Longhini Preserves Sausage Quality with State-of-the-Art Metal Detectors from Mettler-Toledo Safeline

Longhini Sausage Company, a maker of Italian sausages and other specialty meat products, takes pride in maintaining the high standards set forth by their founder almost 70 years ago. To help ensure their product quality and support their growing customer base, Longhini installed two new Profile Advantage metal detectors from Mettler-Toledo Safeline.

“Our application is difficult for most metal detectors. Meat products have natural variations in temperature and moisture, plus our wide range of case sizes presents a variation in product density. Products with variable characteristics are hard to accurately inspect,” said Rich Longhini, president of Longhini. “To overcome these challenges, we had to find an unusually advanced metal detector.”

Longhini purchased their first Profile Advantage in 2015. Then in 2019, it purchased a second Profile Advantage on wheels, but this one is rolled around and integrated with various lines throughout the facility to fully-automate inspection. The first, off-line system reportedly exclusively inspects cases filled with either bulk sausages or tray packs not already inspected by the inline system.

As Mettler-Toledo’s top-of-the-line metal detector, the Profile Advantage is reportedly unmatched in identifying and rejecting every type of metal in even the most difficult applications.

Compared to traditional single-frequency systems, Profile Advantage is reportedly better able to discern changes due to the presence of metal versus natural variations within the product by using multi-simultaneous frequencies to create a reference point. This advanced operation maximizes sensitivity while virtually eliminating false rejects when inspecting all kinds of products.

“One of our favorite Profile Advantage features is the ‘product clustering’ capability, which allows us to run many similar products under the exact same setting. We can almost always lump new products together under existing product settings,” said David Kemp, CEO of Longhini. “We also like the auto-setup routine. With it, our operators can easily add totally new products or recalibrate in less than five minutes.”
