Mettler-Toledo Product Inspection has launched a series of metal detection systems for the food inspection market designed specifically for small and medium-size manufacturers and/or co-packers.

The modular design of the fully integrated system can be adapted over time in line with evolving compliance and productivity needs. This positions the M30 R-Series GC as an entry-level metal detection solution for manufacturers, with future-proof flexibility built in. 

The new metal detection systems feature a digital platform, powered by Sense software. This, combined with advanced algorithms, makes it possible for these entry-level models to deliver high sensitivity to all metal contaminant types with minimal false rejects.

Dynamic stability control innovations stabilize the core sensor of the metal detector to help protect against environmental noise and vibration interference for increased reliability.  The entry-level M30 R-series GC systems are designed on a modular platform concept with streamlined features as standard. The metal detector and conveyor can be upgraded as compliance or production requirements change. This helps manufacturers achieve a lower overall cost of ownership and extend the useful life of their equipment, supporting sustainability aims. 

“Sense really is a game-changer in the metal detection field,” ​said Mike Bradley, metal detection systems product inspection specialist at Mettler-Toledo Product Inspection.

“Just like a human brain, it commands the neural network within these digital inspection systems and integrated GC Series conveyors. It takes control of the entire metal detection system to unprecedented levels, making judgements and decisions, learning all the time, and constantly harmonizing and optimizing every aspect of the operation.” 

The M30 R-Series is the first product family from Mettler-Toledo Product Inspection built around the Sense software technology. The company said the color touchscreen makes operation simple, with key tasks accessible using a quick-access menu. Localization at individual user level, including a choice of 33 languages as standard, reduces error risk and improves productivity. The new metal detection systems offer three levels of ingress protection from IP65 to IP69K to support long-term, reliable performance in a range of manufacturing environments.

The M30 R-Series consists of four metal detector models matched to different production and compliance needs, and budget considerations.

 The M31R StandardLine is designed for versatile, reliable inspection in all food segments; high frequency, tuned technology with eDrive that delivers up to 10% spherical sensitivity improvement over legacy models.

The M33R PlusLine features very high frequency tuned technology and eDrive to deliver an up to 20% improvement in spherical sensitivity performance: this is suitable for dry applications such as cereal bars, dry pasta, confectionery and snacks.

The M33RB PlusLine includes very high frequency tuned technology and eDrive, combined with optimized case/coil geometry to deliver up to 30% improved spherical sensitivity performance in bulk applications such as crates of meat and 25kg sacks of flour.

The M34R PlusLine uses dual-simultaneous frequency and product signal suppression technology to improve spherical sensitivity performance by up to 25% and reduce false rejects in wet or conductive applications; tailored to wet, challenging and conductive applications such as dairy, meat, poultry, and seafood products with high salt content and those packed in metallized film.

The metal detectors can be integrated with a range of conveyor systems including Mettler-Toledo’s recently enhanced GC Series systems. This modular conveyor system solution now includes new features such as extended belt lengths, a non-hollow frame option and a wider range of reject devices including an overhead sweep and retracting band. 

“Food processors, FMCG manufacturers and co-packers have long thought that to acquire advanced metal detection capabilities they would have to spend a lot of money on a high-end system,”​ Bradley said.

“With the launch of our M30 R-Series metal detection systems, that is no longer the case. They can now invest in a smart, digital metal detection system that gives them highly advanced capabilities at an attractive price. This is next-generation metal detection that will protect their brand, their processes and their profits.”
