The difference between oven and air fryer lies in different processing principles, different volumes and different fuel consumption. Air fryer is actually a kind of oven, which uses high temperature to heat air, and then cooks the whole ingredients from outside to inside through high temperature air. But the most essential difference between the two is the difference in heating principle! The air fryer is like a small air furnace. Through the rapid circulation of hot air, it forms a heat flow in a closed small space and heats it quickly. Because hot air can take away the moisture on the surface of food, baking can make a similar "frying" effect. Its capacity is smaller than that of the oven, and its function is less, but the temperature rises faster, so that the skin of the ingredients will have a crisp taste, and it can achieve the effect of oil-free frying, which is healthier. The oven is different. Generally, the upper and lower heating pipes are used, and the temperature is accurately controlled by the temperature sensing probe. The temperature control function is stronger than that of air fryer, and it can make more kinds.
