Air fryers have become increasingly popular in recent years as a healthy alternative to traditional deep frying. An air fryer uses hot air and convection to cook food, resulting in a crispy, fried texture without all the extra oil and fat. But what exactly are the pieces that make up an air fryer and allow it to work its magic?
The Outer Housing
The outer housing is the main external component of the air fryer. It is typically made of plastic and houses all of the internal pieces and components. The housing allows for easy carrying and storage of the appliance. It also containsnecessary openings and vents to allow for proper air circulation.
Air fryer housings come in various shapes, sizes, and colors. Smaller models may have a capacity of 2-3 quarts, while larger models can hold up to 8 quarts or more of food. The size and shape of the housing impacts what types and quantities of food can be cooked. Round, oval, square, and rectangular housing shapes are all common.
No matter what the size and shape, the housing plays an important role in protecting the internal components while still allowing for optimal airflow. Proper ventilation is critical for the air frying process to work effectively.
The Frying Basket
The frying basket, sometimes referred to as the cooking basket, fits inside the air fryer housing. It provides a contained space for the food to sit while the hot air circulates around it. Frying baskets are typically made of stainless steel mesh.
The mesh holes allow for maximum airflow and heat transfer. This exposes all sides of the food to heat, resulting in quick, even cooking and crisping. The holes also allow excess oil and fat to drip away from foods while cooking.
Baskets come in various shapes and capacities to match different models of air fryers. Their size and shape impact how much food can be cooked at one time. Most baskets have a non-stick coating to keep food from sticking while cooking. Some models also come with removable trays or inserts for layering foods.
Heating Elements
The heating elements in an air fryer convert electrical energy into heat energy. They rapidly heat up the air inside the appliance to temperatures between 200°F and 400°F — hot enough to quickly cook and crisp foods.
Air fryers use between 800 and 2200 watts of power. More watts = more heat output potential. The heating elements engage once the temperature setting is selected.
Most air fryers have heating coils made of metal tubing with high resistance. As electrical current passes through them they heat up. Some models may use other heating element styles like a ceramic thermal element.
Beyond creating heat, the elements also help fan out the hot air throughout the cooking chamber via convection currents.
Internal Fan
The internal fan is what sets an air fryer apart from a standard convection oven. It is essential to the air frying process.
The high-speed fan circulates the hot air from the heating elements around and over the food. This allows for very quick heat transfer and creates the crispy texture on foods.
The constant high-velocity airflow mimics deep frying results without submerging food in oil. The fan may be referred to as the convection fan because it creates the convection currents.
In many models, the fan and heating element assembly are designed in a wheel formation that optimizes airflow. The fan is powered by an interior motor that engages when the desired temperature is reached.
Thermostat
The interior thermostat monitors and maintains the air temperature inside the cooking chamber. It communicates with the heating elements and fan to engage or disengage them based on the set temperature.
When the air fryer is turned on, the thermostat sends power to the heating elements. Once it senses the temperature reach the desired cooking level, it cycles the elements off. The fan may continue running to maintain airflow.
If the temperature drops below the target, the thermostat will direct the heating elements to engage again. This creates a consistent hot air environment for crisping and cooking.
The thermostat may be adjustable or preset at a fixed temperature depending on the air fryer model. A functional thermostat is critical for precision temperature control.
Timer
Nearly all air fryer models come with an integrated digital timer to help automate the cooking process. Once the basket is filled with food, the timer can be set to the desired minutes needed for that recipe.
The timer controls how long the heating elements stay engaged. This eliminates the need to manually turn the fryer on and off. Models with digital displays show the countdown time remaining.
When the timed cooking cycle is complete, the fryer will automatically power down. The timer eliminates guessing and prevents overcooking. Most air fryers have timers that can be set up to 60 minutes.
Interior Light
Some air fryer models contain an interior light that turns on when the unit is cooking. This allows the progress of foods to be monitored without opening the basket.
Opening the fryer too often can increase cooking time and decrease efficiency. A light allows foods to be visually checked on without disrupting the hot airflow.
An interior light is handy for air frying items that need flipping halfway through. It also aids in determining doneness on foods like french fries where color signifies done-ness.
Ventilation Openings
The housing of an air fryer contains openings and vents that allow for air intake and exhaust. Intake openings are typically located around the frying basket. This allows fresh air to enter and be heated up.
Exhaust vents then allow for the release of hot air and steam. Proper ventilation is key for optimizing airflow and heat distribution.
If vents become blocked, cooking efficiency will be reduced. Most air fryers have an easy to clean mesh filter over the exhaust to catch any food particles or oil droplets.
Accessories
Some air fryers come with additional accessories beyond just the basic basket. These can enhance functionality and allow for more cooking options.
Common accessories include:
- Cooking pans/pots – Allow for air frying items like cakes, quiches, or casseroles.
- Skewers – Allow for air frying kebabs or other skewered items.
- Grilling trays – Fit over the basket to give a grilled texture.
- Rotisseries – Allow for air frying rotisserie style.
- Dividers – Separate foods in the basket, like fries and nuggets.
The right accessories can maximize the utility of an air fryer. They make it possible to cook more types of foods beyond basic frying.
Temperature and Time Dials/Buttons
Air fryers allow the temperature and timer settings to be adjusted via dials or buttons on the control panel. This offers cooking flexibility and precision.
The temperature dial or buttons will allow the internal heat level to be set to anywhere from 200°F to 400°F depending on the model. This wide range accommodates everything from dehydrating to searing.
Time dials or buttons control how many minutes the cooking cycle will run from 1 to 60 minutes on most models. The ability to customize temperature and time prevents over or under-cooking.
Power Cord
The power cord is what plugs the air fryer into an electrical outlet to deliver energy. Air fryers use between 800 to 2200 watts of electricity, so they require a dedicated grounded outlet.
Most power cords are between 2-3 feet long. Make sure to fully insert the plug into the outlet. The cord, plug, and outlet should all be rated for the wattage needs of the appliance.
Never use an extension cord with an air fryer as it can cause fire and electrical issues. Position the fryer safely so the cord does not create a tripping hazard.
Safety Features
Air fryers contain important safety features to prevent hazards while in use:
- Auto shut-off – If the timer runs down or the fryer overheats, it will automatically shut off for safety.
- Cool touch housing – The outer housing remains cool to prevent burns.
- Safety button guard – Prevents accidental button engagement.
- Skid-proof feet – Keeps the unit stable on countertops.
- Built-in circuit breaker – Shuts off power if electrical faults are detected.
Follow all manufacturer instructions and warnings to use your air fryer safely. Never leave it unattended when hot or in use.
