Why are METAL DETECTORS used in the food industry?
Consumer and brand protection are the main reasons why metal detectors are used in the food industry. In addition, certain food industry standards, such as IFS, require a well-established process for detecting contaminants. Metal detectors will provide effective protection against metal contaminants and therefore compliance with the standard.
IFS Food, the international standard for food quality and safety, allows the evaluation of food quality and safety management systems in a unified approach.
IFS Food is a standard for auditing suppliers that manufacture food under their own brand, retail chains, and wholesale and other food manufacturers and only applies to food companies or those who pack bulk food.
The new IFS7 standard, which will apply to start on 1st of July 2021, specifies the elimination of the risk of contamination of products in HACCP points, so metal detection solutions or X-ray systems become mandatory for the management of this risk.
Even if, during the production process, the greatest care is kept to eliminate any possible foreign bodies, the metal contaminants cannot be completely excluded. From the fact that these metal particles can be contained in the raw material or that certain metal contaminants can come off the equipment, every precaution must be taken that these particles do not reach the final product and do not cause serious damage to consumers. It is known that any inconvenience caused to the consumer can trigger the loss of customer trust, a negative image of the brand, and can turn into expensive claims and returns.
Metal food detectors are those that provide effective protection against metallic, ferrous, and non-ferrous contaminants (aluminum, stainless steel, etc.) for various applications and products, such as inspection of liquid or viscous products (dairy, jam, etc.), meat, and sausages, in the bakery industry for the inspection of bread and other products, for the inspection of fruits, vegetables but also of free-falling products such as rice, spices, sugar, etc.
Imark Sistem is the exclusive partner for Romania of CEIA, a world-renowned company in the field of metal detectors, a top supplier with more than 50 years of experience on the market. CEIA metal detectors identify metallic contaminants accidentally present in food and non-food products, with levels of sensitivity, immunity to interference, and response speeds that exceed the strictest quality control standards.
Where should metal detectors be installed in the food production process?
Because consumer protection is the main objective of inspection in the food industry, it is useful to use metal detectors at several points.
The inspection of the raw material has the advantage of detecting the metal particles before they are transformed into smaller pieces as a result of the processing processes, which would make them otherwise even more difficult to detect.
In addition, these raw materials can damage the knives of the processing equipment if not detected in time.
Complete exclusion of contamination involves inspection of the final product, after packaging, with a metal detector (or an X-ray detection system).
In conclusion, for optimal protection of the product, the inspection of the raw materials and a final inspection of the finished, packaged product is recommended.
CEIA THS 21 metal detection systems offer detection, construction quality, and reliability features that make them the most suitable and efficient solution for the automatic detection of metal contaminants.
What is the technology used by CEIA for metal detectors?
CEIA’s approach in developing its detectors was to use the most advanced electronic and mechanical technologies: Surface Mount Technology (SMT), digital signal analysis, software updating capability, and the use of high-quality materials for equipments.
According to HACCP and GMP, CEIA metal detectors are ISO 9001 certified and made of CE and FDA-approved materials.
CEIA metal detectors equipped with innovative MultiSpectrum technology automatically select and use at the same time an adapted range of detection frequencies suitable for both the product and its packaging, for a maximum compensation of the interferences created by the product and packaging. This allows, under certain conditions, the detection of metals for difficult products and/or products packaged in metallic foil and offers the best level of detection compared to other equipment on the market.
CEIA’s range of metal detectors covers a wide range of applications: raw materials, packaged products, free-falling products (rice, sugar, condiments, etc.), liquid or viscous products (jam, dairy products, etc.)
