Summer is the season of barbecue. At night, there will be a smell of barbecue in the air, which will make Bian Xiao drool. Seeing that some waste materials at home are very suitable for charcoal barbecue, I immediately turned waste into treasure and made a simple charcoal barbecue. Although the appearance of the finished product is not satisfactory, it has not affected its use effect at all. Now let's introduce its production process.

The first step is to prepare the materials. I used waste materials from home: a big iron bucket of cooking oil, two old iron partition nets in the refrigerator, and four sets of 8cm screws and nuts. In addition to making the main material of charcoal barbecue, we should also prepare tape measure, marker, iron scissors and electric drill.

The second step is to make a barbecue net. Tie two refrigerator partition iron nets together with iron wire to ensure the durability of barbecue nets. It is best to tie two iron nets alternately when binding, so that small fresh meat will not fall into the carbon pile when using.

The third step is to manufacture the furnace body. Because the cooking oil iron drum prepared before is square, one side of it is cut open with special iron scissors to form an open three-sided iron stove. Before cutting, mark the cutting line to be cut on the iron drum. After cutting off one side of the cylinder, trim the cutting opening with pliers. Although we sometimes use charcoal barbecue ovens made of waste materials, we still have to ensure its beauty.

The fourth step is to install the carbon grid. After measuring the internal size of the box, cut the refrigerator grid prepared before according to the measured size. After cutting, the carbon grid should be put into the furnace body for testing, and try to fit the furnace body as much as possible. After cutting the carbon grid, put the four 8cm screws and nuts prepared before on the four corners of the carbon grid. The carbon grid with screws is directly placed in the furnace body.

Step five, make ventilation holes. In order to make the charcoal burn fully in the furnace, we need to open the tuyere of the charcoal barbecue oven. At this time, it is necessary to use the electric drill prepared before, and use the electric drill to make two ventilation holes on both sides of the furnace body. This will ensure the oxygen needed for charcoal combustion.

At this point, a homemade smokeless charcoal barbecue oven was completed. After doing well, Bian Xiao immediately conducted experiments on his own outdoor balcony. In the baking process, there is no phenomenon that carbon can't burn, and there is no excessive smoke. The experiment was a complete success. I summed up the key points of production: first, the carbon grid must be treated with a strong iron grid, and plastic must not be attached to the iron grid, which is not good for your health. Second, the vent must be located in the middle of both sides of the furnace body to prevent smoking during barbecue.
