On the upper and lower tubes of the oven

The oven can be controlled independently up and down, but there is no domestic oven with this function yet. Most of them are industrial ovens, which are used in hotels, restaurants and western pastry houses. Because of the high production cost, if you use it at home, the price is high, for fear that customers will not accept it.

At most, families use the upper tube or the lower tube, but the disadvantages of this kind of use are much more. Because it takes a lot of power to heat a single tube to the temperature you set, too much flash heat in the already small oven will make the food burn quickly.

The only way is to add a barrier inside, which has slowed down and averaged the heat conduction, such as adding a cover on it or putting something under it.

It is very necessary to have a fan in the domestic oven, because the internal volume of the domestic oven is relatively small, so the temperature is uneven. Increase the fan to increase the thermal cycle, so that the temperature is uniform everywhere.

The cake is also well baked, because the steak is meat, and the baking temperature needs to be very uniform, otherwise the taste will be slightly worse.
