烤箱的熱風循環(huán)有什么作用？
What is the function of hot air circulation in the oven?
熱風循環(huán)一般分為兩種，一種是背部有發(fā)熱管的，可以直接吹出熱風來；另外一種是只有風扇的。
Hot air circulation is generally divided into two types. One is that there is a heating pipe at the back, which can directly blow out hot air; The other is fan only.
熱風循環(huán)最大的作用就是攪拌烤箱內(nèi)腔空氣，使得烤制的時候溫度更均勻，防止食物局部烤焦。
The most important function of hot air circulation is to stir the air in the oven to make the temperature more uniform during baking and prevent local food from scorching.
熱風循環(huán)雖然做不到空氣炸鍋的那種空氣炸效果，但是熱風會帶走食物表面的水分，可以使食物更加焦脆，做出外教內(nèi)嫩的口感。
Although the hot air circulation can not achieve the air frying effect of the air fryer, the hot air will take away the water on the food surface, which can make the food more crispy and make the taste tender for foreign teachers.
