Detailed Description
The following describes an embodiment of the intelligent barbecue mode switching system of the present invention in detail.
In barbecue, the best choice of fuel is charcoal, and chemical charcoal is not used as much as possible. The special flavor of charcoal-roasted food comes from the aroma of charcoal-roasted food at high temperature, and therefore, the choice of good charcoal is the basis for enjoying the delicious taste. The charcoal fire with good quality generally has long burning time and good fire behavior. The charcoal is preferably selected from branch parts, and whole tubers are not used, otherwise the charcoal is not easy to be ignited. At the time of ignition, 5 capsules are put in one pack of fire seeds at a time. When the charcoal is burnt to be transparent red and hot, the charcoal is spread and baked, and when the surface layer of the charcoal is not completely burnt, the charcoal is not baked quickly, so that the food is easily dirtied and blackened.
Before roasting food, a layer of oil is brushed on the grill to prevent the food from being stuck on the grill. The residues on the grill are brushed away by the iron brush at any time, the grill is kept clean, and the flavor of the food cannot be influenced.
