The general lampblack purifier mainly purifies lampblack, and the deodorizing effect is not very great. Some purifiers are equipped with ultraviolet lamps, which also have most deodorizing effects in use, but they can't completely deodorize. In order to achieve the real deodorizing effect, a special deodorizing device, an ultraviolet photolysis purifier, is necessary, which is generally like seafood and braised dishes, and has a strong taste. If the oil fume and odor are strong, it is necessary to match a device for removing oil fume and a device for removing odor in order to achieve real purification. If the smell is strong, it is impossible to achieve the real deodorization effect only by installing an oil fume purifier, especially in seafood and braised restaurants. In order to achieve the real deodorization effect, a deodorization device, namely ultraviolet photolysis purification, is added. After discussing with partners for a long time, I bought Shuangni, a smoke remover and a deodorizer, and now they are all installed. The effect of removing smoke and smell is ideal and quite satisfactory.
