Fried. Without an air fryer, you can fry semi-finished chicken nuggets with iron pan and oil at high temperature. Air fryer is a machine that can use air to "fry", mainly using air to replace the hot oil in the original frying pan to make food mature; At the same time, the hot air also blew away the moisture on the surface of the food, which made the ingredients achieve the effect of approximate frying. The working principle of the air fryer is "high-speed air circulation technology". Hot air is generated by the heat pipe in the high-temperature heater, and then the high-temperature air is blown into the pan by a fan to heat the food, so that the hot air circulates in the closed space, and the food is fried by using the grease of the food itself, so that the food is dehydrated and the surface becomes golden and crisp, thus achieving the frying effect. So the air fryer is actually a simple oven with a fan.
