Abstract

An anti-oxidation food preparation device includes a food preparation vessel having an electrically conductive body and a separate power supplying base. The base generates high frequency AC power that is transferred by a primary coil to as secondary coil maintained by the vessel. A rectification circuit converts the high frequency AC power into a rippled, rectified AC current that is supplied to the electrically conductive body of the vessel so as to create a reducing environment of available electrons for absorption by the food as it is prepared.

Claims

1. A food preparation device for comprising:

a base maintaining a power source configured to generate a first power signal;

a food preparation vessel to prepare food, said vessel maintaining a rectification circuit configured to receive a second power signal induced by said first power signal; and

a rectification circuit maintained by said vessel and electrically coupled 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 so as to create a reducing environment of available electrons for absorption by the food carried by the vessel.

2. The food preparation device of claim 1, wherein said first power signal comprises a square wave.

3. The food preparation device of claim 1, wherein said rectification circuit comprises:

a coil;

a schotky diode arranged in series with one end said coil; and

a capacitor arranged in parallel with said coil and said diode, such that the cathode of said diode is coupled to said capacitor to form a first node, and the coupling of said coil with said capacitor forms a second node.

4. The food preparation device of claim 4, further comprising a current regulator coupled to the output of said parallely arranged capacitor to control the magnitude of said current delivered to said vessel.

5. The food preparation device of claim 4, further comprising a first connection point coupled to the output of said current regulator, and a second connection point coupled to said second node, wherein said first and second connection points are electrically coupled to said vessel.

6. A method of preparing food comprising:

providing an electrically conductive vessel to prepare food, said vessel including a rectification circuit having a first and a second connection point electrically coupled to said vessel;

said rectification circuit transforming a high frequency AC signal into a rippled, rectified AC current; and

supplying said rippled, rectified AC current between said first and second connection points so as to create a reducing environment of available electrons for absorption by the food.

7. The method of claim 6, further comprising:

controlling the magnitude of said rippled, rectified AC current coupled to said first connection point to a create a reducing environment with a desired level of available electrons for absorption by the food at said supplying step.

8. A food preparation device for use with an inductive heating appliance comprising:

a vessel for preparing food, said vessel having a conductive body, wherein said receiving surface maintains a non-conductive coating disposed thereupon;

a rectification circuit electrically coupled to said body;

a first wire section embedded within said coating, said first wire section having each end coupled to said rectification circuit;

a second wire section embedded within said coating, said second wire section coupled at one end to said first wire section and at the other end to said rectification circuit;

wherein said rectification circuit converts the electrical current induced at the first wire section by the inductive heating appliance into a rippled, rectified AC current that is supplied to said conductive body by said rectification circuit, so as to create a reducing environment of available electrons for absorption by the food carried by said vessel.

9. The food preparation system of claim 8, wherein said rectification circuit is integral with said body.

10. The food preparation system of claim 8, wherein said first wire section substantially forms a loop.

11. The food preparation system of claim 8, wherein said rectification circuit comprises:

a bridge rectifier coupled to each end of said first wire section;

a voltage regulator coupled to the output of the bridge rectifier, and to said second wire section; and

a current regulator coupled to the output of the voltage regulator;

wherein said current regulator supplies said rippled, rectified AC current to said electrically conductive body.

12. The food preparation system of claim 8, further comprising:

a capacitor coupled to said voltage regulator to store energy when said vessel does not receive power from the inductive heating appliance.
