Introduction of Sterilization
Technology:
1. Adopting high-energy broadband pulsed
xenon light (with a spectral range of 190nm-1200nm), its spectral energy is
hundreds of times that of traditional ultraviolet light, instantly producing
extremely high-energy visible light, ultraviolet, and multiple electromagnetic
wave aggregation effects
2. High sterilization efficiency,
capable of achieving a sterilization effect of over 99.999%
3. Low energy consumption, saving 80%
-90% energy compared to traditional ultraviolet lamps
4. The module design is flexible and
can adapt to different equipment production lines
5. Cold sterilization technology,
especially suitable for sterilizing temperature sensitive items
6. Flexible control, start and stop
immediately
7. No use of chemical reagents, no
pollution or residue
Principles
Pulse light sterilization technology is
a technique that uses strong white light flashing to sterilize. The generation
of pulsed light requires two devices to complete:
(1) A release system for energy storage
with power amplification function, which accumulates electrical energy for a
relatively long time (a fraction of a second) and then releases it to do work
in a short time (a millionth or a thousandth of a second), thus amplifying
power. The result is that within the working cycle, only the average energy is
consumed to obtain a relatively high peak energy, achieving instant
sterilization.
(2) The photoelectric conversion system
stores the generated pulse energy in an inert gas lamp and produces
high-intensity instantaneous pulse light through ionization. The wavelength of
pulsed light ranges from the ultraviolet region to the near-infrared region,
with ultraviolet being the main band responsible for sterilization, while other
bands have a certain synergistic effect.
