The reason for the large exhaust volume of catering range hoods

Catering range hoods are essential equipment in restaurants, hotels and other places. Their function is to discharge harmful gases such as oil fumes, heat, odors and other gases generated in the kitchen to ensure clean, hygienic and comfortable kitchen air. Exhaust air volume is an important indicator to measure the quality of catering range hoods. Generally, the exhaust air volume is required to be greater than a certain value. The reasons for large exhaust air volume are as follows:

1. The restaurant kitchen environment is complex. . There are many cooking utensils and high firepower in the kitchen, coupled with the rapid movement of operators, the oil fumes and heat in the air will be quickly discharged. If the exhaust volume is not large, it will be difficult to effectively remove pollutants in the kitchen, affecting the comfort of the operating environment. and hygiene levels.

2. Various cooking methods. The types of cooking utensils and cooking methods in the kitchen vary widely, such as frying, stir-frying, roasting, boiling, stewing, etc. The operation requirements are different, and the forms of the air outlets are also different. These factors must be taken into account when designing the exhaust volume of the range hood to ensure that it Can effectively absorb and discharge different oil fumes and pollutants.

3. Pressure loss. As the fan discharges at higher and higher speeds, the air flow velocity will increase accordingly. In this case, if the exhaust volume of the range hood is not large enough, it may cause pressure loss and prevent the oil smoke from being discharged smoothly, thus affecting the cleaning effect of the range hood and easily causing environmental pollution and fire hazards.

4. Operator needs. In order to ensure the comfort and safety of operators in the kitchen, it is often necessary to design the air outlet at a higher position to maximize the discharge of oil smoke and hot air. As a result, the exhaust volume must be increased in order to improve the exhaust efficiency and reduce the operator's work intensity.

To sum up, the large exhaust volume of the catering range hood is to ensure the environmental safety and hygiene of the kitchen, and at the same time to increase the author's work comfort and efficiency. Therefore, when purchasing and designing the range hood, These factors must be fully considered to determine the appropriate exhaust volume standard.
