The Fluidized Spray Dryer (FSD?) combines spray drying and fluid bed drying technologies and offer excellent product flexibility and excellent thermal efficiency.
Pressure nozzles or a rotary atomizer spray the feed down towards the fluid bed where agglomeration incorporating finer, recycled material takes place. Exhaust air outlet is let through the roof causing further agglomeration in the spray zone.
Sticky products can be dried successfully, and the concept is ideal for drying heat sensitive products, and improved aroma retention is accomplished.
Product: Agglomerated (instant), free-flowing dustless powders. Agglomerated powders are obtained in systems based upon the integrated fluid bed or belt and a multi-stage concept where moist powder, produced during the first drying stage, forms agglomerates, which are after-dried and cooled in the following stages.
