Kitchen exhaust fumes contain a variety of pungent odors, including acidic, spicy, and burnt smells, along with over 300 types of harmful substances and carcinogens. These fumes are a major source of PM10 (particulate matter smaller than 10 micrometers) and volatile organic compounds (VOCs) in the atmosphere. Not only do they pose serious health risks, but they also contribute significantly to atmospheric pollution. As a result, addressing oil fume pollution has become a national priority. Many regions now require local restaurants to install fume purifiers. However, even with these devices in place, some businesses still struggle to meet emission standards. Why is this happening?
One key issue lies in selecting a dependable fume purifier brand. Brands like Langxia and Shuangni offer reliable solutions. Another critical factor is ensuring the air volume capacity of the purifier matches the needs of your kitchen. Air volume is measured in cubic meters per hour, so a 4,000 cubic meter per hour system can process 4,000 cubic meters of gas in an hour. Langxia, for instance, offers various models with air volumes ranging from 4,000 to 64,000 cubic meters per hour. Different kitchens require different air volumes based on their size and cooking style.
For Cantonese cuisine, which typically involves lighter flavors and less oil usage, the air volume requirement tends to be lower. A general guideline is to multiply the number of stoves by 3,000 cubic meters per hour for effective fume purification.
In contrast, cuisines like Hunan and Sichuan rely heavily on high-heat cooking, frequent stir-frying, and generous oil use, leading to higher fume production and stronger odors. These kitchens usually need an air volume of 4,000 cubic meters per hour per stove.
Barbecue joints generate particularly harmful fumes due to the interaction between charcoal fires and grease. High oil accumulation on grills and trays results in significant fume emissions, necessitating an air volume of 6,000 cubic meters per hour per meter of grill length.
School and corporate cafeterias often feature large pots, producing extensive fumes that require robust purification systems. For example, each large pot typically requires 8,000 cubic meters per hour, meaning two pots would need a combined air volume of 16,000 cubic meters per hour.
Proper air volume matching ensures optimal performance of the fume purifier. Langxia’s purifiers use advanced technology, including an 18KV high-frequency intelligent power supply and cylindrical cellular electric fields, achieving purification efficiencies exceeding 98%. This ensures compliance with regulatory standards across different regions.
Remember, always consult professionals to customize your system to match your specific kitchen needs. Properly sized and maintained fume purifiers protect both health and the environment while meeting legal requirements.
