Air Fryer

Advantages of Air Fryer:

(1) If the air fryer is placed in the family kitchen, the floor area is not particularly large, because the oven may occupy a lot of places, but the air fryer will never occupy a lot of places. Compared with an Electric Rice Cooker, the air fryer will be larger, but it is very convenient to move in practice.

(2) When making the air fryer, it is easy to make food for only two people, and it can also meet different needs. Unlike real fried food, because it is such a large pot of oil, it basically needs to fry a lot of things when cooking again.

(3) When the air fryer is used, you can directly pour out all the utensils and things inside, and then put a rag on the air fryer, or do it again with some clean wet paper towels. In this way, the air fryer is very convenient to clean.

(4) The air fryer has its own control system. In addition to shaking at the beginning, it basically doesn't need to be looked after. When the temperature is too high, the machine will adjust automatically, and there can be no Hu frying phenomenon. As long as the relevant time is set, this mechanical equipment will turn off automatically at the time point of the air fryer.
