Abstract
The preferred embodiment of the shielded counter-rotating spinner assembly for microparticalization of liquid consists of two opposed, coaxial, counter-rotating, conical, sharp-edged spinners whose edges are in close proximity and whose outer surfaces are in close proximity with non-rotating shields which extend to the edges of the spinners. The purpose of the shields is to greatly reduce the spinner induced air drafts so that, when liquids are applied to the inside surfaces of the spinners through the axes of the driving motors, the droplets produced on the edges of the spinners are injected into very low velocity air. The benefits of accomplishing this are the realization of very short droplet trajectories, the concomitant reduction in size of a plenum chamber which might encompass the device, the production of dense fogs of liquid droplets, and the ability to efficiently mix a liquid with a gas or to mix binary liquid chemicals together away from the device, but within a restricted volume where the atmosphere may be controlled and the production of solid droplets from the liquid phase through cooling in a finite volume and within a controlled atmosphere.
