Abstract

A crop treatment apparatus is capable of irradiating plant products harvested from beneath the surface of the ground to prevent sprouting, regrowth, and/or decay of the plant products and/or contamination of the plant products by one or more microorganisms. The crop treatment apparatus may include shielding and a conveyor system. The conveyor system may direct the plant products past an irradiation element and then directly into storage or packaging. Embodiments of crop treatment apparatuses that are capable of treating plant products as they are harvested or prior to harvesting the plant products from the ground are also disclosed.

Claims

1. A method for inhibiting the sprouting of a plant product, comprising:

introducing the plant product onto a conveyor system;

conveying the plant product into shielding;

conveying the plant product over a nonlinear path through the shielding, including conveying the plant product past ionizing radiation within the shielding to expose the plant product to the ionizing radiation within the shielding;

while conveying the plant product past the ionizing radiation, causing the plant product to tumble or roll; and

conveying the plant product out of the shielding, directly into packaging or storage.

2. The method of claim 1, further comprising:

temporarily setting up the conveyor system, the shielding, and a source of the ionizing radiation at a packaging location or a storage location.

3. The method of claim 2, further comprising:

disassembling the shielding, the conveyor system, and the source of the ionizing radiation for transportation to another location.

4. The method of claim 1, wherein conveying the plant product past the ionizing radiation comprises limiting exposure of the plant product to the ionizing radiation to an amount that will inhibit sprouting and/or growth of the plant product without damaging the food product.

5. The method of claim 1, further comprising:

conveying the plant product through sanitizing radiation while causing the plant product to tumble or roll.

6. The method of claim 5, wherein conveying the plant product through the sanitizing radiation comprises killing microorganisms on the plant product.

7. The method of claim 1, wherein conveying the plant product past ionizing radiation comprises inhibiting cell division in meristematic cells of the plant product.

8. A crop treatment apparatus, comprising:

shielding including a first side with an entry, a second side with an outlet, an a non-linear path between the entry and the outlet;

a conveyor system including an entry portion, an entry bend, a widening portion, a treatment portion, a narrowing portion, an outlet bend, and an outlet portion positioned along the non-linear path; and

at least one irradiation element capable of generating radiation and directing the radiation over a field of exposure coincident with at least a portion of the treatment portion of the conveyor system.

9. The crop treatment apparatus of claim 8, further comprising:

a flexible barrier located over the entry in the first side of the shielding.

10. The crop treatment apparatus of claim 8, wherein the widening portion of the conveyor system includes adjustable side rails.

11. The crop treatment apparatus of claim 8, wherein the at least one radiation element comprises an electron accelerator.

12. The crop treatment apparatus of claim 11, wherein the treatment portion of the conveyor system includes a residency element that controls an amount of time a food product is exposed to ionizing radiation generated and delivered by the at least one irradiation element.

13. The crop treatment apparatus of claim 11, wherein the at least one radiation element further comprises a source of sanitizing radiation.

14. The crop treatment apparatus of claim 13, wherein the source of sanitizing radiation generates and delivers ultraviolet C radiation and/or HINS light.

15. The crop treatment apparatus of claim 8, wherein the at least one radiation element comprises a source of sanitizing radiation.

16. A mobile irradiating apparatus, comprising:

a transport component capable of enabling transportation of the mobile irradiating apparatus over a surface of the ground; and

a source of ionizing radiation carried by the transport component and capable of directing ionizing radiation into the ground beneath the transport component during transportation of the mobile irradiating apparatus over the surface of the ground in a manner capable of preventing growth and/or replication of meristematic cells of plant products beneath the surface of the ground without substantially preventing growth and/or replication of non-meristematic cells of the plant products beneath the surface of the ground.

17. The mobile irradiating apparatus of claim 16, wherein the source of ionizing radiation comprises an electron accelerator.

18. The mobile irradiating apparatus of claim 16, wherein the electron accelerator is capable of directing a dose of about 3 kilorads to about 10 kilorads to the ground at a rate of at least about 10⁶ rads per second.
