AI Technical Summary

Technical Problem

In existing VHP sterilization technology, free radicals are prone to decay during transport, resulting in unstable sterilization effects, low efficiency, and difficulty in adapting to complex structures or demanding environments.

Method used

An ionization device is installed inside the sterilization chamber to ionize hydrogen peroxide in dry fog state, increasing the concentration of free radicals. A stable sterilization gas path is formed through a particle size screening module and a circulating fan. Gas exchange is carried out in conjunction with a temperature sensor and a fan to ensure the stability of the free radical concentration.

Benefits of technology

It improves the stability and efficiency of sterilization, adapts to complex structures and demanding environments, and enhances sterilization uniformity and safety.
