Abstract: A solvent control arrangement for stripping liquid solvent from parts being degreased/defluxed in a degreaser or defluxer by intimate contact with liquid solvent or a vapor phase thereof is disclosed. The solvent control arrangement comprises a tank or box having an open end extending downwardly into the vapor zone in an exit area of the degreaser/defluxer to define a flash drying chamber above and in communication with the vapor zone. The solvent covered parts are directed into the flash drying chamber from the vapor zone where heat is applied to heat the air in the flash drying chamber to a temperature above the solvent boiling point to thereby evaporate liquid solvent on the parts. The parts are then returned from the chamber into the vapor zone where they ultimately exit the degreaser/defluxer from the exit end. Optionally, condensing coils may be disposed in the chamber at the vapor line to condense solvent in the chamber and prevent the solvent vapor zone from encroaching within the chamber.

Abstract: An apparatus for vaporizing a liquid and condensing the vapor includes at least one chamber in which the liquid is vaporized and in which the vaporized liquid is condensed. The vaporizing chamber contains a heat emitting device providing a surface temperature above the vapor temperature for substantially instantaneously vaporizing the liquid condensate maintaining a predetermined vapor level in the vaporizing chamber, and a heat absorbing device for condensing the vaporized liquid.

Abstract: An apparatus for generating at least two vapor zones, one above the other, by vaporizing a fluid mixture having at least two compounds therein having different vaporizing temperatures. The apparatus includes a chamber with vaporizing means, and vapor condensing means. Condensate recovery means is provided for recovering the condensed vapor and the condensate recovery means is in flow communication with a separation device for receiving the condensate from the condensate recovery means. The flow communication between the condensate recovery means and the separation device is external of the chamber. The separation means revaporizes the liquid with the lower vaporizing temperature for return to the vapor zone in the upper portion of the chamber and separates as a liquid the fluid having a higher vaporizing temperature.
