Mettler-Toledo DXD and DXD+ dual energy detector technology

Mettler-Toledo Product Inspection has launched its latest advanced X-ray inspection technology, which has the ability to detect low-density contaminants in packaged food products. The technology is designed to help food manufacturers avoid product recalls, reduce unnecessary product waste costs and enhance product integrity and brand protection.

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.

Such applications are suitable for DXD and DXD+ advanced detector technology, in conjunction with intuitive Mettler-Toledo Advanced Material Discrimination software tools. The software helps to separate and remove the prominent material of the food product within the X-ray image, revealing the presence of any lower-density contaminants. Food manufacturers will benefit from reduced false reject rates and product waste.

The performance of the technology has been tested by the company on a range of different foreign bodies hidden in 650 g packs of chicken breasts.

The advanced detector technology is available in two versions. DXD enhanced X-ray performance can operate in the same environments as single energy solutions and can be used with line speeds typically up to 100 m/min. DXD+ premium detector technology is suitable for challenging applications; collects more data about the product being inspected and advanced image analysis software provides clearer images with higher resolution; and it can be used with line speeds typically up to 45 m/min.

Both the dual energy detectors can now 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.

Mettler-Toledo is offering personalised consultations to prospective users of this latest technology either on a 1:1 basis at its Royston facility or virtually. The consultations will include live testing with users’ actual products, as well as the opportunity to engage with experts in the X-ray inspection field.
