Abstract

Systems and method for thermal preservation (sterilization) of heterogenous and multiphase foods and biomaterials in order to achieve their shelf stability at ambient level temperatures. Flowing heterogenous, multiphase foods and biomaterials are exposed to single or multiple stages of electromagnetic energy under continuous flow conditions within conduits passing through the electromagnetic energy exposure chambers.

Claims (40)

1. A system comprising:

a conduit configured to carry heterogeneous materials that is pumped therethrough;

a first applicator comprising an end portion, a waveguide, a material entry port, and a material exit port, wherein a terminating member is connected to the first applicator, and wherein the heterogeneous materials are pumped along a longitudinal length of the waveguide into the material entry port of the end portion of the first applicator and out the material exit port while electromagnetic energy is delivered to the first applicator;

an electromagnetic generator connected to the first applicator so as to provide the electromagnetic energy to the first applicator while the heterogeneous materials are being conveyed horizontally along a longitudinal axis of the waveguide;

a second applicator comprising a beginning portion, an end portion, and a second waveguide, wherein electromagnetic energy is conveyed from the beginning portion through the second waveguide to the end portion;

wherein the first applicator further comprises an electromagnetic energy entry port and an electromagnetic energy exit port,

wherein the second applicator further comprises an electromagnetic energy entry port and an electromagnetic energy exit port,

wherein the first applicator material entry port is located proximate to the first applicator electromagnetic energy entry port,

wherein the first applicator material exit port is located proximate to the first applicator electromagnetic energy exit port,

wherein the second applicator material entry port is located proximate to the second applicator electromagnetic energy entry port, and

wherein the second applicator material exit port is located proximate to the second applicator electromagnetic energy exit port.

2. The system of claim 1 , wherein at least one percent (1%) of the heterogeneous materials comprises solid materials.

3. The system of claim 1 , wherein the heterogeneous materials comprise at least one of fruits, vegetables or a material originating from an animal.

4. The system of claim 1 , wherein the electromagnetic generator is the only generator supplying electromagnetic energy to the first and second applicators.

5. The system of claim 1 , wherein a first termination member is attached to the end portion of the first applicator so that no electromagnetic energy transfers from the first applicator to the second applicator, and wherein a second termination member is attached to the end portion of the second applicator so that electromagnetic energy does not proceed past the second termination member.

6. The system of claim 5 , wherein a first termination member is attached to the end portion of the first applicator so that no electromagnetic energy transfers from the first applicator to the second applicator, and wherein a second termination member is attached to the end portion of the second applicator so that electromagnetic energy does not proceed past the second termination member.

7. The system of claim 5 , wherein the heterogeneous materials comprises a carrier fluid, dense particles having a density higher than the carrier fluid, neutral particles having a density proximate to the carrier fluid, and buoyant particles having a density lower than the carrier fluid, wherein the dense particles are heated faster in the conduit by the electromagnetic energy than the neutral or buoyant particles because the dense particles initially are more concentrated in the bottom portion of the conduit's interior.

8. The system of claim 1 , wherein the conduit comprises an interior and is attached to the first applicator; and

wherein the conduit interior comprises a top portion, a bottom portion and a center portion, wherein the conduit is aligned along the longitudinal length of the first applicator so that a higher concentration of the electromagnetic energy is applied to the bottom portion relative to the center and top portions of the conduit's interior thereby causing materials in the bottom portion of the conduit's interior to heat faster than materials in the center and top portions of the conduit's interior.

9. The system of claim 8 , wherein the conduit is positioned along a plane that is substantially perpendicular to the force of gravity.

10. The system of claim 8 , wherein the conduit is positioned along a plane that is at an angle of at least one degree relative to the ground so that the first applicator material entry port is lower than the first applicator material exit port, thereby forcing the material to be pumped against the force of gravity.

11. A system comprising:

a conduit configured to carry heterogeneous materials that is pumped therethrough;

a first applicator comprising an end portion, a waveguide, a material entry port, and a material exit port, wherein a terminating member is connected to the first applicator, and wherein the heterogeneous materials are pumped along a longitudinal length of the waveguide into the material entry port of the end portion of the first applicator and out the material exit port while electromagnetic energy is delivered to the first applicator;

an electromagnetic generator connected to the first applicator so as to provide the electromagnetic energy to the first applicator while the heterogeneous materials are being conveyed horizontally along a longitudinal axis of the waveguide;

a second applicator comprising a beginning portion, an end portion, and a second waveguide, wherein electromagnetic energy is conveyed from the beginning portion through the second waveguide to the end portion;

wherein the first applicator further comprises an electromagnetic energy entry port and an electromagnetic energy exit port,

wherein the second applicator further comprises an electromagnetic energy entry port and an electromagnetic energy exit port,

wherein the first applicator material entry port is located proximate to the first applicator electromagnetic energy entry port,

wherein the first applicator material exit port is located proximate to the first applicator electromagnetic energy exit port,

wherein the second applicator material entry port is located proximate to the second applicator electromagnetic energy entry port,

wherein the second applicator material exit port is located proximate to the second applicator electromagnetic energy exit port,

wherein the electromagnetic generator is the only generator supplying electromagnetic energy to the first and second applicators,

wherein a first termination member is attached to the end portion of the first applicator so that no electromagnetic energy transfers from the first applicator to the second applicator, and wherein a second termination member is attached to the end portion of the second applicator so that electromagnetic energy does not proceed past the second termination member,

wherein the conduit comprises an interior and is attached to the first applicator, and

wherein the conduit interior comprises a top portion, a bottom portion and a center portion, wherein the conduit is aligned along the longitudinal length of the first applicator so that a higher concentration of the electromagnetic energy is applied to the bottom portion relative to the center and top portions of the conduit's interior thereby causing materials in the bottom portion of the conduit's interior to heat faster than materials in the center and top portions of the conduit's interior.

12. The system of claim 11 , wherein the heterogeneous materials comprises a carrier fluid, dense particles having a density higher than the carrier fluid, neutral particles having a density proximate to the carrier fluid, and buoyant particles having a density lower than the carrier fluid, wherein the dense particles are heated faster in the conduit by the electromagnetic energy than the neutral or buoyant particles because the dense particles initially are more concentrated in the bottom portion of the conduit's interior.

13. The system of claim 11 , wherein the conduit is positioned along a plane that is substantially perpendicular to the force of gravity.

14. The system of claim 11 , wherein the conduit is positioned along a plane that is at an angle of at least one degree relative to the ground so that the first applicator material entry port is lower than the first applicator material exit port, thereby forcing the material to be pumped against the force of gravity.

15. The system of claim 11 , wherein the conduit is positioned along a plane that is at an angle of at least one degree relative to the ground so that the first applicator material entry port is lower than the first applicator material exit port, thereby forcing the material to be pumped against the force of gravity.
