- Abstract
- Industrial oil cookers are found in many major food production plants for processing chicken, fish, potato products, doughnuts and other food products. They have large cooking surfaces and contain tens of thousands of liters of hot oil. Large fires could occur in industrial oil cookers by overheated oil to its auto-ignition temperature due to a system malfunction or simple human error. These fires are difficult to extinguish, and present a severe hazard to the food processing plant as the fires spread rapidly over the oil surface and grow to large sizes. To extinguish the fire, it requires flame extinction over the entire surface at once, and at the same time, rapid cooling of the oil to below its auto-ignition temperature to prevent it from re-ignition.
