How Do Air Fryers Work? Top 10 Air Fryer Benefits

Air fryer is a relatively new and revolutionary cooking appliance that is primarily used to ‘deep fry’ menus. It is manufactured and patented by Phillips Electronics and was officially introduced in the market in the year 2010. It operates on the principle of rapid air technology and is also used to grill, roast, bake, and steam foods. In the discussions that follow, the various aspects of the appliance are going to be discussed in details. In this article, we will search the answer to how do air fryers work.

How Do Air Fryers Work?

They basically comprise a heater element, exhaust system, a filter, a removable tray, a large fan, a cover, and a star-fish-like air guide at the bottom. They prepare food using the ‘Rapid Air Technology’ that is explained below:

The food to be prepared is placed in the removable tray. The heater element that is located right above the food generates heat in the form of radiation. The radiated heat penetrates deep under the food surface. A large fan above the heater pulls the air upwards through the cooking chamber and generates a strong air flow while passing the heater. This air that is loaded with heat energy is transported downwards.

The star-fish-like air guide directs the heated air in a vertical direction and also distributes the heat evenly. This enables the heat to reach all parts of the food even if it is piled up. The combination of radiation from the heating element above the food and the convection from below the food negates the need to constantly turn the food up and down in times of cooking.

The internal re-circulation of cooking air increases the pressure of the air inside the fryer. This may cause the appliance to explode if not released in time. That’s where the exhaust system comes in. The exhaust system releases a small amount of air into the atmosphere to reduce the air pressure inside the fryer. The filter ‘traps’ odor from the food and only releases ‘fresh air’ into the atmosphere. This keeps the kitchen interior as clean and breathable as possible.
