Abstract
Bulk material solids are packaged in a shaped block and the packaged block is irradiated on two sides using high-energy electron beam radiation to uniformly irradiate the solids in the package.
Claims26
A method of electron beam processing bulk material solids comprising
- packing bulk materials solids in a container having first and second opposed sides which define an internal container zone for irradiating the bulk material solids,
- forming a layer of the bulk material solids at a predetermined, substantially uniform solid thickness in the internal container zone,
- sealing the container to provide a controlled internal atmosphere within the internal container zone and with said sides in direct contact with the bulk material solids layer to form a block of bulk material solids,
- passing the container through an electron beam radiation zone,
- exposing each of the first and second sides of the container to a dose of electron-beam radiation which passes through each respective container side for uniformly irradiating the bulk materials solids.

A method of electron beam processing bulk polymeric material solids comprising
- packing bulk polymeric materials solids in a generally rectangular plastic film container having first and second opposed sides which define an internal container zone for irradiating the bulk polymeric material solids,
- forming a layer of the bulk polymeric material solids at a predetermined substantially uniform solid thickness in the internal container zone,
- sealing the container to provide a controlled internal atmosphere within the internal container zone and with said sides in direct contact with the bulk polymeric material solids layer to form a rectangular block of bulk polymeric material solids,
- passing the container through an electron beam radiation zone with said bulk polymeric material solids thickness substantially perpendicular to the direction of the electron beam,
- exposing each of the first and second sides of the container to a dose of electron beam radiation which passes through each respective container side for uniformly irradiating the bulk materials solids.
