  • Patent number: 8201570
    Abstract: A cover assembly for sealing a dishwasher drawer includes a rigid, movable cover casing that frames a flexible sealing cover which is capable of receiving and covering tall dishes extending beyond a height of the drawer. Rocker arms are placed on each perimeter edge of the cover casing, and pivot to raise and lower the casing onto the drawer so that the sealing cover seals a wash chamber therein. A seal adhered to a bottom of the cover casing presses against a lip of the drawer to prevent leakage of wash fluid circulated therein.

  • Patent number: 8163098
    Abstract: The disclosure features a method of performing a boil-out cleaning process in connection with a fryer. The fryer includes a vat, a vessel for receiving oil drained from the vat, the vessel movable from an under-unit position, an oil drain path leading from an outlet opening of the vat to the pan, and an oil return path from the vessel back to the vat. The oil return path includes a pump. A drain valve is located along the oil drain path. The drain valve is opened to drain oil from the vat into the vessel is opened. The drain valve is closed after draining the oil from the vat. A boil-out cleaning fluid is delivered to the vat and the boil-out cleaning fluid is heated. A boil-out drain path is provided with an inlet positioned for receiving boil-out fluid from the drain valve and an outlet positioned forward of a front of the fryer unit. A container is placed below the outlet of the boil-out drain path.

  • Patent number: 8122898
    Abstract: A rotating and telescoping cleaning system improves high pressure water cleaning of the inner surfaces of vessels or tanks. Vessels can be vertically divided with dividing plates with centered through-holes. Synchronized and controlled transverse and rotary movements of water jets result in a controlled spiral or helical cleaning track along the vessel walls. The water jets are directed at a pre-adjusted distance from the vessel wall and the travel speed of the water nozzle jets is exactly controlled allowing the removal of very hard deposits. One pass with the tool carrier with operating water jets along the length axis of the vessel results in a thoroughly cleaned vessel wall. The tool unfolds and folds inside of the vessel powered by the flow of the high pressure cleaning water.
