In the bustling realm of frozen food production, quality control stands as the linchpin between a delectable, crispy batch of French fries and a culinary disappointment. For one of the leading international suppliers of frozen retail, wholesale, and food-service potato products, ensuring the pinnacle of product integrity and premium quality has reached new heights thanks to Fortress Technology’s groundbreaking automatic testing solution.
Picture this: more than two dozen highly sensitive Stealth metal detectors, each armed with customized reject conveyors and the cutting-edge Halo Automatic Testing, are strategically placed along the processing lines. These detectors oversee the production of an array of delectable delights, from French fries to hash browns, ensuring that every product that reaches your plate is of unmatched quality.

What sets this system apart is its unparalleled efficiency. Every hour, each metal detector autonomously performs up to nine machine validation tests. That’s 180 or more repeatable tests on various SKUs and different-sized bags of French fries, ranging from 225 grams to a substantial 9 kilograms. This meticulous testing process is all thanks to the deployment of Halo Automatic Testing, a technology that not only streamlines the quality check process but also minimizes wastage.
Traditionally, testing the performance of conveyor metal detectors involved manual labor, a process both time-consuming and resource-intensive. However, with the introduction of Halo, this frozen fries factory can now program and conform to every customer’s performance verification testing program. This includes independently testing all three metals in various positions within the product bags—a critical requirement set by discerning clients like fast-food chains.
The key challenge addressed by this innovative approach is the ‘product effect.’ In large, bulky frozen products weighing up to nine kilograms, a single test might lead to an excessive number of false rejects. By testing all three metals in three different positions, the system ensures that the metal samples are not masked by the product, confirming the accuracy of the reject system. This is especially vital in bulk frozen products, where characteristics might change due to slight thawing during the inspection phase.
Fortress Technology’s Commercial Manager, Jodie Curry, emphasizes the importance of this methodology, stating, “Testing all three metals in three positions ensures the metal samples are not being masked by the product in any position and also confirms that the reject system is tracking correctly. This is especially important in frozen bulk products when the characteristics might change due to slight thawing during the inspection phase.”
This technological leap not only signifies a paradigm shift in quality control within the frozen food industry but also heralds a new era of efficiency and precision. With Fortress Technology’s automatic testing solution, the journey from farm to freezer to table is now imbued with a level of assurance and quality that consumers can trust.
