Single Frequency Metal Detector Works Best for Dry or Frozen Food

New technology provides a high level of metal detection for food safety, reducing the risk of costly recalls due to contamination.

Thermo Fischer Scientific Sentinel 1000 Metal Detector

Making its debut at PACK EXPO Connects, Thermo Scientific’s Sentinel 1000 Selectscan metal detector employs fully flexible frequency optimization per application with frequencies from 50 to 1,000 kilohertz. “With a single frequency metal detector, you only have one chance to pick the right frequency that fosters the highest level of metal detection,” says Alex Kinne, applications engineer for Thermo’s product inspection division. Processors can also use Thermo’s Auto Learn feature to pick the frequency, Kinne explains.

“Customers need flexible inspection solutions that don’t compromise performance,” states Kinne. “Often, customers will run multiple products on the same line in the same day. So, Selectscan technology was developed around the principles of performance, efficiency, and ease of use.”

The Selectscan metal detector works well for dry, inert products that have relatively low product effect, such as dry pasta or frozen foods. The Selectscan’s single frequency is optimized per application. “If you change product files, you may choose or may change frequencies to a different, yet optimized, frequency,” Kinne adds.
