How long does it take for UV Light disinfection in different fields?

The application of ultraviolet technology in the field of disinfection has gradually become popular. With its advantages of high efficiency and reliability, ultraviolet disinfection lamps are widely used in fields such as homes, healthcare, food, cosmetics, and water treatment. However, the efficacy of ultraviolet lamps is not determined by the duration of use, but rather by calculations and arrangements based on different fields.

Medical industry

The medical industry is one of the important application fields for ultraviolet lamp disinfection. Medical equipment, operating rooms, air, surfaces, etc. all require ultraviolet disinfection. The disinfection time varies depending on the size and classification of the equipment. Usually, using 254nm ultraviolet disinfection lamps for relatively small medical devices takes only 10-20 minutes to complete, while large equipment and operating rooms require the use of multiple tubes or lamps in combination. Depending on the size, layout, and supplementary air circulation conditions of different equipment, it generally takes 30 minutes to 2 hours.

Food industry

In the food processing industry, the requirements for environmental hygiene are very high, and the disinfection requirements for bacteria and viruses are also very strict. The disinfection of ultraviolet lamps in food processing environments requires attention to different types of food and the level of cleanliness. In general, the UV Lights on the surface of the food processing area needs to be used for at least 30 minutes, and the UV Lights on the ceiling needs to be used for 60 minutes, with an ambient temperature not exceeding 50 ° C.

In summary, the disinfection time of ultraviolet lamps varies in different fields and needs to be determined based on specific circumstances. The disinfection time is not as long as possible, but should be calculated comprehensively based on multiple factors such as equipment size, power, number of light tubes, program used, environment, and working state. When using ultraviolet lamps for disinfection, it is also necessary to pay attention to safety measures, safety distance and time, to prevent damage to the human body or equipment.
