How is the temperature control of the adjustable electric air fryer achieved

Among modern kitchen equipment, adjustable electric air fryers are popular for their efficient and convenient cooking methods. One of its core technologies is the temperature control system, which is designed to ensure that ingredients are cooked at the optimal temperature to achieve ideal taste and nutrient retention.

Basic principles of temperature control
The temperature control system of an adjustable electric air fryer is mainly composed of a temperature sensor, a control circuit, a heating element, and a fan. The temperature sensor is responsible for real-time monitoring of the internal temperature of the fryer and feeding the information back to the control circuit. The control circuit compares the preset temperature value with the real-time temperature value, and then adjusts the power of the heating element and the speed of the fan to ensure accurate control of the internal temperature of the fryer.
Temperature sensors usually use thermistor or thermocouple technology, which can react quickly when the temperature changes and change its resistance or voltage output. This highly sensitive design allows the air fryer to quickly adapt to different cooking needs and ensure uniform heating of food.
As the core part of the temperature control system, the control circuit receives the electrical signal from the temperature sensor and compares it with the temperature set by the user. When the actual temperature is lower than the set value, the control circuit will issue a command to start the heating element; conversely, when the actual temperature exceeds the set value, the circuit will cut off the power supply of the heating element or reduce its power to prevent the food from overheating.
The heating element is the main heat source of the air fryer, usually in the form of electric heating wire, electric heating tube or heating film. By accurately adjusting the power of the heating element by the control circuit, the air fryer can reach the required cooking temperature in a short time, thereby improving cooking efficiency.
The fan also plays an important role in temperature control. It not only accelerates the circulation of hot air to ensure that the food is heated evenly, but also effectively dissipates heat after cooking, reduces the internal temperature of the fryer, and prolongs the service life of the equipment.

Implementation of temperature control
The temperature control of adjustable electric air fryers usually includes three key steps: preset temperature setting, real-time temperature monitoring and automatic adjustment.
In the preset temperature setting stage, the user enters the desired cooking temperature through the operation interface (such as a touch panel or a smartphone application). This process includes selecting a cooking mode (such as baking, frying, baking, etc.) and setting a specific temperature value to ensure that the device can cook according to the user's needs.
During the real-time temperature monitoring stage, the temperature sensor continuously monitors the temperature inside the fryer and converts the data into electrical signals and transmits them to the control circuit. The control circuit determines whether the power of the heating element needs to be adjusted based on the comparison between the real-time temperature and the preset temperature.
During the automatic adjustment stage, the control circuit automatically adjusts the power of the heating element and the speed of the fan based on the comparison results to ensure accurate control of the temperature inside the fryer. If the actual temperature is lower than the preset value, the control circuit will increase the power of the heating element; otherwise, the power of the heating element will be reduced or the power will be cut off, and the fan speed will be increased to accelerate heat dissipation.
