The Fluidized Bed Dryers are used extensively in the pharmaceutical industry to reduce moisture content of powder and granules in a drying process.
This process equipment works on a principle of fluidization of the feed materials. In the fluidization process, hot air is introduced at defined pressure and flow rate through a perforated bed of moist solid particles. The wet solids are lifted from the bottom and suspended in a stream of air (fluidized state).
Heat transfer is accomplished by direct contact between the wetted solid and hot gases. The vaporized liquid is carried away by the drying gasses.
STE TECPHARM offers a wide range from R&D to industrial sizes of Fluidized Bed Dryers with also the possibility of Granulation with Top Spray and Coating by means of Bottom Spray.
