Abstract
A cooker system, comprising a relatively wide pan containing cooking oil at high temperatures, the pan extending longitudinally, for cooking edibles located longitudinally, single or multiple row water mist producing nozzles supported above the pan, there being one or more laterally spaced nozzles at longitudinally spaced locations above the pan, each nozzle producing mist substantially covering an area of at least about one square foot, at oil surface level in the pan, and control means to control pressurized water delivery to the nozzles, in the event of fire in or associated with oil in the pan.
Claims16
Cooker system, comprising:
- a) a relatively wide pan containing cooking oil at high temperatures, the pan extending longitudinally, for cooking edibles located longitudinally,
- b) single or multiple row water mist producing nozzles supported above the pan, there being one or more laterally spaced nozzles at longitudinally spaced locations above the pan,
- c) each nozzle producing mist substantially covering an area of at least about one square foot, at oil surface level in the pan,
- d) and control means to control pressurized water delivery to the nozzles, in the event of fire in or associated with oil in the pan,
- e) there being a vertically movable hood above the pan, the hood having a top wall extending over oil in the pan, the nozzles carried at said top wall, and a water supply line above said top wall and extending to the nozzles.
The method of suppressing flame production in or associated with hot cooking oil in a relatively large size, longitudinally extending pan, that includes the steps
- a) providing a relatively wide pan containing cooking oil at high temperatures, the pan extending longitudinally,
- b) producing water mist at nozzles supported above oil level in said pan, the nozzles spaced apart laterally so that mist from each nozzle covers only part of the lateral extent of oil in the pan, at selected oil level,
- c) each nozzle producing mist substantially covering an area of at least about one square foot, at oil surface level in the pan,
- d) providing and operating control means to control pressurized water delivery to the nozzles, in the event of fire in or associated with oil in the pan,
- e) providing water delivery pipe gridwork above the cooking oil in the pan, and supporting the nozzles,
- f) providing a hood over the pan, and supporting the gridwork,
- g) and supporting the hood for movement, vertically, to elevate and lower the gridwork and nozzles, to assure mist coverage of all oil in the pan, the oil level being selectable.
