Similarly, an exhaust fan is also present which generates rapid hot air which moves inside the chamber of the fryer. Without the loss of much energy, your food gets cooked from all sides.

For example, you can cook crispy chips in around 15 minutes in an air fryer whereas the traditional ovens need at least half an hour for making chips crispier. The heat inside the appliance does not dry your food at all. The heat that originates from the topmost and the bottom-most section makes your food cook rapidly at the right temperature.

The next important part is the exhaust system which plays a significant role in the working of the air fryer. As soon as your food is cooked, you can recognize that with the help of the smell of the food. The exhaust system of the air fryer filters out the extra air before making it release. It is the reason that you will never smell any odors inside the kitchen or your room.

As soon as there is enough hot air inside the air fryer, the exhaust system starts working instantly. It finishes the steam and smoke inside the fryer before releasing into the outside air.

3. Cooling System

A cooling fan over the motor of the air fryer given for controlling the inner temperature. The filters of the fryer allow the air to pass through them so that the internal parts of the appliance can remain cool. It results in the proper overall cooling of the machine. As a result, the hot food can be served just after the process of stir-frying is finished.​

The temperature control of the appliance switches off the heater coil when the desired cooking temperature reached.

Hence, we can say that during the entire process of air frying, only for 2/3rd of the time the power of the heater used and for the 1/3rd period, the heating coil's energy consumption is 'OFF.'

The cooking time of 30 minutes in an air fryer is only gotten on rare occasions when your food is hard to cook. Typically, it takes around fifteen minutes to cook food in the fryer. Therefore, the maximum amount of electricity which is used by an air fryer is not more than ½ a unit of power in a single day.
