Abstract

A method for rapid sterilization, comprising: a to be sterilized utensil (3) and / or object is placed into a sterilizing apparatus, where a 200-280 nanometer ultraviolet light source (2) and a support mechanism (4) are provided within the sterilizing apparatus, the to be sterilized utensil (3) and / or the support mechanism (4) are made of a material transmitting ultraviolet rays of 200-280 nm, the ultraviolet transmittance of the material transmitting ultraviolet rays of 200-280 nm is ≥ 60% at a thickness of 1 mm; the ultraviolet light source (2) illuminates the to be sterilized utensil and / or object from at least two directions, where the ultraviolet light source (2) is an ultraviolet lamp or an ultraviolet LED, the radiated power of the ultraviolet light source (2) is ≥ 20 mW / cm2, the ultraviolet conversion efficiency is ≥ 30%. Also disclosed is the sterilizing apparatus for use in the method for rapid sterilization.

Description

technical field [0001] The invention relates to the technical field of disinfection, in particular to a rapid disinfection method and device. Background technique [0002] Existing disinfection methods include electric heating disinfection, infrared disinfection and ultraviolet disinfection. Among them, heating disinfection or infrared heating disinfection needs to go through heating-heating-cooling, and the whole cycle is as long as 2-3h. Moreover, the disinfection temperature of heating disinfection or infrared heating disinfection is about 120°C, which cannot kill high-temperature-resistant microorganisms, and the disinfection is not complete. . [0003] And ultraviolet disinfection is universal, can kill all kinds of microorganisms including spores, and can kill and remove many algae, and ultraviolet disinfection has high efficiency and fast speed, which is better than conventional heating and infrared disinfection. Disinfection cabinets on the market claim to be able ...
