Airfryers work thanks to their special cooking chamber. Before we look at how a digital air fryer works, it is important to clarify one fundamental concept: frying is not done with oil, but rather with the high temperatures that the oil reaches. In other words, the oil becomes a heat carrier and enables food to be cooked by reaching high temperatures.
No oil is needed because the heat carrier is the air itself. The heated air generated by the heating elements is circulated at a very high speed so that the food is cooked evenly, simulating the behaviour of oil in conventional frying.
With conventional deep-fat fryers, the food has to be immersed completely in the hot oil or turned halfway through cooking. In hot air frying, the food is completely surrounded by the heat carrier and, as a result, the food becomes crispy on the outside and soft on the inside.
The hot air can be heated up to temperatures of around 200 °C. Because of the high heat demand of the cooking chamber - the heat used to cook the food - airfryers are very energy-intensive, with electricity consumption of between 800 and 2,000 watts.
Thanks to this method, the air fryer only requires minimal amounts of fat and oil (e.g. a small teaspoon) for specific dishes. Fried and breaded dishes nevertheless turn out golden brown and delightfully crispy.
In addition, many other methods of preparation can be employed, such as cooking, simmering and steaming vegetables, meat, fish or seafood, with the cooking juices remaining in the deep fryer instead of evaporating. Equipped with a grill, gridiron, griddle and baking functionality, a hot air deep fryer is moreover able to roast, grill, thaw and roast and is, therefore, able to replace your stove, indoor electric grill and oven.
Like any new appliance, a newly purchased air fryer or hot air fryer may emit an unpleasant smell when first used. To remove unpleasant odours , one trick is to place a piece of bread or an apple cut in half in the basket, then set the temperature to 180 °C and let it warm for about ten minutes. This will remove the 'new' and plastic smell from the appliance and you can start preparing your first tasty recipe straight away!
