When it comes to HACCP inspection machine choices, the options can seem overwhelming.
However, given that metal can be introduced at any phase of production, for example, during cutting meat, filleting fish, grinding spices, or mixing dry and wet ingredients, a metal detection system is normally the first line of defence.
Calculating the actual cost of a food recall is challenging, as no incident is the same as the next. Additionally, manufacturers must consider the scale of the recall, including the number of customers potentially affected by the contaminated product, the stage at which the recall is initiated, any fines or penalties incurred, and the resulting drain on resources and business interruption at the production plant.
Supply chain transparency and the speed at which the source of a metal contaminant is identified are imperative and can minimise damage to a brand's reputation.
When considering an investment in metal detectors, choose a kit that reflects the most prevalent contaminant risks. Also, thoroughly investigate the long-term service costs and upgrade options. Choosing a locally based machinery supplier with strong R&D capabilities and experience can be invaluable.
Other inspection strategies include:
Select inspection equipment with inbuilt record-keeping
Look for systems that will track and record rejects, tests, and settings. This type of software facilitates the documenting of potential product risks and helps to narrow the time frame during which a problem can go undetected. It also reduces the amount of suspect product that must be discarded or recalled in the event of an incident.
Choose the correct reject system
The type of reject device used will depend on multiple factors, including pack size, weight, and shape, whether the product is free-flowing or packaged, factory layout, size and floor space, as well as line pitch, speed, and belt width of the conveyor.
Test machine performance automatically
If a fault with the reject system causes a contaminant to be detected but not rejected, the line should stop automatically until the issue is resolved. Both detector performance and fail-safe capabilities should be tested regularly, ideally complemented with an automated test system like Halo Automatic Testing.
This helps to increase the frequency and quality of verifications while also removing the risk of human error and workplace injury at critical control points. Ultimately, ensuring compliance with industry standards is crucial.
Watch for false rejects
Ensure that when a line stops due to the detection of metal, there is an issue to address. Technologies like simultaneous multi-frequency enable producers of conductive products, such as meat, dairy, and prepared foods, to combine maximum detection sensitivity with minimal false rejects.
Ask about product lifecycle compatibility
