ABSTRACT:
A system for converting powdered detergent in a shipping container into a concentrated detergent solution and for maintaining a predetermined volume of the solution available for use by a remotely located washing apparatus. A chassis defines a reservoir suitable for holding concentrated detergent solution and has an inlet port opening into the reservoir. A curved screen member is continuously mounted across and extends into the open mouth end of a detergent-filled container. A cradle assembly pivotally positions the container and screen in inverted position over the inlet port to the reservoir such that the curved screen retainably supports the detergent within the container. A single nozzle is mounted at the inlet port for uniformly directing a spray of solution from the reservoir against substantially the entire downwardly facing surface of the screen, dissolving a portion of the detergent carried thereby, which passes in solution through the screen and into the underlying reservoir. Automatic safety control apparatus protects operators of the system from hazardous spray of solution from the nozzle by preventing energization of the pump which feeds solution to the nozzle whenever the container is not operatively positioned overlying the inlet port and in locked sealing engagement with the chassis.
