In flowing products
Contamination by foreign matter is a problem particularly in the food production and pharmaceutical industries. The safety of consumers is of top priority, but economic damage caused to producers by product recalls or new productions can also be significant.
Machines and equipment can be badly damaged in particular by metallic foreign matter.
Therefore, magnetic filtration of metallic residues in, for example, sugar, spices, and processed or unprocessed grain is an important part of the production chain.
