What is an air sterilizer disinfection machine?
Air sterilizers used in food factories are devices specifically designed to purify and sterilize the air in processing environments. These air disinfecting machines use a variety of technologies to effectively eliminate air pollutants that can contaminate food, such as bacteria, viruses, mold spores, and other microorganisms. It helps extend the food shelf life and improve food quality.
Regulators around the world have recognized the critical role that air quality plays in maintaining a safe and sanitary food supply. In the United States, the Food and Drug Administration’s (FDA) Food Safety Modernization Act (FSMA) and Good Manufacturing Practices (GMP) require the installation of air sterilizing systems and the implementation of a comprehensive air quality monitoring program.
Similar regulations have been enacted in the European Union, with Health Regulation (EC) No 852/2004 setting clear guidelines for maintaining optimal air quality in food production facilities.

Some common types of air sterilizers used in food factories include:
1. Ultraviolet (UV) light disinfection systems:
- These systems use high-intensity UV-C radiation to inactivate and destroy the DNA or RNA of microorganisms, rendering them unable to replicate and cause contamination.
- UV light systems are typically installed in HVAC (heating, ventilation, and air conditioning) ductwork or as stand-alone units within production areas.
2. Ozone Generators:
- Ozone (O3) is a highly reactive form of oxygen that effectively oxidizes and kills a wide range of microorganisms, including bacteria, viruses, and fungi.
- Ozone generators produce ozone and disperse it throughout the production environment to disinfect the air.
3. Hydrogen Peroxide Vapor Systems:
- These systems produce a fine mist of hydrogen peroxide vapor that can penetrate and disinfect hard-to-reach areas.
- Hydrogen peroxide vapor effectively eliminates air and surface contaminants, providing comprehensive disinfection.
4. HEPA (High Efficiency Particulate Air) Filtration Systems:
- HEPA filters are designed to capture and remove extremely small suspended particles from the air, including microorganisms.
- These filters are often used in conjunction with other disinfection technologies to provide multiple layers of air purification.
The selection and deployment of air disinfection machines in food factories depends on various factors, such as the size and layout of the production facility, the specific microbiological risks, and the regulatory requirements of the area.

In which areas are disinfection machines mainly used in food factories?
In food factories, air disinfection machines are often deployed in the following key areas to maintain optimal air quality and prevent contamination:
1. Production areas:
- Air disinfection machines are strategically placed in major production areas, especially in semi-finished and finished food processing areas.
- These areas require the highest level of air cleanliness to mitigate the risk of airborne microbial contamination.
2. Packaging areas:
- Packaging lines and enclosures are key points where air disinfection is crucial, as packaged products are particularly susceptible to contamination.
- Air disinfection systems help maintain a sterile environment during the packaging process.
3. Storage and warehousing spaces:
- Food warehouses and storage rooms require effective air purification to prevent the growth and spread of mold, bacteria, and other contaminants that can cause stored products to spoil.
- Air disinfection machines play a vital role in maintaining the integrity of raw materials and finished products during storage.
4. Airlocks and transition areas:
- Areas where personnel, equipment, or materials transition between different production areas require strict air disinfection to prevent cross-contamination.
- Air disinfection machines in these areas prevent the entry of airborne threats.
5. Sensitive Processing Areas:
- Certain production processes, such as those involving ready-to-eat or perishable foods, may require more stringent air disinfection measures.
- These sensitive areas are deployed with dedicated air purification systems to ensure the highest levels of air quality.
By strategically positioning air disinfectors in these key areas, food factories can establish a comprehensive, multi-layered defense against airborne contaminants and safeguard the purity and safety of their food.

What Air Disinfection Machine Do We Have?

In high-risk food production areas, the need for effective air disinfection has never been more urgent. To address this critical challenge, We, a WONE manufacturer, have developed an innovative smart air disinfector that combines UV and ozone capabilities to disinfect and purify the air at the same time.
In the first stage, a high-intensity UV-C light chamber bombards the incoming air with germicidal radiation, destroying the DNA and RNA of airborne microorganisms, and making them unable to reproduce or cause infection.
“UV is a proven method for inactivating a wide range of pathogens, including bacteria, viruses, and mold spores,” Doe explains. “By exposing the air to this powerful disinfecting technology, we can significantly reduce the bioburden before the air enters the next stage.”
The second stage involves the generation of ozone (O3), a highly reactive form of oxygen that oxidizes and destroys remaining microorganisms. The ozone-enriched air is then circulated throughout the production environment, ensuring complete disinfection.
“Ozone is a complementary disinfectant that targets pathogens in a different way than UV,” Doe continues. “By combining these two disinfecting technologies, we create a synergistic effect that provides unmatched air purification performance.”
