Abstract
A bulk material irradiation system includes an input for inserting bulk material. A bulk material tube is connected to the input, forming a path for bulk material flow. A pressurizing assembly is connected to the bulk material tube for forcing the bulk material to flow through the bulk material tube. An irradiation assembly provides ionizing radiation to irradiate the bulk material passing adjacent to the irradiation assembly in the bulk material tube. Irradiated bulk material exits the bulk material tube through an output.
Claims9
A bulk material irradiation system comprising:
- an input for inserting bulk material;
- a plurality of bulk material tubes each offset from adjacent tubes in an alternating pattern, connected to the input and forming paths for bulk material flow;
- a pumping assembly connected to the bulk material tubes for forcing the bulk material to advance through the bulk material tubes;
- an irradiation assembly providing ionizing radiation that penetrates a full thickness of the bulk material in the plurality of offset bulk material tubes to irradiate the bulk material passing adjacent to the irradiation assembly in the bulk material tubes;
- and
- an output for irradiated bulk material to exit the bulk material tubes.
A bulk material irradiation system comprising:
- an input for inserting bulk material;
- a bulk material tube connected to the input and forming a path for bulk material flow, wherein the bulk material tube is elliptical in shape and has a wall with a thickness that is thicker around edge portions of the bulk material tube than around a central portion of the bulk material tube;
- a pumping assembly connected to the bulk material tube for forcing the bulk material to advance through the bulk material tube;
- an irradiation assembly providing ionizing radiation that penetrates a full thickness of the bulk material to irradiate the bulk material passing adjacent to the irradiation assembly in the bulk material tube;
- and
- an output for irradiated bulk material to exit the bulk material tube.
A bulk material irradiation system comprising:
- an input for inserting bulk material;
- a bulk material tube connected to the input and forming a path for bulk material flow, wherein the bulk material tube has an outer wall that is rectangular in shape and an inner wall that is elliptical in shape, a region between the outer wall and the inner wall including a liquid with an irradiation absorption characteristic that approximately matches an irradiation absorption characteristic of the bulk material in the bulk material tube;
- a pumping assembly connected to the bulk material tube for forcing the bulk material to advance through the bulk material tube;
- an irradiation assembly providing ionizing radiation that penetrates a full thickness of the bulk material to irradiate the bulk material passing adjacent to the irradiation assembly in the bulk material tube;
- and
- an output for irradiated bulk material to exit the bulk material tube.
