The Principle Behind Air Fryers

Air fryers of different brands call their technologies by different names, but their functioning is all based on the same principle. 

When you turn on your air fryer, it does basically this:

  • One or more heating elements heat the air and bring it to a very high temperature
  • A fan blows the hot air into the cooking chamber
  • The hot air keeps circulating thanks to the activity of the fan, usually at high speed.

With this simple system, you can obtain these results:

  • The food is evenly cooked because every surface comes into contact with the same amount of hot air
  • You don’t need to change the position of your food during the cooking
  • You obtain a crispy outer layer on your food as though it was fried. This is why such devices are called air fryers. 1
