Advantages of UV disinfection technology

The disinfection effect of ultraviolet C disinfection technology on bacterial viruses and other pathogens has been recognized worldwide, and it has unparalleled bactericidal efficiency. The germicidal effect of ultraviolet rays on bacteria and viruses is generally within one second. For traditional chlorine and ozone methods, it takes 20 to 50 minutes to achieve the sterilization effect of ultraviolet rays. It has a broad spectrum of efficient sterilization, no secondary pollution, safe and reasonable design, safe and reliable operation. Simple maintenance and low cost. This equipment occupies a small area and has no noise. It can continuously sterilize in large quantities, and has a wide range of applications. 

Application

Ultraviolet disinfection technology is the latest generation of disinfection technology emerging in the late 1990s. It integrates optics, microbiology, electronics, fluid mechanics, and aerodynamics. It has the characteristics of high efficiency, broad spectrum, low cost, long life, large water volume and no secondary pollution. Mainstream consumer technology.

Mainly used to sterilize cooked food and water. Widely used in hospitals, food, Chinese herbal medicine, food and beverage processing and packaging equipment, health care products factory, food factory, dairy factory, brewery, beverage factory, bakery and packaging products factory, etc. The working principle of the equipment is that the ultraviolet sterilization band is mainly between 200-300nm, and the sterilization ability with the wavelength of 253.7nm is the strongest. When various bacterial viruses in water or air pass through the ultraviolet (253.7nm wavelength) irradiation area, ultraviolet rays penetrate the cell membrane and nucleus of microorganisms, destroying molecular bonds of nucleic acid (DNA or RNA), causing them to lose their replication ability or activity and die. To kill all bacterial viruses without using any chemicals. The germicidal lamp does not need to be converted into visible light, and the wavelength of 100-200nm can play a good sterilizing effect. This is because the cell has a regular absorption spectrum of light waves. Ultraviolet rays at 100-200nm have the greatest absorption. The absorbed ultraviolet rays actually act on the cell's genetic material, namely DNA. The energy is absorbed by the base pairs in the DNA, causing genetic material to mutate, causing the bacteria to die immediately or fail to reproduce offspring, thereby achieving the purpose of sterilization.

Maintenance and maintenance of UV sterilizer:
1 Regular inspection to ensure the normal operation of the UV lamp.
2. After continuous use for 8000 hours or one year, the UV lamp should be replaced. When replacing a new lamp, first unplug the lamp power socket and take out the ultraviolet lamp. Be careful not to touch the quartz glass of the new lamp with your fingers, as the stain will affect the intensity of the light. At the same time, carefully put the lamp into the interior of the sterilizer.
