INSPECTION & WEIGHING
causing it to make a double bag and halt, leading to wasted product along with the contamination or test samples. To overcome this issue CEIA’s metal detectors offer fully automated testing and digital integration. The testing frequency can be set to meet specific application requirements, typically every hour, but customisable to every 30 minutes or other interval. Every automated test conducted is also digitally recorded, providing an audit trail. In the snacks and confectionery industries, where production speed and product integrity are critical, automated testing and continuous sensitivity monitoring can offer advantages. By reducing manual intervention, minimising product waste, and providing audit trails they can help maintain high standards of safety and quality while also optimising operational efficiency.
A delightful solution Turkish company, HazerBaba was one of the and techniques to produce turkish delight and it is one of the most well-known Turkish delight brands across the globe. The success of the brand led to a need for rapid manufacturing growth resulting in the inspection equipment needing to be able to handle increased production volumes and a growing range of products. Due to this growth, the company made the decision to upscale to new facilities and upgrade its production capabilities, including the Critical Control Points (CCPs) of its inspection systems. This was important for the company as it was one of the few companies in Turkey to hold both ISO 9001:2015 and 22000:2005 quality Having previously used Loma product inspection equipment, the company made the decision to specify its latest metal detection solution – with built-in reject functionality – for inspection across multiple production lines at the site. LOMA recommended a metal detector conveyor solution, designed to inspect both packaged and loose products. The system is able to detect ferrous and non-ferrous metals as well as stainless steels, in fresh and frozen products, either unwrapped or wrapped, even in metalized films, delivering the inspection flexibility that was important to HazerBaba. “We have worked hard to establish a

good reputation, and the installation of the new inspection system has enabled us to further protect our expanding business with improved detection,” says Ayse Saglam, Export Manager at HazerBaba. The new metal detector enabled the company to increase its overall equipment effectiveness (OEE), enabling adherence to stringent quality certifications. The solution can store multiple product credentials which has helped to increase the speed of product changeovers.
X-rated information As already mentioned, the use of X-ray inspection systems across the food recent years, as more retailers mandate use of the technology by brands they stock. In addition to recognising contaminants such as metal, glass, rubber, stones, plastic parts or bone splinters, they also enable inline quality checks, such as weight determination, counting of components, detection of missing or defective products, fill level control and checking the integrity of closures. As part of the HACCP concept (Hazard Analysis and Critical Control Points), they help to fulfil the increasing requirements of consumers and authorities and protect companies from costly and brand- damaging product recalls. X-ray machines in the food industry work in much the same way that X-ray machines at airports check luggage for
security reasons. The product runs on a conveyor belt at a constant speed through the X-ray beam. As the product continues to move, a new image line is generated at regular intervals. Once the product has been fully recorded, the greyscale image generated is analysed and inspected for foreign objects. “X-ray inspection systems recognise contaminated products by the fact that foreign bodies such as metal absorb X-rays more than the actual food product,” explains Liang Mengqi, Global Product Manager at Minebea Intec. “Hence, the success of foreign body detection depends on the density of the foreign bodies. For example, an X-ray machine could detect 2mm metal wire inside a yoghurt carton, where a conventional metal detector would not be able to, because the metal detector would be stopped due to the aluminium foil from the packaging. To select a suitable X-ray system for an application, the product and its orientation first need to be considered. Systems with top-mounted X-ray generators are the most commonly used variant in the food industry, where the X-ray beam hits the product directly from above. These inspection systems are usually installed at the end of a production line and inspect the packaged products. For this purpose, the packs are positioned flat on the belt so that the X-ray beam could pass through as less pack thickness as possible, which
