Q： Does the whole factory need to be air disinfected entirely?
A: No. Air disinfection is usually carried out in areas with high cleanliness requirements, such as cooling rooms and inner packaging rooms for baking processing, which is based on risk assessment.
Q: How many air disinfection machines are configured in a workshop?
A: No matter what kind of machine the workshop equips, an ozone machine or an air disinfection machine with ozone and UV function, the number of units configured depends on several factors:
- The area of the workshop (for ozone disinfection, it is more precisely the volume).
- The partitions of the workshop. The partitions here do not simply refer to comprehensive partitions from top to bottom but also include the arrangement of obstacles, etc.
- The performance of the equipment itself. Because the concentration of ozone disinfection determines the effect of ozone disinfection
Q: How to choose air disinfection equipment from a hygienic perspective?
A: For areas where employees work for a long time, it is recommended to choose an air disinfection machine where people and machines coexist. The original intention of purchasing air disinfection equipment is to control microorganisms in the air. Just like the equipment needs to be cleaned regularly, the disinfection of air should also be maintained frequently. However, when the frequency cannot be guaranteed during the production process, real-time air disinfection is the best solution.
Q: How to choose air disinfection equipment from a maintenance perspective?
A: There are two principles for selecting air disinfection equipment from a maintenance perspective:
- Considering the time of workshop operations, the start and end times of production in different areas are different, and the operation of disinfection equipment should maintain full independence. Because most air disinfection equipment has an ozone disinfection function, and it takes time for ozone to take effect and allow personnel to enter.
- Consider the impact of maintenance on other disinfection equipment under normal operating conditions, if a centralized-split ozone disinfection system is used, other equipment may not be able to function due to the action of one generator.
Q: Does ozone disinfection solve mold problems?
A: Many experiments and literature have shown that appropriate ozone concentrations and operating times can effectively kill mold, etc. However, for food companies, it is more important to control the environmental conditions for mold formation, because mold has a strong reproductive ability.
Q: Can surfaces be disinfected during production operations?
A: In the production operation environment, there are people, raw materials, products, contact surfaces, and air. If the air disinfection equipment can disinfect the surface of objects during production operations, it usually means that it will have a certain harmful effect on people. Therefore, the air disinfection equipment with human-machine coexistence disinfects the air in a relatively closed container, rather than letting ozone diffuse into the entire space like ozone disinfection.
Q: Is it more convenient to use a mobile disinfection machine?
A: The convenience of mobile equipment lies in its availability everywhere. But we personally think that the symbolic significance of purchasing a mobile disinfection machine is greater than its actual use. So we don’t recommend to use the mobile disinfection machine.Because the mobile disinfection machine needs to be moved manually, and people can enter the space after ozone disinfection for at least half an hour after the disinfection is completed. This means that employees need to operate it many times at night to complete the air disinfection of various areas.
Q: Can air disinfection be used to replace the irradiation?
A: The mechanism of gas-phase ozone disinfection is different from that of irradiation, and they cannot be replaced by each other. The environmental factors that affect the sterilization effect of gas-phase ozone are mainly temperature and humidity. Generally speaking, the killing effect is better when the temperature is low and the humidity is high. At present, ozone water cooling sterilization is also used on the market. But for air disinfection equipment, it is not enough to control the overall microbial level of the product.
