Ferromagnetics- permissible presence of them sugar, if so, what is limit( what is the standard)

[Eric G]

Hello Alutka_120, 

 

Generally sugar is free from product effect from a metal detectors perspective, so the detectable size of any metal within the product will be mainly limited by the size of aperture that can be used. Smaller apertures will be more sensitive.  If inline running though a gravity style metal detector, on lets say 150mm scanning pipe, you are probably detecting down to 0.8-1.0mm Ferrous quite easily.  In a 25kg bag around 1.5mm.  (detected in the center of the aperture where the metal detector is the weakest)

 

Best practice is to use the smallest possible aperture size for the product you're inspecting.  Depending on your customer requirement, they may stipulate a performance you must meet.  Otherwise it may be acceptable to validate the system to see what is the smallest size that is reliably detectable with your equipment. 

 

Regards,

Eric

Thank you for your response


So there are no established limits in EU laws?

and if sugar is imported from countries outside the EU like Ukraine?

1, If it is pure white sugar, it does not have product effect and can reach the maximum sensitivity of MD itself.

2, This should not be an MD issue, but an independent food standard issue.

Therefore, you may need to consider how to select the appropriate MD to adapt to food safety standards as much as possible. This is what Eric said.

3, MD can't directly confirm that your products must meet food safety standards. It is just a quality control method.

And users need to pay attention to some failures of MD, such as metal wire, metal oxide, etc.
