Mettler-Toledo X3 Series X-ray inspection systems

Mettler-Toledo Product Inspection has released the X3 Series of bulk flow X-ray inspection systems, designed to deliver physical contamination detection, precision waste reduction and simplified operation. Consisting of the X13 and X53 models, the series offers hygienic design, streamlined usability and the advanced performance required by agriculture, confectionery and dried food producers worldwide.

Designed for bulk food applications, the system has been developed for unpackaged, loose-flow, bulk products on conveyors. Both systems in the series can detect contaminants as small as 0.3–0.4 mm (depending on application and contaminant material), protecting equipment, preventing recalls and supporting compliance with global safety standards. Typical applications include dried, fresh or frozen fruits and vegetables; nuts; pulses; root vegetables such as carrots and potatoes; confectionery; and cereals.

Reject options include a 30-nozzle air blast for pinpoint removal of contaminants in smaller products, or a 6-flap pusher reject for the removal of contamination in larger produce. With reject devices positioned above the product, they are less likely to become blocked or clogged with product debris, thereby maintaining performance and supporting hygienic handling.

With throughput rates of up to 5000 kg/h, both systems include tool-free belt and guide removal to simplify cleaning routines.

The X13 combines powerful detection with an affordable price point. Equipped with HiGain+ detector technology and ContamPlus software, it delivers sharp imaging and detection of physical contaminants such as metal, glass, calcified bone and stone in a large variety of bulk flow applications, regardless of consistency or format.

As the premium solution from the range, the X53 is engineered for manufacturers who handle the most complex bulk products and require high-level accuracy. It builds on the X13 and integrates HiGain+ DE (Dual Energy) detector technology and AMD (Advanced Material Discrimination) Pro software to deliver an additional layer of analytical intelligence. By processing two energy spectrums simultaneously, the X53 can differentiate between materials with similar densities, such as bone and product, allowing it to detect challenging low-density contaminants that single-energy systems may miss. It also introduces enhanced traceability and automation features, including product validation routines, self-checking performance verification and a fully lockable inspection tunnel for secure operation. 

Both models feature front-open conveyor access and tool-free removal of key components. Options such as belt scrapers, water-cleaning systems and removable guide rails make sanitation fast and effective, while integrated cable management reduces clutter. Each system is available with a choice of ingress protection ratings up to IP69, providing flexibility to suit different hygiene standards and cleaning regimes.
