An additional benefit of the dual beam X-Ray System is it offers zone detection as packaged or raw product moves through the unit, according to Spurgeon. Rather than rejecting an entire row of product, the X-Ray unit will pinpoint a single product with a foreign object for precise rejection, thus allowing noncontaminated product to proceed. “This will save our customers thousands of dollars in re-work and labor,” says Spurgeon. Moreover, Eriez X-Ray Systems operate using very low beam energy because of the company’s unique beam architecture. This design places Eriez’ X-Ray source very close to the belt/product and thus, the lowest energy. “Conversely, other manufacturers’ systems require more energy, as the x-ray sources need to be higher up from the belt/product. This can cause burn through of the foreign object,” says Spurgeon. The dual beam technology also provides coverage for a conveyor belt more than 40 inches wide. Traditional X-Ray systems have accommodated belts up to 24 inches, according to Spurgeon. The sheer size of the dual beam coverage is unique to the industry as well as the use of individual zones with dedicated rejects for each. The Eriez E-Z Tec DSP Metal Detector complements the dual beam X-Ray system by detecting ferrous, nonferrous, stainless steel and aluminium objects in package and raw product. The standard three-coil aperture arrangement sends a signal to the unit’s control for digital processing. According to Spurgeon, the E-Z Tec X-Ray system and E-Z Tec DSP Metal Detector can be monitored and controlled remotely by using Eriez E-Z Link™ software.

DuPont Qualicon Releases New BAX® System Test for E. coli O157:H7
eef processors, service labs and other food industries can now use a new test from DuPont Qualicon to quickly and accurately check beef and produce for contamination with E. coli O157:H7. Developed in collaboration with the USDA Agricultural Research Service, this BAX® System assay uses realtime polymerase chain reaction (PCR) technology to quickly detect all known E. coli O157:H7, even atypical strains that can be missed by some other tests. E. coli O157:H7 is a foodborne pathogen that can cause serious, sometimes fatal, illness at very low infectious doses–as few as 10 organisms. The BAX® System realtime assay was validated on industry standard sizes of ground beef, beef trim, lettuce and spinach that were spiked at 1–2 cells per portion, and it was found to perform as well or better than the reference culture methods. According to Dr. Frank Burns, senior scientist at DuPont Qualicon, E. coli O157:H7 is a highly complex and variable organism that can be challenging to detect at low

Eriez® Introduces Extra Wide Combination DualBeam Multi-Zone X-Ray and Metal Detector System
riez® has introduced an extra wide combination E-Z Tec® DualBeam Multi-Zone X-Ray and Metal Detector System. This state-of-theart device offers optimal detection and precise rejection of virtually any foreign object for packaged or bulk flow applications. “Working together, the X-Ray will provide Eriez customers with unsurpassed foreign objects detection for ferrous, nonferrous, stainless steel and non-metallics such as stone, glass, bone and some plastics. Additionally, the metal detector will provide for the best possible detection for aluminum–which is the most difficult metal for the X-Ray machine to detect,” explains Ray Spurgeon, Eriez product manager–Inspection Systems. “Now, processors can use both technologies to improve their food safety,” he says.
