If you are searching for a deep fryer that uses no oil, then you are indirectly searching for an Air Fryer. Air fryers are a new generation of frying equipment that used either no oil or sometimes minimal quantity of oil depending upon the recipe you are following for your cooking. If you are still wondering how this Air Fryer works without oil, then we have got you covered.
Every Air fryer consists of a cooking chamber that has a heating coil just above the chamber. This heating coil produces heat when the air fryer is on. As it is placed directly above the chamber, so all its heat energy reached the food directly. These heat radiations penetrate deep through the food surface. A fan above the heater pulls the air upwards through the cooking chamber, creating a strong vertical airflow around the food. When the air passes through the heater, its temperature starts increasing. Then the air is guided around the walls of the cooking chamber towards the bottom of the cooking chamber with minimum loss of flow and heat energy. The air is guided upwards by starfish-like air guide from the bottom that distributes the heat evenly in the cooking chamber once again and keeps the airflow in the vertical direction.
The food itself helps to distribute the heat all over the contents of the food basket. Only the bottom of the bucket is open to the air so that it has to pass over the food surface where it transfers the heat to the food. Using this technique, the heat reaches all parts of food even if they are piled up. The combination of the radiation from the top and convection from the bottom creates the heat transfer rate, which is much higher than the rate of a convection oven.
Simultaneously heating from both sides eliminated the need to turn the food in the cooking process. This technique mimics the effects and cooking results that are produced by using a deep fryer.
Air Fryer uses circulating hot air to cook any type of food that would otherwise be submerged in oil. Its cooking chamber radiates heat from a heating element close to the cooking chamber. A fan is generally used to circulate the hot air around the food. The use of little to no oil means that it is low in calories and healthier than the traditional frying method.
The Opening at the top is generally used to take air in, and there is an exhaust at the back that controls the temperature by releasing any undesired hot air. It is also used to counter any increase in internal pressure. The temperature inside can go up to 200 Centigrade or 400 Fahrenheit depending upon the model. Due to the nature of hot air, it is essential as safety not to put oil inside the air fryer or have other flammable objects placed near the air fryer.
In general, cooking times in the air fryer (deep fryer that uses no oil) are reduced by 20% in comparison to traditional ovens. This cooking time varies per brand and the quantity of the food cooked in the air fryer.
