The condensing speed is adjusted by the monitoring results of the first and second temperature detecting units 310 and 360. When the flue gas temperature is high, a correspondingly large condensation speed is required. The second temperature detection unit 360 serves as a correction parameter for detecting the gas component. Because the sensitivity of the sensor is different at different temperatures, a more accurate detection result can be obtained after the temperature parameter of the exhaust gas is corrected.

In the cooking process, temperature parameters of gas in each stage in the cooking process of the food materials are monitored through a temperature sensor, the carbon dioxide content of the gas in each stage in the cooking process of the food materials is monitored through a carbon dioxide sensor, the aroma value of the gas in each stage in the cooking process of the food materials is monitored through an aroma sensor, and the water vapor content of the gas in each stage in the cooking process of the food materials is obtained through a flow sensor and calculation. Whether the cooking process of the food materials is normally finished or abnormal is judged by monitoring the change of the parameters in each stage in the cooking process of the food materials so as to determine whether the parameters meet the corresponding preset values. For example, in the dehydration stage of the food material, the moisture of the food material does not reach the boiling point, and the corresponding gas parameters are less in water vapor, and the aroma and the carbon dioxide are less. In the food dehydration stage, water in the food materials can be rapidly evaporated, the steam amount is large, and at the moment, the corresponding gas parameters comprise more water steam, less fragrance and increased temperature. In the caramel reaction stage, the water vapor in the corresponding gas parameters begins to decrease, the carbon dioxide gradually increases, and when the carbon dioxide increases to a preset value, the next stage is carried out. In the Maillard effect stage, the water vapor is still less, the carbon dioxide is relatively reduced, the aroma value is increased, and when the aroma value reaches a preset value, the heating can be stopped. The gas parameters corresponding to each stage may be one or more of them. Whether each stage is completed can be determined by observing whether the key gas parameters of each stage meet preset conditions. And each stage of the food cooking process and the operation corresponding to the stage are controlled and realized by the main control unit of the cooker.
