The commercial kitchen when working creates airborne grease, fumes, odor and that nasty steam that makes the kitchen cloudy. How to remove fumes and odor in the commercial kitchen?
Hood is installed above kitchen stoves or cooking areas, connected to a exhaust system with a blower (extractor fan) will suck fumes and odor out of the kitchen and discharged in the designed position.
So, the exhaust system does the job of cleaning the air in the restaurant kitchen, creating a good working environment for kitchen staff.
But smoke and odor are still released after being sucked out of the system into the environment, causing air pollution and harming human health. (read more about “The harm of fumes pollution in catering industry” The odor from the restaurant kitchen is mixed in the soot, which brings a lot of harm to people’s normal life.some
Fumes contains lampblack, cooking oil can be purified by some kind equipment such as ESP (Electrostatic Precipitator) fume purifier, active carbon, by water in high result, approximately 98% if purify by ESP.
But the odor are organic molecules that cannot be thoroughly treated with above equipment. How to treat the odor from kitchen?
The methods to treat the commercial kitchen odor are UV light or industrial ozone, or Titanium dioxide filters. There are various ways of applying UV or Ozone or UV + Ozone, or UV + Ozone + Titanium dioxide filters
- UV light has high energy that can break chemical bonds and break larger molecules into smaller molecules, breaking the bonds of fat compounds by breaking them down into simpler molecules. Consequently, the odor after treating using a UV device is the breaking of these bonds during sterilization. Installing UV device together with ESP on the commercial kitchen exhaust system can purify up to 98% odor and fumes. (The UV light in this case is UV C). UV – C has bactericidal properties.
- Ozone reacts with odor molecules by transferring the “extra” oxygen atom of the ozone molecule to the odor molecule, changing its composition so it no longer has the same chemical makeup. This chemical reaction is called oxidation. Because Ozone is a tiny molecule which is composed of three oxygen atoms. It is highly reactive which makes it an unstable and potentially toxic gas. It is important to make sure that the Ozone has completely “turned back” into oxygen before the air comes out in the street. Usually a few meters of tube are required for this to happen, or an active carbon filter must be install at the end of the tube.
