  • Patent number: 9277849
    Abstract: In one aspect of the present invention, a combination dishwashing machine and sink that utilizes a first use solution includes a dishwashing machine, a sump, a pump, a sink, a first fluid passageway, and a controller. The sump is in fluid communication with the dishwashing machine and is configured and arranged to contain the first use solution utilized in the dishwashing machine. The pump is in fluid communication with the sump, and the first fluid passageway interconnects the pump and the sink. The controller is operatively connected to the pump and is programmed to signal the pump to direct the first use solution from the sump, through the first fluid passageway, and into the sink. The controller automates the filling of the sink with the first use solution from the sump.

  • Publication number: 20160031735
    Abstract: The present invention relates to methods, apparatuses, and systems for treating water. The methods, apparatuses and systems reduce scaling associated with solubilized water hardness using a sequence of water treatment agents, including a first threshold agent shedding weak cation exchange resin and a second magnesium compound conversion agent water treatment. The system or apparatus and methods according to the invention provide synergistic reduction of hard water scaling and elimination of cementing on the insoluble magnesium compound.

  • Patent number: 9139800
    Abstract: The invention generally relates to concentrated warewashing compositions and methods of using the same. In some aspects, the invention uses concentrated compositions in methods of warewashing where the concentrate is applied directly to the article to be cleaned, rather than dispensed into a sump and applied to the article as a ready-to-use composition. In additional aspects, the methods of using highly concentrated alkaline and/or acid compositions in an alternating pattern of alkaline-acid-alkaline or acid-alkaline-acid, or the like, provide substantially similar or superior cleaning efficacy while reducing the overall consumption of the alkaline and/or acid compositions.

  • Publication number: 20120291818
    Abstract: A method of warewashing for the optimization of cleaning is obtained, excess detergent usage is minimized and further where deposit of film on ware is reduced in an alternating acidic and alkaline cleaning method. According to the invention, the type of acid and alkalinity used, or acid salt formed upon application of the acidic and alkaline washes is important to cleaning performance and phosphate or silicates should be avoided.

  • Publication number: 20120291808
    Abstract: An automated method and apparatus for cleaning articles by direct application of concentrated product to a soiled surface of the article is disclosed. The article type is identified and a product dispensing sequence is activated to control the type of product dispensed onto the articles based on the article type and/or soil type on the article. Product, duration, and other parameters are tailored according to the article type and/or soil type during each sequence of the wash cycle. Product, wash and rinse liquids are applied at specific locations and from specific directions from within the cleaning apparatus based upon the article type and/or soil type on the article.
