Number), and the residual of disinfectant is less than 1ppm, reaches safety range.
Eye-drop liquid bottle sterile biological indicator testing result in table 1. vacuum tank and case
To sum up, the present invention has the advantage that
1., because the boiling point of solution under vacuum reduces, disinfectant is easier to volatilize, therefore right under vacuum
Disinfectant is sprayed, and compared with being easier under condition of normal pressure to obtain separating drying, so drastically increases atomizing effect and drying
Efficiency, atomization particle is also less, even up to nanoscale.And the atomization particle more little time suspending in atmosphere is longer, just
The antibacterial of same in the air of more having an opportunity is fully contacted and reaches the purpose of sterilizing.
2. the nanometer mist disinfectant injection sterilizing casing 3 due to being formed after spraying by the way of pulsation spraying, not only
Improve the concentration of nanometer mist disinfectant in sterilizing casing 3, but also easily nanometer mist disinfectant is injected into various
In small pipeline (as medical various endoscopies, disposable syringe etc.) and small containers (as eye-drop liquid bottle), therefore this low
Warm impulse sterilization mode, is particularly well-suited to various small-sized salable spaces (as freeze dryer) and each of the interior placement of casing 3 that sterilize
The sterilization of the object (as plastic catheter and plastic containers) of class non-refractory.
3. because the disinfectant of residual in the casing 3 that sterilizes is purged by the mode employing vacuum impulse simultaneously, not only
Reduce manufacturing cost and the use cost of equipment, and the disinfectant of residual is removed very thorough, save sterilization and make
The time of industry.
4. it is different from vaporized hydrogen peroxide sterilization technology (vhp, vaporized hydrogenperoxide), vhp needs
Using the change hydrogenperoxide steam generator (more than more than 30%) of high concentration, not only corrosivity are strong, and dense with change hydrogen peroxide
Degree increases, and viscosity is also gradually increased, and is also not easy in atmosphere to spread.And this technology only need to use less than 5% change peroxidating
Hydrogen solution it is not required that hot conditionss, using safer.
5. the present invention is equipped with detecting system 7, can at any time the concentration of disinfectant nanometer mist be monitored it is also possible to right
After elimination, the concentration of residual disinfectant nanometer mist is detected.
6. the active Hydrogen Peroxide Disinfectant of present invention cooperation uses, and has noresidue, free of contamination advantage after sterilizing, is one
Plant the Sterilization and Disinfection Equipment of environmental protection.
The above, be only 1 embodiment of the application, and not the application is done with any type of restriction although this Shen
Please with preferred embodiment disclose as above, but and be not used to limit the application, any those skilled in the art, do not taking off
