Most common uses for metal detectors in bread factories

Bread has been made for thousands of years.  The process hasn’t changed much over time other than the efficiency of making it.  Today’s modern bread (bakery) companies bake an astounding number of loaves.  If you’ve ever been in a bread factory you’ll first notice the precision and solider like appearance of the operation.  One area that is critical for both consumers and machinery alike is the removal of metal contamination.

Where to install metal detectors in bread lines?

The most common place to install a metal detector, such as the Goring Kerr DSP 3, is at or near the end of the line.  You will often see the metal detector placed just before the slicer and wrapping machines.  Why?  It’s believed that since this is the very last place metal could be introduced it must be the best place to install a detector.  In fact this is not the most effective place to install one.  As with any production line the end on the line is where you have spent the majority of money to manufacture the goods.  So why would you want to through it away!  As a safety net I would suggest installing a metal detector at this location however, I would also install several others to be sure.

Reduce the cost of waste product

A great way to reduce costs in production and maximize the safety of removing metal contaminates is to place several metal detection system within the line.  First, start with the raw ingredients.  At this point your cost per reject is lowest as well you can use this data to grade or score your suppliers.  The more metal the lower cost you should pay.  The next location is just prior to the oven.  The dough balls are another good location to place a metal detector.  Finally, the last system should be placed just before the slicer.  Ideally it would be nice to have it after the slicer since metal could enter here but slice bread is extremely tough for this type of equipment.

If you have a metal detector on your bread line make sure you have it running at optimal performance.  Head over to the Goring Kerr manuals and make sure you’re following all the correct installation requirements.



Goring Kerr founded the industrial metal detector back in the early 1900's. Since then they have engineered a wide range of metal detectors used throughout the world. Well known for their food metal detectors Goring Kerr can be found in bakery, pharmaceutical, lumber, plastic, textile and grain applications. Through the years they have manufactured models including the DSP 3, DSP 2, DSP 1, Tek 21 and Tektamet to name a few. Still today you will find Goring Kerr metal detectors 40 years old operating and detecting metal as well as many of today's new machines.
