What is an Air Fryer? Why do you really need it?

Last Updated: Dec 28, 2022


Air fryer is a new modern appliance that uses hot air to cook food . It is similar to a convection oven, but uses less energy and produces less heat. The reason people prefer air fryers is that deep-fried items are unhealthy. The use of excess oil increases cholesterol levels which in turn increases heart problems. On the other side, an air fryer uses very little oil and cooks’ healthy food. Air fryers have become popular in recent years as an alternative to deep frying, which is considered to be unhealthy.


Brief History

If we talk about the history of air fryers, originally the concept was introduced by William Maxson during the mid-19th century. His idea was to cook food faster and different than traditional methods. He introduced a device and named it “Maxon Whirlwind Oven”, a large multi-layered oven that used a fan to blow hot air into his equipment to cook food. Although his invention was not that popular in that period.

The idea was later improvised by Fred Van Der Weij, a renowned researcher. On the other hand, Philips, the popular electronic company, was already working to develop a fryer that makes the frying process healthier. But Philips was struggling to convert their idea into a consumer product that would ensure simplicity, ease of use, and cost-effectiveness as well. Fred Van Der Weij started working with Philips on this project in 2005 and took him 3 years to develop a prototype which was an egg-shaped fryer. Then, the air fryer was introduced by Philips company in 2010 at Internationale Funkausstellung, a larger consumer electronics fair in Berlin that attracted a large number of consumers. Now Philips owns the patents for Fred Van Der Weij’s air-frying technology. And this invention resulted in enormous great success.

How does an air fryer work?    

Working & Functionality

Air fryer does not fry the food just like we do deep frying in oil. Instead, it blows hot air on food placed in it so that it gets cooked. The basic principle is that it uses hot air to cook food.

In the top section of the air fryer a fan is placed that blows hot air, then there is a perforated basket in which food is placed just like chicken, fries, and when you turn on your air fryer hot air rushes down and around the food and the food starts to get crispy. The hot air creates a convection effect that cooks the food and changes its color to brown. Most air fryers are portable, and their parts consist of a heating element, a fan on top, and a basket that you can pull out to place items to be cooked. Now let’s discuss the functionality of different parts of the air fryer:

  • Cooking Chamber

The cooking chamber is bowl-shaped area where food is cooked. It has small holes in it just like a net which allows hot air to pass in and out. The hot air surrounds the food from all sides, and the food gets fried and does not become soggy.

  • Heater and Fan

In most air fryers heating element and the fan is placed on top . The heating element starts to raise heat and the fan throws air so with raising temperature air gets hot and passes inside out and food starts to cook.

  • Temperature and Timer Control

With air fryers comes a timer and temperature control system by which you can adjust time and temperature accordingly with your own need and convenience. Normally air fryers cook food more quickly than conventional methods of cooking.

  • Exhaust

An exhaust is also placed in air fryers to manage air temperature inside so that the inner parts get cooled down and the air fryer keeps running. It also drives the smell of cooking food away.
