example 1

[0019] Will contain a concentration of 5mg / m 3 The ethyl acetate enters the organic substance filling chamber through the inlet, turns on the flow rate switch, sprays a small amount of spray to the plastic container through the nozzle, sprays for 2 minutes, and the pulley will drive the plastic packaging container to slide to the right, so that it is placed in the nitrogen oxide filling chamber Next, spray nitrogen oxides through the nozzle to make it enter the plastic packaging container. After spraying for 4 minutes, it will slide to the disinfectant filling chamber for 3 minutes of disinfection spraying. After the three spraying processes are completed, the plastic packaging container will rest on the pulley. Set it aside for 2 minutes to allow it to fully react. After the reaction, use a blower to blow dry. At the same time, the residual nitrogen oxide gas in the plastic packaging container is sucked into the recovery device to reduce nitrogen substances and generate nitrog...

Abstract

The invention discloses a method and a device for disinfecting and sterilizing plastic packaging containers. According to the invention, the disinfecting and sterilizing purpose is achieved by performing photochemical reaction by virtue of sequentially adding 5-10mg / m<3> ethyl acetate, a nitrogen oxide composed of nitrous oxide, nitrogen tetroxide and nitrogen dioxide, 0.1-0.3% of ferrous and 35-45% of hydrogen peroxide to generate radical ions which have a strong oxidation property. The method and the device disclosed by the invention have the beneficial effects that the plastic packaging containers are disinfected and sterilized by generating the radical ions, without secondary pollution and plastic deformation, thus avoiding ageing due to the action of ultraviolet ray and prolonging the service life and time; the plastic packaging containers after being disinfected and sterilized by the radicals are free from water stain residue and good in effect.

Description

technical field [0001] The invention relates to a method and device for sterilizing plastic packaging containers, in particular to a method for sterilizing plastic packaging containers. Background technique [0002] At present, there are many ways to sterilize packaging containers. Among them, the moist heat sterilization method increases the steam temperature by pressurization, and uses high-pressure steam to sterilize, which has strong penetrating power and high temperature, and the sterilization effect is the best. However, it is not suitable for plastic packaging containers. Under high temperature and high pressure, plastic packaging containers will be deformed and their service life will be reduced. Although ultraviolet disinfection does not cause the above problems, its penetrating power is weak, there are many influencing factors, and the bactericidal efficacy is limited to a certain extent. And generally, if the UV lamp is used for more than 100 hours, it should be ...
