What is the treatment method of kitchen fume in hotel?

If you want to get rid of the smell of kitchen fumes, the materials you use can be obtained at will, such as lemon residue, which is a great deodorant. You can also cut lemon residue squeezed from drinking black tea, or lemon that has been forgotten for a long time into thin slices or small pieces, and then put it in a pot and add water to boil. You can continue to add water to boil after boiling. At this time, the smell can not only remove the smell of lampblack, but also make the air full of pleasant fragrance. Alternatively, you can prepare a handful of green tea and a flat-bottomed pot. First heat the pot with fire, then fry the green tea on it and taste it. After a while, the indoor fumes and odors will be replaced by the fragrance of green tea!
