Air fryer, when the air fryer was first born a few years ago, the price was really scary. In recent years, domestic chefs' electric brands have also started to make air fryers, which has also made Philips air fryers go down the altar, but Philips' technology in this field is still the industry leader. The air fryer is actually an oven. It uses the principle of hot air circulation to cook food. Its advantages are no need for preheating and high heating speed. At the same time, it can reduce the guilt of no oil (less oil). The disadvantage is that cooking will still have oil smoke (pay attention to smoke exhaust), and the capacity is much smaller than that of the oven.
