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.

Bulk material irradiation system and method

An irradiation system includes a conveying system for moving material to be irradiated through a processing area. An irradiation source applies radiation to material in the processing area. The conveying system is enclosed by a sealed conduit in at least the processing area, providing the capability to control the atmosphere inside the sealed conduit and to clean the interior of the sealed conduit according to industrial sanitation methods.

Irradiation system and method

An irradiation system includes a radiation source providing radiation in a localized radiation exposure area and a shielding structure around the radiation source. A conveyance system transports product into the shielding structure, through the radiation exposure region and out of the shielding structure. The conveyance system includes an input portion for carrying the product into the shielding structure at a first elevation. A first elevator moves the product from the first elevation to a second elevation different from the first elevation. A processing portion of the conveyance system carries the product at the second elevation through the radiation exposure region. A second elevator moves the product from the second elevation to a third elevation different from the second elevation. An output portion of the conveyance system carries the product out of the shielding structure at the third elevation.
