Abstract

A spray drying system having a whirl chamber nozzle with a bypass and for atomization of a liquid. The whirl chamber of the nozzle has a central discharge orifice, from which a ring-shaped bypass passage extends radially outwards. This ensures that substantially no air enters the bypass from the whirl chamber, while providing acceptably low flow growth values.
