Europe: Mettler Toledo’s new detector manages active product signals

SHARE

Mettler Toledo Safeline Metal Detection launches the Profile Advantage metal detector that utilizes the Multi Simultaneous Frequency technology to deliver up to 50% greater detection sensitivity than traditional metal detection technology.

This ensures meeting the requirements of standards, such as British Retail Consortium (BRC), International Featured Standard (IFS), the U.S. Food Safety Modernization Act and Retailer Codes of Practice.

Traditionally, foods with a high moisture or salt content, such as baked goods, or those packaged in metallized film, have proven a challenge for conventional metal detectors, as they produce an ‘active product signal’, commonly referred to as a ‘product effect’.

This is where the presence of this signal can reduce a metal detector’s ability to detect the very smallest pieces of metal contaminants leading to potentially costly and reputation-damaging product recalls.

The Profile Advantage is able to effectively eliminate the active product signal to achieve sensitivity levels previously associated with the inspection of ‘dry’ or non-conductive products.

The system’s Product Signal Suppression feature allows the system to modify the product signal during product set-up so that it appears to be similar to that of a non-conductive or dry product.

This in turn delivers levels of system sensitivity to all metal types including contaminants such as wires and slithers of metal.

To support the drive to increase OEE, the Profile Advantage employs sophisticated software 3S Algorithm, which is applied to every product that passes through the metal detector, so as to make the active product signal mimic the product signal captured during the auto set-up routine.

As a result, the incidence of false triggering due to inherent variations in baked products can be virtually eliminated, minimizing product waste and therefore boosting manufacturing OEE through an increase in productivity.

The system comprises Predictive Analytics that allows users to dramatically reduce the number of scheduled performance monitoring tests it undertakes by analyzing the performance (sensitivity) of the metal detector and producing an alarm should the system identify a change that could result in a reduction in the system sensitivity.

A reduction in the frequency of metal detector testing for manufacturers from, for example, six times a day to twice a day, could result in savings and efficiencies.

The Profile Advantage conveyor solution is compliant with Hazard Analysis and Critical Control Points methodology, featuring hygienic design features of curved corners and sloping surfaces to minimize dirt traps and facilitate quick and easy cleaning.

Constructed entirely in stainless steel, the system is available with ingress protection rating, IP65 or IP69K.

Supplied with Mettler-Toledo’s PROD X data management system performance monitoring data can be collated automatically and stored centrally, generating reports for due diligence purposes.
