X-ray detection for hard-to-find contaminants

10 October 2022

Mettler-Toledo Product Inspection has launched its most advanced x-ray inspection technology to date, delivering the ability to detect low density contaminants in packaged food products. 

Mettler-Toledo DXD and DXD+ dual energy detector technology is optimised for identifying foreign bodies such as calcified bone, low-mineral glass, rubber and some plastics. These types of contaminants are traditionally hard to detect within the ‘cluttered’ or ‘noisy’ x-ray images generated by overlapping and multi-textured products such as packs of pasta, chicken breasts, sausages and frozen potato-based goods. 

The x-ray detectors cn be used in conjunction with new Mettler-Toledo Advanced Material Discrimination software tools, which helps separate and remove the prominent material of the food product within the x-ray image, revealing the presence of any lower density contaminants. 

DXD and DXD+ dual energy detectors can be specified with new purchases of Mettler-Toledo X36 x-ray systems. Only a small amount of extra operator training is required due to automatic job set-up and the similarities between the Advanced Material Discrimination software and the ContamPlus software that is familiar to existing Mettler-Toledo x-ray users.
