Bringing inspection solutions up to speed
Suzanne Callander reports on how inspection technology has advanced in recent years to ensure that keeps pace with modern packaging systems. If your inspection solution is the weak link in your production line, read on...

ne of the issues facing confectionery manufacturers in recent times has been the fact that product inspection system advances have not been keeping pace with the rapidly increasing productivity being offered with modern packaging systems such as high-speed flow-wrapping machines and pack sealers. Ultimately, a production line can only ever run as quickly as its slowest component and this has led to considerable R&D effort by product inspection machinery suppliers. The result of this development work is now available for confectionery producers in the form of the latest generation of inspection systems such as metal detection systems designed specifically for accurate detection at high speeds of ferrous and non-ferrous metals in addition to stainless- steel contaminants which may come from the production line itself. There are also metal detectors on the market now which have been developed specifically for the inspection of small, individually packaged products, including spherical products,

at high speed – so are well-suited for use in confectionery inspection applications.
“In addition to the welcome boost to production capacity and detection sensitivity that these high-performance systems can deliver for confectionery manufacturers, further improvements in built-in rejection systems can also reduce waste in the process,” says Juergen Kress, General Manager for Checkweighing and Vision Inspection at Mettler-Toledo Product Inspection. “Operating at the same speed as the inspection machine, the use of such mechanisms means that single confectionery bars can be rejected at the point a contaminant is detected, instead of entire multi-packs having to be rejected later in the packaging line.” Juergen went on to point out another important factor that makes these high-speed inspection systems attractive to the confectionery market – many now have a compact footprint, enabling them to be fitted into the limited space that is a reality on many confectionery production
