A spray is created by contacting two fluids, the feed, and a compressed gas .The atomization energy is provided by the compressed gas, usually air. The contact can be internal or external to the nozzle. A broader particle size distribution is generated. The average particle size produced for a given spray dryer feed is primarily a function of ...
