空气炸锅这几年几乎是厨房小家电里最热的一类。它的原理并不复杂：顶部发热管加热，配合风扇把热空气高速循环，让食物表面快速脱水、形成酥脆外壳。本质上它是一个小体积、强对流的烤箱。
容量标注要看清楚
市面上的容量一般标 3 升、5 升、6 升不等，但实际可用量往往比标注小——因为食物不能堆满，必须留出热风循环的空间。判断标准很简单：
- 标注 5 升左右，实际一次能炸的薯条、鸡翅，大概是一人份到两人份。
- 如果你家常做两三个人的菜，建议选 5 升以上；一个人用，3 升够。
- 不要只看数字，看炸篮的形状和深度：又宽又浅的炸篮比又窄又深的更好用。
功率和使用
- 功率一般在 1200～1800 瓦之间。功率越大，预热和升温越快，食物更容易上色。
- 大多需要预热 3～5 分钟，尤其是做需要酥脆外壳的食物时。
- 别塞满：食物之间要留空隙，堆太厚会导致外层焦了里面还没熟，这是最常见的使用错误。
- 中途翻动：炸到一半拉出炸篮翻个面，受热更均匀。
- 少量油也能用（刷一层或喷一点），完全不用油的口感会偏干。
它适合做什么
蛋挞、鸡翅、薯条、烤蔬菜、复热面包和披萨，表现都不错。整只鸡、大块肉、需要汤汁的菜，就不太适合——这些还是交给烤箱或炖锅。它是”快速把小块食物做出脆皮”的工具，不是万能的。
清洁
每次用完，等机身冷却后把炸篮和底盘取出，用温水加洗涤剂清洗；多数炸篮涂层不粘，用软海绵别用钢丝球。加热管区域的油渍要定期擦，否则会冒烟、串味。
Air Fryers: Capacity, Power and Real Use
An air fryer is essentially a small, high-convection oven: a heating element plus a fan circulates hot air fast enough to crisp the surface of food.
Capacity labels can be misleading. Because food needs room for air to circulate, a “5 litre” basket realistically holds about one to two servings of fries or wings. For a household of two to three, choose 5 litres or more; for one person, 3 litres is enough. Look at the shape of the basket too — wide and shallow works better than narrow and deep.
Power typically ranges from 1200 to 1800 W; higher power preheats faster and browns better. Preheat for 3–5 minutes, never overcrowd the basket, and shake or turn the food halfway through. A light brush of oil gives a better result than none at all.
It excels at wings, fries, pastries, roasted vegetables and reheating bread or pizza. Whole birds, large cuts and anything needing liquid belong in an oven or a pot. Clean the basket and tray after each use, and wipe the heating area regularly.
