This invention relates to mixing two substantially immiscible fluids having substantial viscosity differences into a single phase solution. The invention particular includes a mixer comprising a specially designed conveyor flights to provide shear mixing without differential conveying of the fluids or causing excessive back pressure or pressure drop on the solution.

Forming a solution of fluids having low miscibility and large-scale differences in viscosity

A device for spraying and baking panels within a single automated unit. The spray booth and baking environment are differentially pressurized and purged such that the unit can be located with an environment which is electrically classified as hazardous for flammable materials. Parameters unique for processing materials to be used are programmed into a control computer. Mounted within the spray chamber is an emissions reduction attachment which collects paint and wash liquids used in purging the spray gun during the spray cycles. Significant increase in the useful life of materials collecting paint overspray and a decrease in airborne emissions can thereby be achieved.
