Metal Detection in the Food Industry
Metal Detectors ideal for the food, pharmaceutical & packaging industry
Ever since LOMA SYSTEMS® was founded in 1969, the company has worked very closely with both food manufacturers and retailers around the world to deliver leading inspection solutions. As a result, LOMA® has an unrivaled level of experience and expertise in the practice of effective metal detection within food industry production lines.
In the food production industry, metal is one of the most commonly found contaminant materials in food. Metal can be introduced at all stages of processing of food, as it is most commonly used in the construction of machinery, handling equipment and ancillary utensils.
A metal detector for the food industry can help ensure the safety and integrity of a wide range of unpackaged, packaged or bulk goods, by identifying metal contaminants during processing or packaging and helping to ensure that they do not enter food that we eat. As part of a HACCP program, metal detection systems can be utilised to provide compliance with food safety standards (GFSI, BRC, IFS), retailers’ code of practice, legislation and industry guidance.
For the pharmaceutical industry, please see our Pharmaceutical Metal Detectors.
The ability for a conventional metal detector used in the food industry to detect metallic contaminants depends upon their conductivity and magnetic permeability:
If there are other types of contaminants (glass, calcified bone, ceramics, stone) to be detected, then an X-ray inspection system for food will offer enhanced detection capabilities.
All of these systems must be of a hygienic design specific to the particular type of food or beverage being inspected, and to suit the cleaning methods.
Alternatively and the most diligent is to consider the additional benefits of using an X-ray inspection system for food at this point.
Where should I put a food metal detector?
Metal detectors can be used throughout the food production process in order to protect consumers by detecting metallic contaminants and preventing the contaminated food from ending up on retailers’ shelves. With packed products, a food metal detector can be placed at the end of line for a final product inspection of metal contaminants.
Food metal detectors can also be used in line to protect other machinery that is downstream. A metal detector is normally installed before the machine to detect metal particles in order to help prevent damage to processing equipment, which can cause downtime and costly repairs.
