Spray Drying - 3" SpiralAir 3101

By BETE Fog Nozzle, Inc.

Customers often purchase BETE SpiralAir nozzles for air-atomized spray drying. The use of air-atomized SpiralAir nozzles allow high product flow rates while still maintaining a relatively small particle size, usually less than a 100 micron Sauter Mean Diameter (D32). The replaceable Cobalt Alloy 6 wear components available for this nozzle allow it to have comparable wear life to traditional spray dry nozzles. This particular customer had been using SpiralAir nozzles for spray drying for some time, and was happy with the results. However, they were building a new, much larger drier, and wanted to use a single nozzle to spray 5 - 40 GPM (20 - 150 l/min) of product.
