<p>There is provided a low temperature plasma sterilization system comprising a reaction chamber (1) for receiving an item (9) to be sterilized, said item being wrapped in a packaging material (10); an anode (2) and a cathode (3) disposed above and below the item (9) to be sterilized in the reaction chamber (1) respectively; an injection heater (5) connected to said anode (2) via a mass flow controller (4); a plasma power source (8) connected to said cathode (3) via an impedance matching circuit (6) and an impedance matching controller (7) for generating high-frequency power; and a vacuum pump (11) disposed at the lower part of said reaction chamber (1), wherein a hydrogen peroxide solution (12) in the liquid phase is turned into gaseous hydrogen peroxide by means of said injection heater (5) prior to the sterilization with plasma, and then the gaseous hydrogen peroxide is adjusted and injected at desired pressure by means of said mass flow controller (4), to accomplish the pre-treatment.</p> |
