The difference between air fryers and traditional oil fryers and ovens.

Traditional oil frying involves wrapping the ingredients in edible oil, which can quickly and evenly transmit heat energy. The surface temperature of the ingredients increases rapidly, and the water evaporates, making the surface crispy; Air fryers use hot air to wrap the ingredients and produce similar effects. The biggest difference between the two is that air fryers can use no or less oil, with almost no oil fumes. Cooking is done in a closed pot, and hot oil will not splash and burn people everywhere.
Oven baking uses the heat radiation emitted by electric heating elements to cook ingredients, while air fryers use hot air circulation to cook ingredients. Generally speaking, air fryers can be seen as a simple small oven with a hot hair dryer. The biggest difference between the two is that when making a small amount of baked ingredients, the air fryer is faster and easier, while when baking a large amount of ingredients or when baking ingredients, the oven is more suitable.
However, it is worth noting that the statement promoted on the market that "air fryers are healthy when cooked without oil and will not cause weight gain or overheating" is actually inaccurate and misleading. Air fryers can indeed reduce our intake of oil, but they are not completely oil-free. On the one hand, some ingredients come with oil, and no matter how "fried" the food is, the harm to human health after consumption is the same, and it is not recommended to consume too much, On the other hand, some product recipes suggest that some ingredients be coated with a layer of oil before making, so air fryers are at best only harmful products, not products that can purely bring health.
