Working of Fluidized bed dryer . A fluidized bed dryer works by passing Hot air with high pressure through a perforated bed of moist solid particles. The hot air passes at a velocity greater than the settling velocity of the particles resulting, particles starting to …
It was found that the fluidization velocity of 2.7 times the u mf, confirmed the bubbling fluidization regime in seeds (Geldart's group-B) drying. The bubbling bed fluid-dynamic regime is being foreseen in FBD and is characterized by the formation of gas bubbles with random mobility of bed particles, and the dead zones are almost disappeared.

Fluidized bed dryer (also called fluid bed dryer) is a kind of equipment used extensively in the pharmaceutical industries to reduce the moisture content of pharmaceutical powder and granules. The equipment works on a principle of fluidization of the feed materials.
With a fluid bed and sub-fluid bed a range of products can be processed which previously could only be processed with a belt dryer. The Ventilex sub-fluid bed has amply proved its quality in processing, among others: cereals, seeds, nuts, beans, croutons, breakfast cereals, cheese, meat, fibers, extrudates, pellets and plastic granulates.
