Air fryers use hot air circulation to cook food that would otherwise be soaked in oil. The cooking chamber of an Air Fryer radiates heat from heating elements near the food for more efficient cooking. A fan is usually used to circulate hot air around the food. The opening at the top is used to draw in air, while the exhaust at the back controls the temperature by releasing any unwanted hot air. It is also used to offset any increase in internal pressure. Internal temperature may be as high as 230°C (445°F) depending on model. For your safety, do not put oil in the fryer or place flammable items near the fryer. Typically, cooking time in an air fryer is reduced by 20% compared to a conventional oven. This will vary by brand and the amount of food cooked in the air fryer.
