"We're trying to take these systems to the next step with software that not only can detect contaminants but also perform quality control functions, such as detect missing pieces," notes Erik Brainard, X-ray product manager at Loma Systems Inc., Carol Stream, Ill. "A lot of consumer complaints have to do with under counts, for example." Packers of specialty candies are seen as prime candidates for such systems, he adds.
All the major metal detection firms have come out with X-ray units in recent years. Early adapters of the technology have primarily been European firms, though U.S. baby food manufacturers and others are experimenting with X-ray units
