(1) Product Introduction:

UV sterilization technology integrates optics, microbiology, electronics, fluid mechanics, and aerodynamics, and is internationally recognized for its high efficiency, broad spectrum, low cost, long lifespan, large water volume, and no secondary pollution21One of the mainstream disinfection technologies of the century.

UV sterilization machines are widely used in hospitals, food, herbal medicine, food and beverage processing and packaging equipment, health product factories, medical products, food factories, cosmetics factories, dairy products factories, breweries, beverage factories, bakeries, and packaging product factories.

(II) working principle:

Ultraviolet radiation is between visible light andXThe electromagnetic spectrum between rays,200nmto400nmThe ultraviolet spectrum has a strong bactericidal effect, which is240~280nmWithin the range (with its peak value at)265nm）The most destructive bacteria and virusesDNA(Deoxyribonucleic acid) orRNAThe molecular structure of ribonucleic acid has the ability to cause growth cell death and/or regenerative cell death, thereby achieving the effect of sterilization and disinfection. The main wavelength of discharge radiation from low-pressure mercury lamps is253.7nmIt is located in the ultraviolet band with the strongest bactericidal effect, so it is widely used in the industry254.7nmThe ultraviolet mercury lamp is used as a sterilization and disinfection light source.

The tunnel type ultraviolet sterilization machine uses continuous transmission of PTFE mesh belt to uniformly pass the material to be sterilized through the ultraviolet radiation tunnel without radiation dead corners, and ensures the sterilization effect through sufficient exposure time.

(3) Product features and technical advantages:

The tunnel type ultraviolet sterilization machine produced by Nanjing Feilong has the characteristics of no dead corners, good light irradiation conditions, thorough sterilization, low energy consumption, flexible and convenient installation, and adjustable speed and exposure time. The main material is adopted304Stainless steel, free from metal ion contamination issues. The tunnel walls are entirely made of stainless steel mirror panels, ensuring that ultraviolet rays are fully reflected inside the tunnel, with no blind spots for irradiation or sterilization.

The electrical devices and circuits are all located in the control cabinet or tunnel interlayer, with no exposed wires, safe and beautiful. The key ultraviolet lamp tube has a theoretical lifespan of up to9000Hour, choose international first-line brand Philips.

The product has a beautiful and elegant appearance, with a compact and reasonable structure. The left, right, and top protective plates are designed to be easy to disassemble, making maintenance and daily cleaning convenient.

Overall, UV disinfection technology has high efficiency and broad-spectrum sterilization, no secondary pollution. Tunnel type UV sterilizers have many advantages such as safe and reasonable design, safe and reliable operation, simple operation and maintenance, low cost, small footprint, low noise, continuous large-scale sterilization, and wide application fields.

(IV) Sterilization efficiency

UV disinfection technology has unparalleled sterilization efficiency compared to other technologies, with a sterilization rate of up to99%~99.9%.

The following table (Table)1）Listing the sterilization time of UV technology on several common bacteria and viruses generally only requires1Within seconds. Traditional chemical disinfection methods such as chlorine gas and ozone require reaching ultraviolet radiationUV-CThe bactericidal effect generally requires20Minutes to1Hours of time.
