Metal detector overscomes ‘product effect’

A new metal detector range was launched by Fortress Technology at last month’s Processing & Packaging Machinery Association show in Birmingham which is claimed to take wet food inspection to a new level of sensitivity.

Conquering the longstanding challenge of ‘product effect’ caused by moisture and minerals, the Interceptor range is specifically designed to inspect conductive applications including cheese, puddings, yogurts and ice cream, helping to eliminate false rejects.

Increasing stainless steel detection by 100%, Fortress’s latest technology splits the frequency signals. This means that the machine can clearly differentiate between the signal generated by the product as a result of moisture or mineral content (for example salt that’s prevalent in many cheeses) and any metal contaminant. This puts a stop to a potential stainless steel signal being ‘swamped’ by product effect.

The sensitivity of the Interceptor means it can pick up metal contaminants half the dimensional size previously identifiable.
