In addition, hydrogen peroxide shows a high disinfection power of 10 to 6 logs when compared with conventional chlorine disinfectants, ozone gas, and plasma disinfecting power. The existing sterilization apparatus using hydrogen peroxide has a steam method and pressure to be heated. It uses a method of discharging small particles by use of it. However, in the case of the heated steam method, since the concentration of hydrogen peroxide is high, some methods are used to reduce the concentration. Therefore, the price of the equipment is very expensive and the pressure is limited. In the case of the formula, if it does not have a certain size at a high pressure, dew condensation occurs severely, and it has a disadvantage of wetting disinfectant (medical device). have.

Because of this, there is a need for a sterilizing sterilizer which is inexpensive, easily handled and has a fast disinfection time using environmentally friendly hydrogen peroxide.
