The sterilizing system consists of a high-voltage pulse generating power supply, and a sterilizing chamber. In the power supply section, the input electric power is converted into low current high voltage power that is then used to charge a capacitor. The power is then discharged in an instant across a spark gap. The plused discharge is repeated 100 times per second, efficiently sterilizing the brown rice in the sterilizing chamber. The targets of this sterilizing process are microoganisms that live on the surface of the brown rice. This method has been confirmed to be 99% effective at killing Bacterial number and Eumycetes.
