In production and processing, food processing companies are prone to produce a lot of organic industrial waste gas containing peculiar smells such as hydrogen sulfide, esters, ethers, aldehydes, etc. foul odour will also accompany it. Food additives are compounds and natural substances added to food to improve the colour, aroma, and taste of food and the needs for anti-corrosion and processing technology. At present, there are 23 types of food additives in my country, more than 2,000. Still, in the waste gas treatment, the waste gas generated during the production or use of a particular food additive is generally targeted.


The rapid development of the food industry has led to a rapid increase in the scale and number of food factories. Different kinds of peculiar smells and waste gas will be generated during food production and processing. These odd smells and waste gas will endanger the health of workers and pollute the environment. Therefore, the treatment of strange smell and waste gas in food processing plants is essential. Waste gas treatment solutions for food processing workshops:

Composition and hazards of waste gas in food processing workshops

The main components of waste gas from food processing workshops are methyl methacrylate, ethyl acetate, ethyl acetoacetate, aldehydes, ammonia, trimethylamine, hydrogen sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, etc.; these waste gases will cause serious harm to human health and the ecological environment. It may cause discomfort, headache, dizziness, nausea, vomiting, loss of appetite, and lack of concentration in mild cases. In severe cases, it may affect the human respiratory system, circulatory system, and digestion. The design and the reproductive system cause different degrees of toxicity. Aromatic compounds such as benzene, toluene, styrene, etc., can also cause distortion and cancer in the human body. Therefore, waste gas treatment in food factories is essential.

The waste gas treatment process in the food processing workshop

Food waste gas treatment considers operating costs and safety. The process route of this plan is planned to adopt "ventilation system (fan, collection cover, pipeline) + pretreatment system (water spray) + core purification system (UV photolysis purification equipment)". Food waste gas treatment.


The first stage: the exhaust gas passes through a wet scrubber to remove the ammonia, alcohol and other easily soluble components and dust in the exhaust gas, and then enter the next process.

The second stage: the exhaust gas enters the core purification system (UV photolysis purification equipment). UV photolysis purification equipment cracks the sludge odour, and at the same time, decomposes oxygen and produces ozone. The ozone and organic molecular cracking products undergo oxidation-reduction reactions, and finally, carbon dioxide, water and other substances are generated and then discharged through the pipeline at high altitude.

China Xicheng has its own exhaust gas treatment R&D team and experts, equipment production lines, and the whole process of R&D, design, production and sales is selected as a national high-tech enterprise. Our later operation energy consumption and ease of use are better than those of our peers. We resolutely adopt the basic principle of one enterprise, one policy to achieve genuinely customized products. The same effect can also be unique and perfect in the functional design of different industries. The front-end smoke and dust control and the end-end oil mist exhaust gas and odour control can be effectively combined and designed to provide you with a complete set of industrial waste gas treatment projects.
