Information on our Fluidized Spray Dryer- FSD™ which gives an advantage to powder producers.
Fluidized Spray Dryer - FSD™- Combines spray drying and fluid bed drying technologies.
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 post-dried and cooled in the following stages.
FLUIDIZED SPRAY DRYER (FOOD AND CHEMICAL) / MULTI-STAGE DRYER (DAIRY)
The FSD™ and the MSD™ combine spray drying and fluid bed drying technologies and offers excellent product flexibility and thermal efficiency.
Fluidized Spray Dryer: 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 through the roof causing further agglomeration in the zone of spraying.
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.

MODE OF OPERATION
Spray Dryer: The feed is sprayed from the atomization nozzle mounted on top of the drying chamber into the drying air and down the spray chamber. The vigorous fluidization of moist powder in the fluid bed located at the chamber base, plus recycle of fines from the cyclone attachment, result in spray drying taking place in a powder-laden atmosphere.
Particles of higher moisture content can be handled in the drying chamber due to the resulting powdering effect overcoming the problems of powder stickiness. Drying can be completed at lower powder and exhaust air temperatures, thus improving product quality while gaining from a higher thermal efficiency. The degree of agglomeration and thus the particle size distribution can be influenced by changing the operation conditions.
