Method for processing materials
Systems and methods for thermal preservation (sterilization) of heterogeneous and multiphase foods and biomaterials in order to achieve their shelf stability at ambient level temperatures. Flowing heterogeneous, 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.
1. A method comprising:
providing an electromagnetic system comprising:
a first applicator comprising a entry end to receive electromagnetic energy, a termination end, a waveguide, a material entry port, and a material exit port; and
a second applicator comprising a beginning portion, an end portion, a waveguide, a material entry port, and a material exit port, wherein a first termination member is attached to the termination end 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; and
at least one electromagnetic generator that is configured to provide electromagnetic energy to the first and second applicators;
continuously pumping heterogeneous materials through the first and second applicators so that the heterogeneous materials traveling through and exiting the first applicator is then delivered through the second applicator and so that the heterogeneous materials absorb electromagnetic energy from the first applicator and absorb electromagnetic energy from the second applicator; and
delivering electromagnetic energy from at least one electromagnetic generator to the first and second applicators while the heterogeneous materials are being pumped.
2. The method of claim 1 , wherein the first termination member comprises an absorption load which absorbs the electromagnetic energy not absorbed into the heterogeneous materials.
3. The method of claim 2 , wherein the absorption load comprises a water load.
4. The method of claim 1 , wherein the first termination member comprises a conductive member which reflects the electromagnetic energy not absorbed into the heterogeneous materials.
5. The method of claim 1 , wherein the pumping heterogeneous materials comprises
pumping the heterogeneous materials in a conduit which enters the first applicator at the first applicator material entry port and exits the first applicator at the first applicator material exit port; and
pumping the heterogeneous materials so that the heterogeneous materials that exits the first applicator at the first applicator material exit port enters the second applicator at the second applicator material entry port and exits the second applicator at the first applicator material exit port.
6. The method of claim 5 , wherein the first applicator material exit port is located proximate to the first termination member of the first applicator.
7. The method of claim 1 , wherein the pumping heterogeneous materials comprises pumping the heterogeneous materials in a conduit along a plane that is substantially along the longitudinal axis of the first applicator.
8. The method of claim 7 , wherein the pumping heterogeneous materials comprises pumping the heterogeneous materials at an incline so that the heterogeneous materials are pumped against the force of gravity.
9. The method of claim 1 , wherein the delivering the electromagnetic energy comprises delivering the electromagnetic energy from a first electromagnetic generator to the first applicator while the heterogeneous materials are being pumped into the first applicator and from a second electromagnetic generator to the second applicator while the heterogeneous materials are being pumped into the second applicator.
10. The method of claim 1 wherein the at least one generator comprises a generator that provides electromagnetic power to both the first and second applicators.
11. The method of claim 1 , wherein the width, height and depth of particles of the solid materials of the heterogeneous materials is at least one millimeter.
