AUTOMATIC DETECTION OF FOREIGN MATTER IN FOOD Available to Purchase

Detection of foreign matter is difficult due to its very nature, but this needs to be developed to reduce the effects of sabotage, to protect reputations, and for safety reasons. Most methods of automatic detection depend on the density and opacity of the matter and are thus not successful in all cases. Methods such as filtration and screening, metal detecting, rejection, search heads, and sensitivity measures have been improved in recent years. It is stressed that all detectors must be hygienic with regular maintenance to eliminate problems of care and cleanliness.
