    What is a 'Food' Metal Detector?

    Metal is one of the most common contaminants found in food and can be introduced at almost all stages of food production. Sources of metal contamination can include raw materials, personal effects, maintenance and in-plant processing. Metal detectors are used within the food production industry to identify unwanted metal in food and safely remove any contaminated products from the production line before they leave the factory, ensuring food is safe for consumers.

    Food metal detectors can be combined with a variety of transport mechanisms including conveyors, pipelines, gravity-fed and free-fall vertical systems and can be integrated with reject devices to provide complete detection and rejection solutions.

    When manufacturers develop a metal detection program, it is important to consider the reliability, stability and sensitivity of the food metal detector to ensure metal is effectively detected. Factors which can compromise the detection of unwanted metal include the orientation of the metal object as it travels through the metal detector, and product effect such as product acidity, temperature, moisture content and specialized packaging such as metalized film.

    METTLER TOLEDO Safeline has a number of innovative solutions to support these factors, including its Profile Advantage metal detector which is specially designed for challenging applications.

    Metal Detector Testing Procedure

    METTLER TOLEDO offers a wide range of products and services designed to support manufacturers in ensuring compliance with regulatory standards, and provides guidance on metal detector testing procedures.

    It is important that manufacturers understand how to verify the performance of their metal detectors; if the system is not correctly tested at regular intervals, manufacturers run the risk of failing to comply with standards which could pose a serious threat to their business.

    Retailer test processes such as the large metal test and consecutive pack test are built into all METTLER TOLEDO Safeline metal detectors as standard to ensure easier compliance with major retailer codes of practice.

    When implementing a metal detection test procedure, manufacturers must firstly ensure their metal detector meets the required detection standards and are set up within the sensitivity guidelines.

    Testing procedure checks include detector performance levels and complete system integrity/functionality.

    There are no mandatory guidelines on the frequency of tests, unless these have been identified by a retailer code of practice or by requirements from a customer or external agency. However, it is recommended that testing is carried out at the start and end of each shift and of each new product run.

    Safeline metal detectors provide advanced warning of when tests are due and has introduced two new enhancements to its Profile metal detectors – Reduced Test and Automatic Test System (ATS).

    Using Reduced Test mode, Safeline metal detectors operate at a higher sensitivity level than the customer's specification which allows the frequency of performance monitoring tests to be reduced by up to 83%.

    ATS reduces the time taken to conduct routine tests from 3-5 minutes to less than 40 seconds for a 3 metal test.

    Metal Detector Validation Procedure

    Validation is the initial qualification of a product or process against the stated design specification and belongs at the start of the equipment lifecycle when it is first installed into the production line. Re-validation may also be required if substantial modifications to the equipment, or the products being inspected (size, packaging material, etc.) are made at any point after installation.

    Validation procedures usually involve both internal and external parties. A well-executed and carefully carried out installation phase is the foundation of worry-free and efficient use of the metal detector. Therefore, equipment manufacturers are in a strong position to support their customers throughout the installation/start-up process by making sure that the equipment:

    • Is capable of detecting the relevant foreign body contaminant types which may occur in the products being produced (the food manufacturer must ensure the correct product inspection equipment has been chosen for the application).
    • Complies with relevant industry standards and regulations.
    • Complies with quality management system audits and relevant legislation applicable to the country in which the equipment is installed.
    • Supports proof of due diligence.
    • Operates as intended when at factory default settings aligned to the customer's product.
    • Is adjusted properly so that the equipment operates as intended, and to the specification set.
    • Is installed correctly with reference to system peripheral devices and reject systems.
    • Can be used properly and effectively by operators, so that they can enjoy maximum benefit from the features that the metal detector offers.

    METTLER TOLEDO offers a wide range of products and services designed to support manufacturers in ensuring compliance with regulatory standards, and provides guidance on the validation, verification and monitoring for product inspection equipment.
