to future-proof their operations. This is an especially beneficial solution when floor space is limited.” Fully integrated solutions will typically


leverage AI technology and digital data collection, with these features enhancing operational efficiency and supporting greater traceability across the production chain. “The new Raptor Tritek system exemplifies the benefits of these technologies,” continued Phil. “Integrating metal detection, checkweighing and vision inspection within a single 2.5m stainless steel frame, it stands at least 40% shorter than modular combination configurations. Additionally, the system prioritises ‘safety- first’ as it features a unique ‘Conveyor Run Only Mode’ to ensure HACCP-mandated metal detection remains continuously active even if the checkweigher is offline.”


Vision inspection Since label errors typically account for the greatest number of product recalls, vision systems are increasingly being considered an important element of any product inspection solution. “When employed in a combined system, such as the Raptor Tritek, it can provide a more complete inspection picture, including context,” continued Phil. “For example, all-in-one systems can collect detailed data on every individual pack, including its weight, size, visual


integrity


and any contaminant detection results. A vision system might also be able to identify when and why confectionery packs are under or overweight. This level of complete transparency is unprecedented compared to installing separate machines.” Pointing out a key trend that is affecting


quality control, Phil highlighted the transition


from manual record-keeping


to digital ecosystems. “Modern factories are increasingly reliant on ‘bi-directional’ communication, where end-of-line data informs upstream processes and supports complete traceability,” he said. Here, technical solutions like Contact 4.0, OPC UA Adapters and Ethernet/IP Adapters allow data to flow seamlessly across networked metal detectors, checkweighers and combination systems. “Having the ability to identify the root causes of waste or contamination in real time helps ensure that inspection equipment remains an active participant in supply chain quality control,” concluded Phil.


Inspection issues One of the most commonly encountered inspection issues within confectionery production is foreign body contamination. Raw materials such as nuts, cocoa, sugar and fruit ingredients can introduce risks including


metal fragments, stones, glass or dense plastic particles. In addition, wear and tear from processing equipment can also generate contamination risks during manufacturing. Modern inspection technologies therefore play a critical role in safeguarding both products and brands to help overcome one of the biggest challenges for confectionery manufacturers – balancing extremely high production throughput with uncompromising quality control. “Consumers expect absolute consistency from every product they buy, while retailers and regulators demand increasingly robust inspection and traceability processes,” said Sion Titley, Solutions Specialist at Bizerba UK. “Foreign body detection remains a top priority across the confectionery sector. Manufacturers need inspection systems that can reliably


detect contaminants without interrupting production efficiency, particularly on fast- moving lines where products can vary greatly in shape, density and packaging type.” There is a huge range of advanced


inspection solutions available today that can help significantly reduce these risks. Bizerba Inspection Technology, for example, can combine dynamic checkweighing, metal detection, X-ray inspection and vision inspection systems to provide comprehensive inline quality assurance throughout the production process. Weight consistency is also an important


quality control issue for confectionery manufacturers. Underfilled packs


can


lead to compliance issues and customer complaints, while overfilling directly impacts profitability through product


MAG’M has adopted two advanced X-ray systems to meet Japan’s stringent quality control expectations, achieving detection of contaminants down to 0.4mm.
