Patent ID: 8076620

Claim:
A food preparation device for comprising: a base maintaining a power source configured to generate a first power signal; an electrically conductive food preparation vessel to prepare food; and a rectification circuit maintained by said vessel and electrically coupled to said vessel, said rectification circuit comprising: a coil configured to receive a second power signal induced by said first power signal; a schottky diode arranged in series with one end said coil; a capacitor arranged in parallel with said coil and said diode, such that the cathode of said diode is coupled to one end of said capacitor, and said coil is coupled to another end of said capacitor to form a first connection point that is electrically coupled to said vessel; and a current regulator coupled to said capacitor, said current regulator having an output that forms a second connection point that is electrically coupled to said vessel and spaced apart from said first connection point, said current regulator configured to control the magnitude of said current delivered to said vessel; wherein when said rectification circuit receives said second power signal, said rectification circuit generates a rippled, rectified AC current signal from said second power signal, and supplies it to said vessel at said second connection point, so as to create a reducing environment of available electrons for absorption by the food carried by the vessel.
