1, the higher the top temperature, the lower the temperature, the more hot air on the top of the roast duck stove, and the higher the temperature. In the process of baking, you can open the door regularly to dispel the hot air at the top.
2. Unreasonable use of fuel. Charcoal is too small, and it is easy to burn completely in a short time. After burning, the furnace temperature is insufficient, resulting in different temperatures. It is best to choose charcoal with high hardness and high density, which can maintain combustion for a long time without adding charcoal in the middle.
3. Pay special attention to the deviation of the wind where the roast duck furnace is placed, because too much wind will affect the firepower and temperature in the furnace, and will also deflect the flame, resulting in different temperatures in the furnace.
