food industry use horizontal metal detecting machine

When it comes to packing systems for the food industry, customers generally require checking machines, like a check weigher and a metal detector. A metal detector is for detecting metal objects among the finished products.

What are the main differences between metal detection and X-ray inspection?

Although both X-ray inspection and metal detection are used to check for contaminants within food and pharmaceutical products, the technologies have different capabilities and advantages. Each technology will be important for different reasons depending on the application and situation. Metal detectors are principally used when only detection of metal contaminants is required, which is why they tend to be the cheaper option and as technology has moved on over the years the contaminant sizes that can be achieved are very good. Alternatively, X-ray inspection systems offer the ability to not only detect for all metals, but other contaminants such as bone, ceramic, glass and dense plastics based on their density. X-ray inspection is also capable of checking product integrity – making sure the product is complete and free of defects. It is also worth noting X-ray inspection systems can typically reliably see smaller contaminants in harder to inspect products compared with a metal detector.
