The differences between ovens and air fryers include cooking methods, capacity, preheating, adding fat, etc.

1. Cooking method: The oven bakes food by heating air, while the air fryer bakes food by rotating hot air at high speed. Both cook differently.

2. Capacity: Ovens usually have a larger capacity and can accommodate larger foods, such as whole chickens, barbecues, etc.; air fryers usually have a smaller capacity and are suitable for baking small portions. food, such as French fries, chicken wings, etc.

3. Preheating: When using an oven to bake food, you need to preheat the oven, but using an air fryer does not require preheating.

4. Add grease: When baking food in an oven, you need to add grease or apply grease; but when baking food in an air fryer, you do not need to add grease.

Air fryer operating principle:

1. High-speed rotating hot air: There is a heating element and a fan inside the air fryer. When the heating element heats up, the fan will blow out the hot air. , and form a high-speed rotating hot air circulation in the pot.

2. Rapid heat transfer: The high-speed rotating hot air inside the air fryer can quickly transfer heat and quickly evaporate the moisture on the surface of the food, making the surface of the food crispy.

3. No need to add grease: Since the high-speed rotating hot air can make the surface of food crispy, there is no need to add grease when cooking food in an air fryer, thereby reducing the fat content in the food.
