Air fryers have become an incredibly popular kitchen appliance in recent years. They provide a healthy way to fry and roast foods by using super heated air rather than oil. Air fryers have a number of different parts that work together to cook food quickly and evenly. In this article, we will take a look at the main components of an air fryer and what their functions are.
The Outer Body
The outer body or housing encloses all of the air fryer’s inner workings and components. It is typically made of plastic with a plastic or metallic coating. The housing serves several important functions:
- Protects the internal components
- Insulates the super heated air
- Contains grease and oil splatter
- Provides an aesthetic look
The body will have buttons or dials to control cooking settings as well as a handle and/or button to open the cooking chamber. There are vents on the top, back, and sometimes sides that allow airflow. The body also contains all of the electronic components that power and control the air fryer.
Cooking Chamber
The cooking chamber, also called the basket or pot, is the inside compartment where food is placed for cooking. It is removable for easy loading and unloading of food. The cooking chamber is made of metal with a non-stick coating such as ceramic or Teflon. This prevents food from sticking and allows for easy cleanup. The basket may have a mesh or grated bottom to optimize airflow.
Some air fryer models come with different sized pots or racks to accommodate cooking larger or smaller amounts of food. The pot slides into place and gets securely locked for safe cooking. During cooking, hot air swirls around the cooking chamber providing the rapid airflow needed to crisp and brown foods.
Heating Element
The heating element generates the hot air used to cook the food in the air fryer. It is a coil similar to what you would find in a conventional toaster or oven. The coil is generally made of metal or ceramic and heats up when electrical current passes through it. As it rapidly heats to temperatures around 400 degrees Fahrenheit, the surrounding air becomes superheated.
This superheated air then gets circulated throughout the cooking chamber by an internal fan. The high temperature allows the air fryer to cook food rapidly and impart browning and crisping. The heating element has sensors that communicate with the internal computer to regulate temperature.
Internal Fan
The internal fan is a critical component as it’s responsible for moving the hot air around the food. It is powered by a small motor and spins rapidly during cooking. The constantly circulating high velocity air is what gives air fried foods that crispy texture.
Without the fan, the hot air would not flow properly within the chamber. The fan pushes the air over and around the heating element, taking heat from it. The fan then channels the hot air throughout the cooking basket using specially designed air ducts and vents.
Control Panel
The control panel allows you to operate and program the air fryer. It generally consists of several buttons and a display screen. Some common functions found on an air fryer control panel include:
- Power button to turn device on/off
- Temperature control to set heat from 250F to 400F
- Timer to program cooking time up to 30 minutes
- Digital display showing temp, time settings
- Preset buttons for commonly cooked foods
- Start/Pause button to begin cooking
More advanced models may have preset cooking programs that automatically set the temperature and time for certain foods with just a button press. The control panel communicates with the internal computer chip and other components to operate the appliance.
Internal Computer
The internal computer processor allows the air fryer to operate electronically. It is located within the main housing. The computer chip gets input from the control panel and temperature sensors. Based on programming, it automatically adjusts appliance operations including:
- Turning heating element on/off
- Starting/stopping fan
- Displaying digital settings
- Running preset cooking programs
- Shutting off when timer expires
This automation provides ease of use and takes the guesswork out of air frying. The computer also includes safety functions that prevent overheating or fire hazards.
Temperature Sensors
Most air fryers have sensors that monitor the temperature inside the cooking chamber. There is typically one sensor near the heating element and another near the food. These sensors communicate with the computer to regulate temperature for proper cooking.
Here’s how they work:
- Sensor detects air temperature within chamber
- Sensor sends signal to computer
- Computer compares sensor reading against set temperature
- Computer adjusts heating element output to achieve target temp
If the air is not hot enough, the computer will increase the heating element’s power. If it’s too hot, the computer will turn the element down or off. This feedback loop allows precise temperature control for perfect cooking results every time.
Safety Features
Modern air fryers come equipped with a range of safety features to prevent accidents while cooking. These can include:
- Auto Shut-Off – If the timer expires, the fryer will automatically turn off. This prevents overcooking or fires.
- Overheat Protection – If the appliance overheats, the computer will cut power to the heating element.
- Cool Touch Exterior – The body remains cool making it safe to touch.
- Safety Lock – The cooking chamber locks securely in place for safe operation.
- Breakaway Power Cord – If accidentally pulled, the cord detaches to avoid tipping the appliance.
Always check that any safety features are functioning properly before use. Only operate the air fryer on a stable, heat-resistant surface away from flammable items.
Accessories
Air fryers come with a range of accessories and extra parts. These can enhance functions and allow you to cook different types of dishes. Common air fryer accessories include:
- Extra cooking pots/pans – Additional pans designed to fit in the fryer and hold different amounts of food.
- Cooking tongs – Allows safe handling of hot food.
- Rotisserie spit – Skewers food and rotates for even cooking.
- Grill pans – Impart grill marks while air frying.
- Bake pans – Pans for cakes, muffins, and other baked goods.
- Cooking racks – Include layers for increased capacity.
- Skewers – Hold meat, vegetables, and other foods.
- Food trays – Shallow trays keep breaded foods crisp.
Accessories add flexibility to what you can cook and how much. They allow you to get even more utility out of your air fryer.
Types of Air Fryers
While all air fryers operate on the same basic principles, there are a few different designs:
Basket Air Fryers
This is the most common type and consists of a central basket that slides into the heating chamber. Food cooks in the suspended basket while air circulates all around it. The basket has an open design that promotes air flow.
Dual Basket Air Fryers
These have an upper and lower cooking basket. The dual baskets allow you to cook two different foods at once without mixing flavors. While one basket air fries, the other basket can bake or broil.
Flat Bottom Air Fryers
Rather than a basket, these have a solid flat bottom plate or pan that sits inside the chamber. The flat pan is better suited to cooking things like fries, eggs, pancakes, or crepes.
Flip Style Air Fryers
This type has a hinged chamber that flips over during cooking. The food starts at the bottom and gets flipped upside down midway through. This allows for even browning without the need to shake or stir the food.
Round Air Fryers
Instead of the more common square/rectangular shape, these air fryers use a rounded cooking pot. The shape helps with air circulation and heat distribution.
Toaster Oven Air Fryers
These combine an air fryer with a convection toaster oven. They have settings for baking, broiling, and air frying, making them versatile. They are also larger to accommodate whole chickens or pork loins.
