In fact, the use of millet oven is the same as other ovens. First, preheat the baking temperature to 200 degrees and set the baking time to 20 minutes. Irregular use of the oven will breed odor and bacteria, and preheating can remove odor and sterilize. In addition, if the food is directly put into baking without preheating, and the heating pipe is fully heated at this time, the food will face problems such as uneven heating, water loss, easy burning of the surface, and even lead to baking failure.
