The reason is:?
1, the combustion efficiency of household stoves is low, and the exhaust equipment of household stoves is not enough to ensure the complete discharge of waste, which is a potential danger of gas poisoning.
2. Domestic natural gas is mainly produced by petroleum, natural gas or coal chemical industry, and generally contains components such as methane and coal tar. It is toxic when it comes into contact with food, and some even have a greater risk of cancer.
3. Generally, there is no grease collection function in the cooker, and the grease dripping from the barbecue is easy to cause external fire, and improper handling will cause fire.
4. High-voltage electrostatic (plasma) is to separate charged dust particles from gas by gas ionization and electric field force under high pressure. If it is not cleaned according to the specifications, the oil accumulation in the smoke exhaust pipeline is serious and the fire risk is great. ?
5. One or more combinations of physical filter screen, activated carbon and steel wire. At present, only imported ultraviolet lamps can guarantee the reliability and durability of products.
Extended data:
1. BBQ: BBQ can be divided into three types: charcoal stove, gas stove and electric oven, among which gas stove and electric oven are popular because they have no oil smoke and no pollution to products. The common types of barbecue ovens in the market are apple oven, rectangular oven, portable oven and so on. Apple oven has the most pleasing appearance, rounded outline and large capacity. Generally, it is separated by two layers of cover nets, which are used for stewing and smoking respectively. Moreover, there are wheels and handles, which are convenient for changing positions at will during the barbecue process, showing the exquisiteness and thoughtfulness of the owner.
2. Barbecue car: Because the street stall take-out barbecue oven is inconvenient to carry, the barbecue car has become the mainstream barbecue tool for street stall take-out. It can be moved. You can open it by preparing a can of gas and barbecue materials. Low cost, becoming the first choice for small investors. And now there are more and more popular barbecue cars on the market. Besides barbecue, you can also make mala Tang, hot and sour powder and so on.
3. Barbecue charcoal: Common charcoal on the market includes combustible charcoal, charcoal and machine-made charcoal. Combustible charcoal is available in outdoor stores and is divided into square and cake shapes. There is a combustible layer on the surface of combustible charcoal, which is easier to ignite than ordinary charcoal. The disadvantage is that it is more expensive, and a small box costs more than 100 yuan. The price of 4 kg of ordinary charcoal is only 20 yuan, but the inside varies in size, which easily leads to uneven firepower and short burning time, so charcoal must be continuously added during baking.
Machine-made charcoal is actually a mixture of charcoal and coal, pressed into a hollow polygon, and the composition of coal can be seen from charcoal ash. This kind of charcoal has the advantages of uniform size, long burning time, uniform firepower, no smoke and low price. Many professional barbecue shops choose this charcoal, but the ignition process is laborious.
