1. Exhaust system
The external smoke exhaust system exhausts the oil smoke generated in the kitchen to the outside, and the smoke is exhausted through the smoke exhaust pipe. This way ensures the air quality in the kitchen and reduces the smell of oil smoke produced in the kitchen. However, this smoke exhaust method needs to invest more in smoke exhaust capacity and safety issues, and needs to be designed and built.
2. Circulating smoke exhaust system
The circulating smoke exhaust system can treat the air in the restaurant, absorb the harmful substances in the smoke, and then transport the treated air back to the restaurant again. Although this smoke exhaust method has certain advantages in saving energy and avoiding large-scale transformation, there are still some harmful substances in the discharged air, which is not conducive to human health and environmental protection.
3. Central smoke exhaust system
The central smoke exhaust system collects the lampblack and harmful gas in the kitchen into the smoke exhaust pipe, then purifies it by certain methods, and finally discharges it out of the room through the smoke exhaust port. This smoke exhaust mode can be expanded according to the passenger flow of the restaurant and the smoke volume of the kitchen in the later stage, which can purify the exhausted smoke efficiently and protect human health and the environment.
Generally speaking, each smoke exhaust method has its own advantages and disadvantages, and restaurants need to choose according to their own situation and budget. No matter what kind of smoke exhaust scheme, the smoke exhaust pipeline should be maintained and cleaned to ensure the smoke exhaust effect. I hope this article can help you understand the smoke exhaust mode of restaurant range hood.
