How can multifunctional mobile snack car be smoke-free? The traditional barbecue will produce a lot of smoke during the barbecue process, which will cause great pollution to the environment, while the smokeless barbecue car is designed and produced by a large equipment factory. The desktop is made of stainless steel, which is clean and easy to clean. The car body is made of iron plate, and the exterior is sprayed with antirust paint, which is firm and durable. The barbecue oven is a vertical barbecue. There are water tanks on both sides of the oven (water needs to be added) with iron plates on them to suppress the fire. Then there is an iron cover on it. When mutton kebabs are placed vertically in the oven, the kebabs will produce oil when roasted to a certain extent, and the oil will drip directly into the water tank, so that it will not produce smoky smell and will not cause harm to the body. Pressing the iron plate will transfer the hot air from the fire to the mutton skewers on both sides, and then cover them with iron covers, so that people can avoid hot air moxibustion to the greatest extent. Multifunctional mobile snack car is both environmentally friendly and hygienic.
