Hot Air Convection Mode:
1, when baking cookies can make the temperature around the cookies evenly, and the hot air convection function will make the cookies crisp and dry faster.
2, you can turn on the hot air mode in the low temperature gear, used to dry things, such as making dried dates, banana slices and so on.
3.Roasting meat can enhance the heat penetration effect.
But the hot air convection mode is not suitable for baking cakes, don't turn on the hot air mode when baking a cake, the hot air will take away the moisture on the surface of the food, so that the baked cake will become drier.
The oven with hot air circulation can effectively make the heat in the oven flow evenly, with hot air mode fermentation will make the fermentation more evenly, with hot air baking will make the surface of the macaron faster crust. There is also baking bread, cookies and other desserts, if the surface has been colored, and the middle is not cooked, you can choose to lower or turn off the upper fire temperature, and use the lower fire to heat the air mode to bake, in order to avoid the color is too dark or baked.
The answer applies to most oven models from Midea, Gree, Haier and others.
