What is frying and how does an air fryer work on this principle

Frying

In this process of cooking, firstly, liquid fat such as oil is heated to a temperature of 375 degrees Celsius. Secondly, the food, at a normal temperature, is instantly dropped in the hot oil. As a result, due to the sudden transition of temperature on the outer surface of food, the crust dehydrates. Meanwhile, due to the Maillard principle, the chemical reaction between amino acid and reducing sugar gives the food a hard crust, browny color, and moreover a distinctive flavor.

Does an air fryer work on this principle?

The air fryer uses the same principle of frying, however, the medium of transferring the heat now is air in place of oil. A considerable amount of hot air is gushed with high speed and circulated within an air-tight closed chamber where food is placed. This high-speed convection of hot air is termed “Rapid Air Technology” by its inventor company “Phillips”. In conclusion, this technology assists to produce the same effects as deep frying and attain the necessary temperature for the Maillard reaction to occur. Thus, giving a resultant food with hard crust texture, browny color, and above all, the same distinctive taste.

Oil consumption

By now, you must have understood that how an air fryer works without oil. However, this will not get you rid of oil in totality. Even Phillips declares it to be a 94% reduction in fat. This implies that some amount of oil is required, however, the quantity is too little than what is used in deep frying. But it all varies from food to food. Some food like turkey or chicken breast, requires a thin brushing over the surface, whereas, potatoes require few oil drops sprinkled all over. Moreover, food like fish doesn’t require any oil since its body already has plenty of it. You may refer to respective recipes for more information related to oil consumption.

Is an Air Fryer like a Microwave

Principle speaking there is a vast difference between how an Air Fryer and Microwave works.

Air Fryer: As explained above, it heats the food through the convection of high-speed hot air. So the flow of heat in the food is from the outer crust to the inside of the food mass. Thus, the outer surface of the food heats up before the inner mass. The same is explained through the diagram below.

Microwave: The microwave heats up the food by giving oscillations to water molecules present in the food. The oscillating molecules produce the heat and eventually, it escapes from the food. Thus, if we see the heat flow, it is just opposite to that of an Air Fryer. The heat flows from the inner mass to the outer surface of the food. The same is explained through the diagram below. In other words, the microwave does not give you a frying expierence.

An insight into how does an air fryer work and different heat flow in Microwaves will show that you can never get an exact taste of fried or hard crust food through the microwave. So the question – “Is an air fryer like a microwave?” stands false.

Components of an Air Fryer

The components of air fryer can be classified into two broad categories

  1. User Accessible Parts
  2. Internal components

User Accessible Parts

  • Pan: It is sometimes known as an oil collector also. The food basket can be inserted into the pan in most the cases
  • Food basket or a food separator tray: This is where you keep your food for frying
  • Temperature Knob or button: To adjust the desired temperature
  • Timer knob or button: To set the desired time.
  • Preset functions: Digital models have this feature. There are few programmed pre-set modes that can be chosen as per the food. These are basically the combination of temperature and timer programmed as per the type of dish.

Internal Components

Every Air Fryer essentially has these components in common. A general understanding of these internal parts will assist you in knowing how does an air fryer work. To know more about these components read how to fix air fryer at home

  • Fan: Fan helps in the convection of air present inside the food chamber of the Air Fryer.
  • Element: There is a heating element just beneath the fan The element helps in heating the air to the desired temperature.
  • Control PCB: The electronic circuit controls the programming of Air Fryers. Different variants have different sets of circuits. These may be touch panels or digital displays with thermostats and temperature settings.

How to make an Air Fryer work

Since you are pretty sure that how does an air fryer work, now let’s see how to make it work. Air Fryers, in fact, are simple machines to operate.

Following are the 10 easy steps to operate an Air Fryer

  1. Place the air fryer on the Stable, Horizontal, and Levelled surface with a gap of at least 25 inches from the wall on all three sides.
  2. Insert the power plug in the wall outlet and switch “ON” the power.
  3. Press the power ON/OFF button on the appliance to switch it “ON”. This is only available in digital models.
  4. Press the “Manual” button to choose your own settings. You can do it through a control dial or push/ touch buttons.
  5. Set the temperature to 200 degrees Celsius and the timer to 5 minutes. The appliance will start operation once the cooking time is confirmed. This is the pre-heat mode. Some appliances have a separate button for pre-heat.
  6. Post-pre-heat, open the drawer by pulling the handle. Put ingredients as per the capacity in the food basket. Sprinkle oil if required by the dish. Slide the drawer back in its place.
  7. To select the preset menu turn the control dial (or press the desired touch button) to the concerned preset or in the case of analog models to the desired temperature.
  8. Select the timer. Once you select this, the appliance will start operating.
  9. After every 7-8 minutes open the drawer and shake the ingredients within the pan or change the side of food to evenly distribute the heat on all sides to give a uniform effect.
  10. Timer bell will conclude the cooking. Open the drawer and lift the food basket out of the pan. Empty the basket content in a plate. Take out a basket with care since Pan could have oil residues in it which is hot. Air Fryer on the other hand is ready for re-use directly without pre-heat.

Components of differentiation

  1. Type: This is the foremost thing you should decide upon. You may judge the type of air fryers as per your family size or frequency of use. The capacity of the air fryer oven is much more as compared to the compact one and so is the wattage. Additionally, you can select the higher range of temperature in the case of the Oven. This implies that you can cook a larger quantity of food and faster as compared to the Compact type. On the other hand, the oven takes more space and is priced high. However, the principle of how does an air fryer work remains the same for both oven and compact types
  2. Capacity: Next comes capacity. This mostly depends on your family size. For instance, a nuclear family may do with compact type on the other hand for larger families, an oven would be the better choice. The oven comes in a capacity of 20 liters (21 quarts) or more. Whereas in the case of compact types you get more choices. The range varies from 2.2 liters (2.3 quarts) to 5.5 liters ( 5.8 quarts). Ninja Air fryers are designed to provide you with the highest capacity. In fact, they have a very innovative product line like a double-basket food tray.
  3. Looks: This is totally a consumer piece of preference. After all, Air Fryer is a thing of beauty that provides aesthetic pleasure in your kitchen. However, this feature is not related to how does an air fryer work principally. You may go for either an analog or a digital model. Likewise, you may pick LED or LCD displays or at the most with no displays at all. Additionally, you may also choose from different colors and designs as per your preference.
  4. Ease of use and control: You may go in for analog or digital models at your convenience. Air Fryers also comes with some preset menus where the temperature and timing settings are already programmed as per the dish requirements. This will help you out to cook your favorite dishes without manually bothering for settings. Besides, air fryers have also entered the world of IoT. Many brands around the world are working in this field and coming up with newer versions with apps or voice control through Amazon Alexa or Google assistant. This will surely ease the control of Air Fryers.

Meanwhile, manufacturers are working hard to convert the air fryers to a multi-functional appliance in order to provide more differentiation. For instance, new varieties of air fryer machines are coming with the in-built dehydrator function. Refer to Dehydrated Food Benefits and how to prepare one, for more details on the subject.

Further, the wattage, temperature settings, timer range, and warranty are more or less the same across all the variants and brands in a particular region. My piece of advice is that since air fryers are electro-mechanical devices you should go in for the established brands in your region with good after-sales service and spares.
