Metal detector proves sensitive and
reliable
Contract packer, Grange Packaging and Distribution, has purchased some Mettler Toledo Safeline R series Signature metal detectors to check there are no metal particles in packaged chocolate powder.
Contract packer, Grange Packaging and Distribution, has replaced its existing metal detectors with Mettler Toledo's Safeline R series Signature detectors Positioned over the conveyor, they search for metal particles in packaged chocolate powder prior to shipping

Metal detector maintains sensitivity
A metal detector from Mettler Toledo is well suited to food production and packaging line use, with the sensitivity needed for the application and featuring high frequency coil technology.
"We are required by one of our most important clients to use metal detection in our production process," commented Grange Packaging's QA Manager Shirley Mercer.
"The previous detectors we were using were unable to reach the sensitivity we wanted to achieve.
To improve our processing systems and our CCPs a decision was made to change our Metal Detectors to Mettler Toledo Safeline.

The company's Safeline R Series Signature detectors have proved very reliable since they were installed last December.
They are extremely sensitive to even the smallest metal particles and give us the peace of mind to know that our packaged products are completely food safe.
They were easy to install on our existing production line with minimal disruption and are also simple to use.
I have also been very pleased with the excellent service and support we have received from Mettler Toledo Safeline," she added.
Metal fragments can enter the product during manufacturing or co-processing and it is essential that any contaminated packs are removed.
Inspecting over 60,000 packs a day, the detectors simply fit over the conveyor, and if a contaminated pack is discovered it is rejected from the line by an air blast.
The R Series Signature can detect the most minute particles of metal, even through several layers of packaging.
It does this through high frequency detection coil technology combined with enhanced filtering techniques.
This provides unparalleled online sensitivity to all metal types, including normally difficult-to-detect non-magnetic stainless steels and non-spherical contaminants like wire, swarf or small slithers of metal.
Through its single-setting operation, the detector can inspect multiple products with different product signals without the need for adjustment or programme changes, a major advantage over similar systems.
Another advantage of the R Series Signature is that the units can work in close proximity to other metal structures and equipment without any interference - ideal for situations where space is very restricted.
This is achieved through Safeline's revolutionary Zero Metal Free Zone (ZMFZ) technology, which generates an internal cancellation in opposition to the primary metal field of the detector.
This inhibits the leak of the unit's magnetic feed, reducing the insertion space required.
Future proofing is an integral part of the detectors' design.
Their multi-frequency capability allows them to inspect products packaged in both plain and metallised film, while a broad array of connectivity options ensure the R Series Signature range meets future requirements in terms of data capture and management information systems.
Each unit has an in-built performance validation routine in line with the requirements of HACCP (Hazard Analysis Critical Control Point) areas, GMP (Good Manufacturing Practice) and all the major food retailers.
It automatically tells the user when scheduled testing is due and guides QA staff through the process step by step. Request a free brochure from Mettler Toledo ...
