Sesotec INTUITY metal detector put to the test by food manufacturers

Food manufacturers are faced with the challenge that products must be free of metals of all kinds, among other things so that the specifications of international quality standards such as IFS or BRC are met. The INTUITY metal detector from Sesotec sets the standard in metal detection here.

The multi-simultaneous frequency technology ensures product purity with up to 50% better detection accuracy than other systems on the market. No matter if the product is packaged or loose, frozen or thawed, the INTUITY metal detector can account for the interference caused by product effect to reliably detect metals. 

Designed for ergonomics and user-friendliness, this system offers an intuitive interface that includes simple operating logic and real-time imaging of the metal detection process. Guided sequences and predictions based on test pieces simplify the audit check. 

The performance of the INTUITY metal detector is compelling on its own. But when compared with devices from other manufacturers, the Sesotec system outshines the competition by achieving the best metal detection values.

Different customers, products and requirements - The metal detector INTUITY always delivers the best results

1. The metal detector INTUITY inspecting sausages

A family-owned company that has been on the market for over 70 years, with a focus on the production of cooked cured meats and boiled sausages is characterized by a high quality standard. Qualified employees, selected raw materials and the best machinery support these efforts.

The sausages are packed in commercial packages for the retail market. Metal detectors in the outgoing control of sausages in 1 kg packaging and a package size of 20 x 20 x 6.5 cm provide important information for quality management.

Result: Since sausages behave very differently depending on the orientation (longitudinal or transverse conveying), the metal detector´s multi-simultaneous frequency technology with system-supporting selection of the metal detection frequencies, offers the best performance.

2. The metal detector INTUITY inspecting mozzarella in block

A company that produces high-quality dairy products produces 5 - 10 kg of mo zzarella as a block for further processing in big industrial companies. Highest detection accuracy and avoidance of false triggering are the most important criteria for this customer.

Compared to devices from other manufacturers, Sesotec INTUITY metal detector has a competitive advantage when it comes to the best detection accuracy and the lowest possible false triggering.

Result: The customer is very satisfied with the INTUITY metal detector because of its performance in terms of detection accuracy, reliable product compensation and few false ejections. The loss of good products has been significantly minimized and the production has been running smoothly for a long time.

3. The metal detector INTUITY inspecting meat

A sausage maker does not accept any errors in terms of quality and that‘s why he uses only the best ingredients. To ensure the quality of the raw materials, incoming goods inspections are compulsory. This fulfills the requirements for compliance with the IFS standard and HACCP certification.

The metal detector INTUITY was able to convince in the incoming goods inspection for raw meat in E2 boxes because injection needles were reliably detected. Needles detection depends on how they pass through the metal detector. The large amounts of meat that fit in an E2 box (about 15 kg) make detection difficult as well.

Result: The metal detector INTUITY achieves the best detection results of needles even under difficult conditions, thus ensuring the quality of the sausages and the customer satisfaction.

4. The metal detector INTUITY inspecting ready meals

For almost 60 years, the catering specialist has been committed to proven quality. Strict monitoring is necessary so that only pure products are placed on the table of kindergarten children, students, seniors, hospital patients, company employees and others.

Metal detectors, which are used in the outgoing goods inspection for frozen ready meals in plastic packaging, should guarantee the desired sensitivity. Tests were made over a long period of time due to the influence of the thawing process of the frozen meals on the sensitivity. A clear differentiation between Sesotec and other manufacturers could be demonstrated in the thawed products. The achieved sensitivities with the metal detector INTUITY on thawed products almost corresponded to the results obtained with frozen products.

Result: The metal detector INTUITY exceeds customer expectations in all comparisons. The positive result in the tests always led to an order.


In the food industry, the detection of small metal parts is generally a big challenge. The so-called product effect, which depends on the salt or moisture content, the consistency of the product, temperature fluctuations, packaging material, orientation on the belt and size or shape of the product, has an influence on the performance of a metal detector. By actively reducing the influence of the product effect, the Sesotec INTUITY metal detector with multi-simultaneous frequency technology ensures product purity. An intuitive condition and the fair price complete the best offer for the food industry.

„THiNK“, the latest innovation from the Sesotec headquarters, is a metal detection system equipped with artificial intelligence. Sesotec‘s THiNK metal detectors for the food industry apply artificial intelligence in order to virtually eliminate the interference caused by product effect, even in the most difficult food products.
