Fluidized bed dryer FSD®

sprayingdryingfor the food industry

Uniform coarse, agglomerated, free-flowing and dustless powder is in strong demand in most industries. The FSD™ Spray Dryer is the ideal choice for such production The FSD® Spray Dryer, combining spray- and fluid-bed drying, is designed to provide optimum drying efficiency and the best product quality in agglomerated powders. The design, specific to the different industries, has gained worldwide recognition among producers of a wide range of food products and chemical compounds. The FSD® Spray Dryer operates with three drying stages, each adapted to the moisture content present during the spray drying process. The liquid feed is atomized and fed into the drying chamber by a set of nozzles. The drying air enters vertically, and at a high velocity, through the air disperser, thus ensuring optimal mixing with the atomized liquid. Evaporation takes place instantaneously while the droplets pass through the drying chamber. The drying chamber and air flow have been designed to prevent particles from sticking to the chamber walls, leading them directly to the integrated Fluid Bed at the bottom of the drying chamber where the second drying stage will take place. Finally the powder is led to a VIBRO-FLUIDIZER® Fluid Bed for the final drying and cooling.
