Mettler-Toledo Safeline HDS pipeline metal detectors

Mettler-Toledo Safeline has developed a range of HDS Pipeline Detectors based on its Signature platform. This pipeline metal detection solution was originally developed specifically for use on vacuum filling lines where it delivers detection sensitivity and stability, as well as user-friendly operation in potentially harsh or extreme working environments.

Designed for easy integration with all leading vacuum fillers and other processing equipment, the metal detection system offers consistent and reliable performance. Featuring a full stainless steel construction and sealed to IP69K, the systems are capable of withstanding extreme conditions and stringent washdown regimes required in meat and food processing plants, according to the company.

The detection coil technology and Signature software platform deliver high sensitivity to all metal types. In addition, the product is capable of detecting non-spherical contaminants such as metal clips, wire, swarf and slivers of metal introduced during grinding processes, which have traditionally proved difficult to locate due to a phenomenon known as the ‘orientation effect’.

The short overall length of the throughput tube and utilisation of the zero metal-free zone (ZMFZ) technology minimises product ‘creaming’ (uneven distribution of fats towards the outside of the product). This also enables metal fittings and other process equipment to be positioned in close proximity to the detection head without compromising detector performance.

The product’s slim design and compact footprint allow it to fit into the tightest of environments alongside leading vacuum fillers. Four robust castors offer 360° rotation, facilitating easy withdrawal from the process for cleaning and relocation to other lines if required. Furthermore, flexible height adjustment allows the detection head to be raised or lowered via a gas-strut to link up with the vacuum filler outlet.

All of the company’s systems incorporate ‘stop-on-detect’ functionality. This means that if metal is detected, a signal will be generated to control vacuum filler operation, enabling contaminated product to be purged from the pipeline.

The product can be connected to a wide range of factory data management solutions via Ethernet technology to support compliance with leading food industry standards, regulations and legislation. Manufacturers can also use this connectivity to record performance data and to confirm test routines have been completed for complete product traceability and proof of due diligence.
