The ionization process used in the facility consists of continuously conveying the products to be treated at a regulated speed through the E-beam radiation emitted by an electron accelerator.
E-beam treatment
The emitted electrons have a single energy level: 9.8 MeV +/- 0.2.
An automated conveyor system transports the products into the irradiation cell, then moves them under the electron beam at an appropriate speed (depending on the required dose and the nature of the product).
The treatment is generally carried out in two passes under the beam: one pass with the box upright, and a second pass with the box upside down (double-sided treatment).
The dose absorbed by the product mainly depends on the following factors:
- the power and energy of the electron beam,
- the speed at which it passes under the beam,
- the composition and density of the materials.
Electron beams are generated by electrical generators that use high-energy electrons (10 MeV), which are highly penetrating.
The treatment is carried out continuously; it is fast, with the exposure time to radiation lasting only a few seconds.
The dose, expressed in kiloGray (kGy), is inversely proportional to the speed of the conveyor under the electron beam.
The conveyor speed is the only control parameter required after prior validation of the packaging.
A safe and reproducible treatment.
Computer files, production document archiving, and the simplicity of the process ensure the reproducibility and safety of the treatments.
This is a physical process with no residual effects and no temperature increase.
