Abstract
A plasma sterilization apparatus includes a voltage-applying unit that applies a voltage to a sterilization target having conductivity; a pair of electrodes that apply, in a discharged state, the voltage applied by the voltage-applying unit to the sterilization target via a dielectric; and a position changing unit that changes a relative position between the pair of electrodes and the sterilization target.
Claims7
A plasma sterilization apparatus configured to apply a voltage to an agricultural product as a sterilization target having conductivity comprising:
- a power source;
- multiple pairs of electrodes, each electrode having the same shape respectively, that apply, between one electrode and another electrode of each pair, in a discharged state, said voltage, supplied from said power source, to said sterilization target via a dielectric and wherein each of the electrodes is flexible and comprises a conductor covered with said dielectric;
- and
- a position changing unit configured to change a relative position between said pairs of electrodes and said sterilization target.
