This invention relates to a processing machine of the food industry, specifically, a new electronic sterilization device for liquid beverage or liquids. One pole of the electric voltage device is connected to the voltage connector sleeve with an outlet of hollow capillary emitter, and the other pole of the electric voltage device is connected to the collection container. The inner diameter of the exit end of the hollow capillary emitter is very small. Liquid forms a Taylor cone at the exit end under the electric field force, thus a high electric field area is formed on the surface of the Taylor cone. Bacteria passing through the high electric field area will be fully polarized, thoroughly disrupted or electroporated, and finally killed. This invention features simple structure and easy operation with better and more thorough sterilization effect, showing distinct technical advantages especially for substances inappropriate to be treated in high temperature, high pressure or strong electric field, and its wide use in food and beverage industry can be expected in the very near future.
