Title:
METHOD AND APPARATUS FOR EVAPORATING MULTI-COMPONENT LIQUIDS
Document Type and Number:
WIPO Patent Application WO2003066115
Kind Code:
A3
Abstract:
An atomizer 10 atomizes a multi-component liquid from a reservoir 20 into a cloud 14 comprising small droplets 38 which are ejected into the atmosphere to a certain height and allowed to fall toward a surface 12. Essentially complete evaporation is assured by maintaining the size of the droplets, the liquid's component vapor pressures and the height through which the droplets fall according to a predetermined relationship. Also, the suitability of a liquid for evaporation in a vibrating plate atomizer is determined by measuring the rate of size decrease and the surface tension of a pendant drop of the liquid after a predetermined amount of the liquid has evaporated from the drop.
