Principle of air fryer

The hot oil in the original frying pan is replaced by air, which is heated by convection similar to the sun's hot air. The hot air forms a rapid circulating heat flow in the closed pan, which makes the food cooked, and at the same time, the hot air also blows away the moisture on the surface of the food, so that the ingredients can be fried approximately without boiling oil. The principle of air fryer is that it has a door like a drawer, and uses high-temperature hot air to circulate in a closed space to fry food.

The air is quickly heated by the baking device at the top of the machine, and a fast circulating heat flow is formed in the frying pan by a high-power fan. The special lines in the frying pan form eddy heat flow, which contacts the surface of the food in 360 degrees and quickly takes away the water vapor generated by heating, thus forming a golden crispy surface layer on the surface, achieving the appearance and taste of frying. At present, the most advanced high-speed air circulation technology in the world only uses air for cooking, and no oil or less oil is used.
