It is necessary to install a range hood in the hotel. Without this, you can't even pass the audit.
When cooking at home at ordinary times, some oil fume and waste gas will be produced, which will do harm to our human body and the atmospheric environment. Therefore, almost all families have installed a range hood, through which the fume exhaust gas is discharged out of the window, so as to prevent the family from being harmed by the fume. However, most range hoods have no purification function, and a few range hoods have certain purification function, but they do not meet the commercial purification standards. And the country will not strictly investigate the problem of soot produced by families in daily life.
For large-scale commercial kitchens such as restaurants, hotels, or food processing plants, it usually runs for a long time and continuously produces a lot of oil fume. If you use a range hood, there is no purification effect at all. If you pump out the lampblack, it will be directly discharged outdoors, which will seriously pollute the atmospheric environment and the health of the surrounding residents. In recent years, the catering service industry has produced a large amount of soot, and now environmental protection departments all over the country are carrying out rectification successively. Therefore, the catering service industry has always been required to install fume purification equipment so that the fume emission standard can operate normally.
