperature can be adjuste...
