Hotel lampblack machine is one of the important equipment in the hotel kitchen, which can effectively absorb the lampblack, reduce the harm to the kitchen environment and people, ensure the food quality, and meet the hygiene standards. However, the lampblack machine has been used for a long time, and the accumulation of oil pollution is serious, which not only affects the performance of the lampblack machine, but also produces odor and microorganisms, which affects the dining environment and food safety. Therefore, the lampblack machine in the hotel needs to be cleaned and maintained regularly.

there are two aspects to deal with the lampblack of the hotel lampblack machine: cleaning and maintaining the lampblack machine itself, and preventing and controlling the lampblack emission. The specific treatment measures are as follows:

1. Clean and maintain the range hood itself:

(1) Clean the filter screen and oil cup of the range hood regularly: the filter screen and oil cup of the range hood are the key components for separating and collecting oil fume and grease. If they are not cleaned and replaced regularly, the operating efficiency of the range hood will be reduced, the oil fume will not be easily discharged, and even a fire will be caused.

(2) clean the inner wall and air duct of the range hood: the oil, dust and mold inside the range hood also need to be cleaned regularly to avoid heavy pollution.

(3) technical maintenance and regular overhaul: the range hood needs regular technical maintenance and overhaul, and if problems are found, it should be repaired or replaced in time to ensure the normal operation of the range hood.

2. Prevention and control of lampblack emission:

(1) Reasonable installation and use of lampblack machine: The lampblack machine should be installed as close as possible to the stove to ensure that the lampblack can be discharged in time and avoid the backlog of lampblack. Moreover, the switch range hood should be used reasonably to avoid turning on the range hood while heating, otherwise the lampblack will be sucked back into the room.

(2) prevent the oil fume from leaking: the oil fume discharged by the range hood also needs to be prevented and controlled, and a protective net should be set at the smoke outlet. At the same time, hotels should also pay attention to the standardized use and maintenance of ventilation facilities such as kitchens and flues.

(3) Installation of fresh air system: A fresh air system should be installed at the same time as the smoke exhaust system, so as to circulate the indoor air and avoid being deposited indoors and affecting the dining environment.

in a word, for the cooking fume treatment of restaurant range hoods, besides regular maintenance and cleaning of the range hoods, prevention of the return of cooking fume, some high-tech cooking fume purification equipment, such as electrostatic cooking fume purification equipment and pyrolysis purification equipment, can be adopted to improve the cooking fume purification efficiency and reduce the harm to the environment and human body.
