Abstract

A spraying device having a liquid dispersing nozzle mountable in association with a chamber for directing a stream of gas can be used to provide a spray stream enveloped within a shroud of temperature and humidity conditioned air or gas for controlled evaporation of solvent from spray particles or for preventing reaction of particle components with the ambient atmosphere, and/or to prevent particle deposition and build-up on electrodes positioned so as to produce electrostatically charged particles.
