The biggest benefit of hot air circulation is to achieve a more rapid and even heat in the oven, it is very suitable for roasting meat, but pastry baking is not suitable for use.

The reason is that the flow of air, although it can quickly equalize the heat of the entire furnace, but it will affect the temperature of the baking surface for a certain period of time, such as the figure above, the hot air circulation is on, resulting in the temperature of the furnace core dropped 10 degrees, of course, each machine performance may be different, but at least it shows that it is the temperature of the baking surface has an impact on the temperature of the baking surface, and this impact will cause some problems of the finished product, such as burned meat, baking, baking, baking, baking, and baking, and so on. Finished product production of some of the problems, such as burn color is too dark, etc., less use is better.

Roasted meat and so on, it is recommended to open, more energy-saving, burn color will be more uniform.
