ABSTRACT:
Microorganisms are killed in a food product using an electrode placed into electrical contact with the food product, a charge supply circuit, a switch that selectively couples the charge supply circuit to the electrode, and a controller. The switch first configures the charge supply circuit so as to deliver a charge to the electrode when the switch assumes a first state, and next configures the charge supply circuit so as to absorb the charge from the electrode when the switch assumes a second state. As a result, a net charge delivered to the electrode is substantially zero. The controller controls the switch to sequentially assume the first and second states. The delivery of the zero net charge prevents the fouling of the electrode.
