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.

I claim: 1. 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. 2. The system of claim 1 wherein said area is a rectangular area of about 4 feet by 5 feet. 3. The system of claim 2 wherein said areas covered by mist spray subtend substantially all the oil in the pan. 4. The system of claim 1 including a water delivery pipe gridwork above the cooking oil in the pan, and supporting the nozzles. 5. The system of claim 2 including said hood supporting a water delivery gridwork. 6. The system of claim 5 in which the hood is supported 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. 7. The system of claim 1 wherein the water pressure supplied to the nozzles is between 50 and 1500 psi. 8. The system of claim 1 wherein there are an edible or edibles in the pan in contact with the oil in the pan, the oil top level being selected in relation to controlled elevation positions of the nozzles, to enable mist coverage of all oil in the pan, and an edibles conveyor traveling longitudinally in the pan, below nozzle rows. 9. The system of claim 1 wherein the selected positions of the nozzles above the oil top level are controlled so that mist produced by the nozzles will travel laterally to pan edges, directly above the oil in the pan, and along the pan length. 10. The system of claim 1 wherein the nozzles are selectively directed relative to vertical, and azimuthly to assure mist coverage of hotter zones in the oil. 11. 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. 12. The method of claim 11 including cooking an edible or edibles in the pan in contact with the oil in the pan, the oil top level being selected in relation to controlled elevation positions of the nozzles. 13. The method of claim 11 wherein the elevation positions of the nozzles above the oil top level is controlled so that mist produced by the nozzles will travel laterally to and over pan edges, and directly above the oil in the pan, and along the pan length. 14. The system of claim 1 wherein said control means includes at least one flame or heat detector, and circuitry and valving to initiate water flow to the nozzle or nozzles as in one or more rows, to provide mist production at all nozzles for abundant coverage of all the pan oil, in response to flame detection. 15. The system of claim 14 wherein the nozzles extend in two rows extending longitudinally and being laterally spaced, the nozzles longitudinally spaced apart in each row. 16. The system of claim 14 wherein there is only one row of nozzles, which are longitudinally spaced apart.
