The revolving container helps to stir, turn, and squeeze the meal according to the temperature and time. The spinning container rotates to the opposite side after the food has been cooked and turned.

On the other hand, the fan is used to circulate the heat around the meal in a similar way to a conventional oven. The heated air is then circulated and moved upward. To properly prepare meals, an air fryer circulates hot air around the meal.
