Question

Physics behind airfryer: How does an air fryer work? Does it really use air to fry food without oil?

Answer 1

Air fryers use a circulation of hot air to cook food that would otherwise be submerged in oil. The air fryer's cooking chamber radiates heat from a heating element near the food, thus cooking it more efficiently. A fan is generally used to circulate hot air around the food. The opening at the top is 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 increases in internal pressure. The temperatures inside can go up to 230 °C (445 °F) depending on the model. For safety, it is essential to not put oil inside the air fryer or have flammable objects near the air fryer. In general, cooking times in the air fryer are reduced by 20% in comparison with traditional ovens
