How to balance the oven temperature of roast duck to make it?

First of all, the temperature control of Guangdong roast duck is the key, but the choice of furnace also helps to keep the temperature constant. Barbecue ovens are divided into double-layer ovens and single-layer ovens, and their difference lies in the different heat preservation performance. Double-layer furnace has good thermal insulation performance, stable constant temperature control and better high temperature regulation of single-layer furnace. As long as reasonable carbon is added, it can be directly raised to high temperature, and the temperature adjustable range is relatively large. Now many barbecue shops use this kind of single-layer stove, and the price is relatively cheap. Secondly, the temperature control of Guangdong roast duck in the furnace also comes from the rational use of charcoal. If the hardness of charcoal is different, the temperature during barbecue is also different, so charcoal is divided into high-temperature charcoal and low-temperature charcoal. Firepower needs to be constant. Choose fire-resistant and bulky charcoal. If charcoal is too broken and easy to burn, it will lead to high temperature in the early stage and low temperature in the later stage. In the middle and late stage of firing, carbon with high hardness should be selected. This kind of carbon is obviously flame-resistant and does not need to be added halfway. In the process of baking, the types of carbon used in the early, middle and late stages are different, and the dosage is also different. To roast a pot of roast duck well, the control of charcoal burning needs a certain technical content, which not only controls the effect of roasted products, but also effectively controls the cost. In a word, "save costs and burn technology well".

There is also a heat formula for oven temperature of Cantonese crispy roast duck. The principle is: the heat released by charcoal combustion+the heat absorbed by oven+the heat absorbed by roasted green embryo is equivalent to what we usually call balance of payments. What we need to do now is to keep the heat balance. Actually, the operation is very simple. As long as we apply the income formula to our calorie formula, we can use it. This analogy method can also be used in other aspects. Finally, the damper of Cantonese crispy roast duck furnace is properly controlled. It is particularly important to note that the oven cannot be placed in an environment with excessive wind, and the flame will shift in the circulation of the wind, resulting in unstable temperature in the oven. Therefore, when maintaining the furnace temperature, we should pay attention to the furnace as the most critical issue, as well as the quality, size and combustion of carbon placed in it.
