Abstract: The invention is an alkaline cleaning system which includes an alkaline detergent composition having a pH greater than 10.5 when diluted to a 1 wt-% aqueous solution, and an alkali stable continuous polymeric film dispersible or soluble in aqueous liquids covering the detergent composition. The invention also includes methods of using the alkaline cleaning system by applying an aqueous diluent automatically (by machine) or manually through partial or complete dissolution of the film covered solid.

Abstract: A method of manufacturing a solid cast detergent composition comprising the steps of introducing a solid particulate detergent-component into a mold wherein the particulate defines an interstitial void volume; introducing into the mold, in the absence of substantial agitation, an effective interstitial void volume occupying amount of an aqueous solution of a hydratable alkaline chemical; allowing the aqueous solution to percolate the detergent-component particles; and solidifying the aqueous solution. The preferred detergent-component is a condensed phosphate and the preferred alkaline-chemical is sodium hydroxide.

Abstract: A method and system provide an automated cleaning apparatus for cleaning various types of articles, wherein each type of article is detected and washed according to its own pre-determined combination. The cleaning apparatus has a storage device storing an array of pre-determined chemical combinations and cleaning parameters, including specifying cleaning chemicals to be used on the various identified article types. A transponder is provided with identifying information of the article type. A transceiver detects the type of article from the transponder and communicates that identifying information to a processor. Based on the detected identifier, the processor selects from the storage device the proper chemical combination and cleaning parameters for washing the identified type of article. A control device coupled to the processor delivers the chemicals specified by the selected chemical combination. Finally, a cleaning subsystem coupled to the processor cleans the articles using the delivered chemicals and other specified parameters.

Abstract: An apparatus and method for programming a detergent controller to vary the detergent concentration set-point according to the time of day and to achieve detergent concentration levels quickly without incurring overshoot. Thus, the present invention insures that the warewashing machine is operated at optimum efficiency and cost. To vary the set-point according to the time of day, the invention combines the features of a microprocessor, a clock and a controller into one unit. The user enters the time setting and set point into the controller. The microprocessor then compares the real-time clock signal with the user time settings and outputs an appropriate set-point value from the microprocessor to the controller. To achieve detergent concentration levels quickly without incurring overshoot, the controller senses the detergent concentration and dispenses the proper detergent level to the warewashing machine according to a predetermined detergent feed time based on the previous response time and the programmed set-point. Thus, the controller can change the response function if and when conditions change.

Abstract: A system for proportioning and dispensing concentrated liquid products is disclosed. The components of the system's first embodiment are mounted upon a cart (12). A concentrate solution tube (14) is interconnected to a dilution assembly (61) containing an aspirator (26). A water supply assembly (69), containing a valve (75) and backflow preventer (74), is connected to the aspirator assembly (26) when dilution of the concentrated product (13) is desired. A discharge tube (68) carries the diluted product from the aspirator assembly (26) to a container (60). The system's second embodiment has a spray gun assembly (150) containing an aspirator (167), a valve (166), and preferably though not necessarily, a backflow preventer (165). The concentrate pickup tube (114) attaches to the spray gun assembly (150) with a releasable connector (170). The spray gun assembly has a rigid delivery tube (153) for dispensing to large containers (160), and a nozzle tip (180) for attachment to an inlet port (119) of a jug (111). Also disclosed is a method for dispensing and handling solutions.
