First of all, briefly introduce the familiar oven. Ovens are also known as commercial open hearth furnaces in the industry. The structure of domestic oven is similar to that of open hearth furnace. Generally, the open hearth furnace is heated by upper and lower tubes, and different temperatures can be set. The temperature of open hearth furnace is slow, so it must be preheated before baking to reach the ideal temperature. Therefore, if the recipe stipulates that the upper and lower fires should be used at different temperatures, it is best to make them in the oven. The open-hearth furnace can only bake one dish on one floor, so as to spread it evenly. For example, the home oven at home can only be placed in the middle floor.

PS: Commercial soft toast slices (toasted and sliced toast), if you want to continue baking in the oven and make the bread crispy on the outside and soft on the inside, I suggest that you put it in a home oven without preheating, and it will be ready in about170℃ for 2 ~ 5 minutes! The preheating step is completely saved!

Where is the air furnace better than the open hearth furnace? Just heat it evenly, the high-temperature airflow in the furnace keeps blowing, and the food is evenly colored. Unlike the open hearth furnace, which can only bake intermediate food, you can bake several plates of food continuously to ensure uniform coloring. This is the power of the wind furnace.
