Abstract

In at least one illustrative embodiment, an electromagnetic filter may include a transfer pipe and multiple electromagnetic filter elements positioned in an interior volume of the pipe. Each electromagnetic filter element includes a support comb, a solenoid coupled to the support comb, and multiple magnetic members arranged in a planar array positioned within an opening of the support comb. Each magnetic member may rotate about an end that is coupled to the support comb. The magnetic members may be magnetostrictive sensors and may include a biorecognition element to bind with a target microorganism. A method for fluid filtration includes coupling the electromagnetic filter between a fluid source and a fluid destination, energizing the solenoids of each electromagnetic filter elements, and flowing a fluid media through the transfer pipe of the electromagnetic filter. The fluid media may be liquid food such as fruit juice. Other embodiments are described and claimed.

First claim

The invention claimed is:

1. An electromagnetic filter element comprising:
a support comb comprising a magnetic material, wherein the support comb defines an opening;
a solenoid coupled to the support comb and configured to, when energized, cause the support comb to generate a magnetic field; and
a plurality of elongated magnetic members arranged in a planar array positioned within the opening of the support comb, wherein each magnetic member comprises a first end and a second end, and wherein the first end of each magnetic member is coupled to the support comb at a corresponding pivot point, wherein each magnetic member is rotatable about the corresponding pivot point.

2. The electromagnetic filter element of claim 1 , wherein magnetization of the support comb is controlled by the solenoid, wherein each of the magnetic members is magnetically coupled to the support comb, and wherein each magnetic member may rotate about the first end of the magnetic member coupled to the support comb.

3. The electromagnetic filter element of claim 1 , wherein the first end of each magnetic member is hingedly attached to the support comb.

4. The electromagnetic filter element of claim 1 , wherein each magnetic member comprises a magnetostrictive sensor comprising magnetostrictive material.

5. The electromagnetic filter element of claim 4 , wherein each magnetostrictive sensor further comprises a biorecognition element to bind with a microorganism.

6. The electromagnetic filter element of claim 5 , wherein the biorecognition element comprises a bacteriophage that is genetically engineered to bind with the microorganism.

7. An electromagnetic filter comprising:
a transfer pipe that defines an interior volume; and
a plurality of electromagnetic filter elements positioned in the interior volume of the transfer pipe, wherein each of the electromagnetic filter elements comprises:
a support comb comprising a magnetic material, wherein the support comb defines an opening, wherein the opening describes a cross-section of the interior volume of the transfer pipe;
a solenoid coupled to the support comb and configured to, when energized, cause the support comb to generate a magnetic field; and
a plurality of elongated magnetic members arranged in a planar array positioned within the opening of the support comb, wherein each magnetic member comprises a first end and a second end, and wherein the first end of each magnetic member is coupled to the support comb at a corresponding pivot point, wherein each magnetic member is rotatable about the corresponding pivot point.

8. The electromagnetic filter of claim 7 , wherein each of the electromagnetic filter elements has a different orientation of the plurality of magnetic members.

9. The electromagnetic filter of claim 7 , wherein magnetization of each support comb is controlled by the corresponding solenoid, wherein each of the magnetic members is magnetically coupled to the corresponding support comb, and wherein each magnetic member may rotate about the first end of the magnetic member coupled to the corresponding support comb.

10. The electromagnetic filter of claim 7 , wherein each magnetic member comprises a magnetostrictive sensor comprising magnetostrictive material.

11. The electromagnetic filter of claim 10 , wherein each magnetostrictive sensor further comprises a biorecognition element to bind with a microorganism.
