Inspection & Detection: Looking for Trouble

One of the major challenges for bakery producers today, when it comes to food safety and inspection technologies, is not so much about the products themselves, but about their packaging.

Recent technological advancements include product clustering on metal detection systems, which allows multiple product types to be “clustered” and be inspected on one common setting. For example, different types of bread loaves (white, brown, cheese, etc.) can be inspected together. As a result, product clustering reduces the need for product changeovers, which even in the most modern plant bakery can be frequent and potentially time-consuming.

Vicky Myers, product inspection specialist at Mettler-Toledo described some of their solutions for European Baker & Biscuit magazine: “Metal detectors such as the Profile Advantage from Mettler-Toledo have been developed with technology to virtually eliminate the occurrence of false rejections. They use a combination of high and low frequencies simultaneously along with product signal suppression technology to effectively remove the product signal from hot or cold products such as baked bread. The varying product characteristics of hot food often results in ‘good’ product being falsely rejected due to a phenomenon called ‘product effect’, which creates an electrical signal that can cause unwanted false readings. This can lead to lost production time and wasted money. The Profile Advantage’s technology virtually eliminates these false readings to significantly reduce false rejects and wasted product.”

The detection of foreign bodies must be extremely precise in order to ensure consumer safety. Non-detected foreign bodies can lead to costly recalls of products, which go along with a negative impact on manufacturers’ brand reputation.

Peter Taggenbrock, global product manager at Minebea Intec says that modularity is also a way to easily adapt to changing production needs.

One solution that Minebea Intec offers for this task is Combics – a series of verifiable industrial bench scales that can be tailored to the required maximum capacities and resolutions.

“The Combics series also offers a special single-workstation solution for the pre-packaging checking of bakery goods, which is particularly useful in smaller-scale production processes. Automatic statistics and printouts, as well as graphical evaluations on the scale display, help users with their day-to-day tasks,” explains Lars-Henrik Bierwirth, product manager, software solutions, Minebea Intec.
