How does Household Air Fryer precisely control the hot air circulation during cooking?

Household Air Fryer is popular among consumers for its healthy and convenient cooking method, and precisely controlling the hot air circulation during cooking is the key to achieving delicious cooking results.
One of the core components of an air fryer is the heating element and the fan. The heating element generates heat, and the fan is responsible for circulating the hot air evenly inside the fryer. In terms of precisely controlling the hot air circulation, advanced temperature sensors are first relied on. These sensors can monitor the temperature inside the fryer in real time and feed the data back to the control system. For example, when the cooking temperature is set to 200℃, the temperature sensor will continuously detect temperature changes. Once the temperature is lower than the set value, the control system will instruct the heating element to increase the power and adjust the fan speed at the same time to make the hot air circulate quickly and quickly increase the temperature; when the temperature approaches or reaches 200℃, the heating element power is reduced and the fan maintains an appropriate speed to maintain a stable temperature environment.
Different ingredients require different hot air circulation modes. Some air fryers have multiple preset cooking modes, such as frying French fries, grilling chicken wings, baking cakes, etc. In these preset modes, the fryer will automatically adjust the intensity and time interval of the hot air circulation according to the characteristics of the ingredients. Take French fries as an example. At the beginning, the fan will circulate hot air quickly at a high speed to quickly dehydrate the surface of the French fries to form a crispy crust; in the later stage of cooking, the fan speed may be appropriately reduced to prevent the French fries from being over-drying and ensure that the inside is cooked through and soft. This is achieved through the built-in smart chip, which stores a large amount of cooking data for different ingredients and automatically matches the corresponding hot air circulation program according to the mode selected by the user.
The air duct design of the air fryer also plays an important role in hot air circulation. Reasonable air ducts can guide hot air to be evenly distributed in all corners of the fryer to avoid local overheating or overcooling. Some high-end air fryers use a unique 360-degree surround air duct design. After the hot air is generated from the heating elements at the bottom or side, it circulates evenly in the fryer through the carefully designed air duct to ensure that every side of the ingredients can be evenly heated. At the same time, there may also be guide plates or baffles in the air duct to further optimize the flow direction and speed of the hot air and improve the accuracy of the hot air circulation.
Users can also make manual fine adjustments based on their own experience and preferences. For example, when baking some larger pieces of meat, if you find that the surface color is uneven, you can adjust the position of the fryer or manually adjust the fan speed to make the hot air circulation more in line with cooking needs.
Accurately controlling the hot air circulation during the cooking process of a home air fryer requires the synergy of temperature sensors, smart chips, reasonable air duct design, and appropriate manual intervention by users. Only in this way can the advantages of the air fryer be fully utilized to produce a variety of delicious and consistent food, bringing more fun and possibilities to home cooking.
