How Approved Metal Detector Testing Can Improve Your Business

Investing in an approved metal detection automatic test system is essential if you want to ensure your equipment is working correctly, every time. Automatic test systems ensure you are meeting compliance needs, whilst increasing productivity and improving product quality.

Product inspection equipment is a necessity for most food processors. Having equipment such as metal detectors on a production line helps to comply with GFSI-based food safety standards and retailer codes of practice, and ensure complete product quality and consumer safety.

Manufacturers need to ensure their metal detectors are working correctly in order to deliver compliance and safety assurances, as well as ensuring products remain of a high quality. Performance monitoring is an essential process for all food processors, however testing often involves stopping production or wasting good product, both of which can have a negative impact on overall equipment effectiveness.

The challenge that many food producers face when using Gravity Fall and Throat metal detectors for raw ingredients, is how can they truly confirm centerline (worst-case) sensitivity of their metal detectors when conducting performance-monitoring tests?

Without that confirmation, they cannot be sure they are reliably protecting their customers and their brands. Additionally, every time a test is carried out, there can be an impact on productivity and labor costs. Tests often require a stop in production for multiple minutes, and two operators are often required to physically carry out the tests. The higher the frequency of testing, the bigger the impact it has on productivity and profitability, and the larger the volume of associated product waste. 

How the latest metal detection innovations make routine testing easier

Innovative metal detector testing solutions such Automatic Test System (ATS) and Reduced Test (RT) Mode are designed to improve the accuracy of tests, reduce the frequency of testing required and lessen the time it takes to carry out the tests respectively.

Award winning and approved by a major UK retailer, ATS is a non-invasive method of testing recently launched by METTLER TOLEDO. It is the only way that the company believes confirms centerline sensitivity to ensure maximum brand protection. 

The Automatic Test System (ATS) and Reduced Test (RT) Mode are designed to improve the accuracy of tests

It eliminates the random nature of vertical metal detector testing by providing a controlled and repeatable process. It also removes the risk of cross-contamination and product waste as the test pieces do not pass inside the product flow. ATS also reduces the time taken to conduct testing from three to four minutes to less than 40 seconds. As well as improving productivity and product safety, labor costs are reduced, as only one operative now needs to carry out testing. Worker safety is also enhanced due to the reduction of ladder climbs and working at height.

RT is another recent testing innovation from METTLER TOLEDO. It uses intelligent software to continuously check the performance of the metal detector to ensure it is always working to, or better than, the manufacturer’s specification. RT ensures the metal detector is always functioning correctly, and alerts any status changes that may lead to a drop in performance before the metal detector operates out of specification.

Drivers for change

Productivity and product quality are two of the key drivers for food processors, alongside cost reduction. If a business can reduce costs and increase operator efficiency to allow them to carry out more production related functions, rather than test functions, there is a direct correlation with profitability. These latest testing innovations as a whole deliver cost-down, productivity-up benefits, whilst ensuring maximum product quality and brand protection.
