Compact, flexible and reliable: product inspection that allows you to enjoy sweets safely


Sweets manufacturer SAILA wanted to add a metal detector to its existing production system. The inspection solution had to be able to identify different kinds of foreign objects in a reliable way, without taking up a large amount of space. 


SAILA, which stands for Italian Liquorice Corporation of Abruzzo (Società Anonima Italiana Liquirizia Abruzzese), is an Italian food company founded in 1937 in Silvi Marina. The historic factory is therefore over 80 years old, and continues to keep alive the love the province of Teramo has long held for liquorice. SAILA carries out a process first adopted by Dominican monks back in the 16th century, but on an industrial scale. The renowned manufacturer of liquorice sweets added mint-based sweets to its production lines in 1950, and began selling them in their traditional bags in 1964. The SAILA brand was a trailblazer once again in 1978, when it launched its boxed sweets.


Project goal and implementation 

In order to ensure high quality standards in the earliest production stages, SAILA decided to use a metal detector immediately after the compressor stage, and well before the final packaging of the product. This is where Minebea Intec came in, creating a compact solution for inspecting the loose sweets. The adopted solution has enabled reliable checks and secure detection of metal contaminants inside the sweets. 

However this was only the beginning. SAILA put their trust in Minebea Intec to provide other control and inspection solutions along the entire production line at the factory in Silvi Marina, in order to guarantee the production process to its very end. In fact, several checkweigher CoSynus® combined model groups (check- weigher and metal detector) are installed in the factory for checking the packaging and ensuring that pre-packaged products conform with Italian Law 690. These weighing machines are then connected to the SPC@Enterprise soft- ware, which enables real-time production checks, minimising downtime and improving production performance. 


The checkweigher CoSynus® ensures safe and reliable weighing and metal-detection checks. It takes up minimal space on the production line.


In addition, a final check is also carried out using a checkweigher Essentus®. This ensures that no package leaves the SAILA factory with a box of sweets missing.


The checkweigher Essentus® ensures that all boxes are filled with right amount of packs.


Key facts 

The new metal detector was to be added to an existing production line and needed to be able to identify the tiniest metal contaminants in the early stages of production, in order to guarantee the high quality of the company’s product. To achieve this, the new metal-detection solution was introduced immediately after the compressor. 



After coming out of the compressor, the loose sweets are passed through the metal detector, which has a very small opening for detecting the smallest contaminants.
