The Fluidized Spray Dryer produces 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.
FLUIDIZED SPRAY DRYER (FOOD AND CHEMICAL) / MULTI-STAGE DRYER (DAIRY)
The combination of spray drying and fluid bed drying technologies within the FSDTM and the MSDTM offers excellent product flexibility and excellent thermal efficiency.
The feed is sprayed down towards the fluid bed by either pressure nozzles or a rotary atomizer. The agglomeration, which incorporates finer and recycled material takes place in the fluid bed. Exhaust air outlet is 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.
