X-ray inspection systems provide reliable contamination detection within products in a wide range of retail packaging.
How to Choose the Right X-ray System
This White Paper offers manufacturers practical guidance on how to select the most appropriate x-ray machine and reject system for a specific application. It also advises on production line integration, especially where product handling may be difficult, and the incorporation of failsafe design features, which will satisfy most brand, retailer and food-industry requirements.
Choosing the right system is crucial to the success of an x-ray inspection program. X-ray equipment cannot solve contamination or production problems unless each element of the system, from beam angle to reject mechanism, has been chosen to fit the line and the product. In addition to helping manufacturers specify a system for optimal inspection, a good grasp of x-ray technology will help to ensure smooth installation, avoid major modifications after integration, maximize operational efficiency and ease verification testing.
The white paper focuses on the following areas in detail:
- What are the differences between vertical beam, horizontal beam and combination beam x-ray systems?
- What transport system designs are available?
- What reject systems are available and which factors determine the correct choice?
- What reject receptacles are available?
- How to prevent typical reject problems?
- How can integrated failsafe design features mitigate the risks associated with system malfunction?

The weakest link in most x-ray systems is ineffective reject systems, which result in contaminated product not being effectively and reliably removed from the production line. A correctly-specified x-ray system should be foolproof and capable of rejecting all suspect packs under all circumstances, regardless of the frequency of occurrence or the location of the foreign body within the product.
When specifying an x-ray inspection system, the following application problems should be considered:
- Reject not suitable for the application
- System not capable of removing consecutive contaminated packs
- Failure of the reject due to low air pressure/volume, pipe blockage or solenoid failure
- Downstream product backing up to and through the x-ray system
- Conveyor speed changed without changing reject timings
- Product spacing/pitching and reject not compatible
One of the benefits of a single source of responsibility for conveyor, reject and x-ray systems is that it allows such issues to be addressed at the design stage.
