Air Purification For Manufacturing Flavorings and Seasonings
The industrial production of spices and aromatics is constantly gaining importance. Their production often produces a strong odour, which can be reduced by the use of cold combustion
The work “flavor” indicates a specific odor or taste that is caused by individual chemical components or by a mix of substances in products such as food or medicines. The source of many flavors are chemical compounds (i.e., flavorings) belonging to the categories of aromatic compounds, terpenes, esters, alkylpyrazines, aldehydes, or ketones (see the “aroma value” concept for examining flavorings in food).
The production of flavorings is becoming increasingly important from an economic perspective. Thermal process flavorings are created using controlled heating of additives with sugar and nitrogen content (e.g., glucose with beef extract). The flavoring is created by heat the same as when bread is baked or meat is roasted, for example.
Smoke flavorings are created when smoke condenses in water, i.e., when the smoke is trapped there. When manufacturing smoke flavorings, the producer must maintain and strictly monitor specific legal conditions concerning temperature, water content in wood, and air supply.
Biofilters or afterburning systems have long been been used for the processes listed above. However, biofilters in particular take up a great deal of space and are very sensitive to air temperature and humidity; afterburning systems are primarily marked by high energy costs. In contrast, UV-C ozone technology is a significantly more environmentally friendly method. The modular exhaust purification system eliminates odors and, in combination with an air scrubber, even eliminates smoke odors from smokers for hot and cold smoking.

Operating costs are very low in comparison with the costs for afterburning. Savings of 80% can be realistically expected. The high level of separation efficiency ensures compliance with emission threshold values in accordance with TA Luft and VDI standards. Maintenance costs are low, because the exhaust purification system is not subject to thermal degradation.
