  • Patent number: 8029271
    Abstract: A self-cleaning burner system incorporates an automatic clean cycle when the burner is started up. Cycles may be programmed for once-a-day cleaning cycle or for other desired interval. On start-up, the cycle routes a small amount of fuel to the burner for ignition inside the burner to clean the burner surfaces. The system incorporates an igniter for fast, routine, and safe ignition of the fuel. Thus, small amounts of debris that accumulate on a surface burner are automatically ignited when the burner is started, keeping the burner clean and operating at a high state of efficiency at all times. The self-cleaning burner system may be incorporated into a fryer or other heating appliance for reliable, efficient operation.

  • Patent number: 7311038
    Abstract: Improved features for a filter system for a deep fat fryer are described. The fryer includes a movable filter pan disposed below the cooking tank which is fed by gravity when the tank is drained through a downspout. The downspout is curved and rotatable from a down position when it is in use/storage to an up position when it is not in use and a stabilizing clip is mounted on the downspout to secure a separate polishing tube when it is in the down or horizontal position to allow one handle to lift two pipes at the same time for removal of the filter pan. An inline removable filter is provided in the oil return line, and the return line is slidably supported on the side of the filter pan so that it can rise and fall with the debris in the filter pan.

  • Patent number: 6378420
    Abstract: A filter system for a deep fat fryer is described. The filter system can be used in a single fryer or with two or more sequentially operated fryers. In the later case, a common filter pan is used with a horizontal filter in the pan, disposed below a common drain pipe. A return pipe is mounted in the center of the filter. This pipe is connected to a pump inlet so that oil to be filtered is admitted to the pan above the filter, and filtered oil is removed from the pan through the filter. Filtered oil is then circulated by the pump through a three port valve to return the oil to the appropriate fryer tank. If the valve is closed the oil will be routed through the valve to an adjacent tank valve for admission to that tank so that a single pump may be used for a plurality of tanks. An optional flush system can also be provided so that oil can be used to flush a tank manually.
