Nowadays, more and more people advocate air frying. So what is air frying and what are its similarities and differences compared to deep frying? First, let's study the definition of the word "deep frying": deep frying is a cooking method, and the earliest definition of deep frying was to put the ingredients into a hot pot with high oil and use high or warm heat to cook them. The reason for choosing oil is because its boiling point is relatively high, usually above 200 ℃, which is twice as high as the boiling point of water at 100 ℃. This high-temperature heating of ingredients can quickly heat and cook the food in a short time, thereby locking in the freshness of the ingredients themselves. Therefore, fried food will be more delicious than cooked food.

Air frying and deep frying have similarities and differences. Air frying uses a heat source to heat the air to a very high temperature, and then uses high-temperature air to wrap the ingredients, allowing them to quickly cook at high temperatures while achieving the effect of freshness retention. Because air is a conductor of heat and has no boiling point, as long as the temperature of the heat source can be raised, the temperature of the air can continue to rise. The difference in taste between air fried ingredients and deep fried ones is not significant.

So what is the difference between air fried and deep fried food? Because deep frying involves wrapping ingredients in high-temperature oil, it is difficult to lose moisture and oil from the ingredients. The fried ingredients are tender and also very greasy, especially in modern times where most people's diets are high in oil, salt, and sugar. Excessive intake of oil and fat can be harmful to health, so it is best to eat less deep fried food. Air frying, on the other hand, involves the entry of high-temperature air into ingredients. During the heating process, it forces out a portion of the food's moisture and most of its fat, which can help to remove oil and fat. The fried ingredients are crisper and have a lower fat content, making them more suitable for modern consumption.

Overall, the cooking principles of deep frying and air frying are essentially the same, but the food produced by deep frying is more crispy, has a high fat content, and is very unhealthy; Air fried food is more crispy and can reduce fat with light oil, making it more suitable for consumption.
The basic structure of an air fryer
Air fryer is a device that realizes air frying, and its structure is relatively simple. The current air fryer is basically a high-speed fan with a spiral heating tube attached to it, surrounded by a temperature sensor, and then paired with a fryer (frying basket) filled with ingredients. When the machine is running, the fan rotates at high speed, continuously blowing high-temperature air near the heating tube towards the fryer, causing the air inside the fryer to circulate quickly, ultimately achieving the effect of high-temperature air wrapping the ingredients.
Selection parameters for air fryers
Important parameter one: Power
Although the structure of the air fryer is simple and the price is relatively cheap, there are also considerations when choosing it. Firstly, for a heating device, its most obvious parameter is its power. As mentioned earlier, air has no boiling point, so as long as the power is high, the temperature of the air will be higher, and the ingredients will be heated faster. Is it better to have a higher power? Of course, this also depends on the heating needs of the ingredients, so the best choice is to have a higher heating power. However, the power is widely adjustable, which is reflected in the wide range of temperature adjustment, such as the temperature can be adjusted from 80 ℃ to 200 ℃.

Important parameter 2: Temperature control
The second important parameter of the heating device is temperature control, which is the sensitivity of the temperature sensor. Whether it's an air fryer or an oven, it's difficult to achieve precise temperature control and even temperature inside the chamber. However, the more accurate the temperature control, the more evenly the ingredients are heated, and the higher the success rate of the novice operation. For air fryers, the main way to improve temperature control accuracy is to increase the number and quality of temperature sensors, increase the fan speed, increase the number of fan blades, and increase the fan blade area.

Important parameter three: Noise
In addition to power and temperature control, another unique parameter of an air fryer is noise. Because air fryers mainly rely on high-speed rotating fans with internal hot air circulation, it is inevitable that there will be noise. The main way to reduce noise is to choose high-quality motors, so when choosing, attention should also be paid to the motor aspect.
Other parameters
In addition to these hard parameters, the design of air fryers is also very important. It is easy to notice the volume, operation method, intelligence, and ease of cleaning of the air fryer. At present, the air fryers on the market are mainly drawer style, and the inner tank of the fryer is often equipped with a hollow oil filter basket. When cooking, the ingredients are at a certain distance from the bottom of the pot, and high-temperature air can wrap the ingredients 360 degrees in all directions. The materials for the fryer and oil filter basket are both non stick inner pot materials, which are easy to clean and much easier than traditional air fryers with windmill bottoms.

Purchase Summary
In short, air fryer selection, with high power and wide adjustable range, accurate temperature control, low noise, large capacity, easy operation, and easy cleaning, is definitely an excellent air fryer if all these conditions are met.
