passing test cards through them every 15 minutes, Wybrow said. The company's first metal detec- tor, an Eriez unit installed 15 years ago, is still in use. Since then, the company has added an Eriez DSP detector to a bottling line and Phar - maceutical detector to its tabletting operation. The company plans to install two more Pharmaceutical detectors this year, and Wybrow said he hopes to eventually install an Xtreme metal detector, which is the newest model. How they work Eriez's metal detectors use three coils that surround the aperture through which products pass, and the center coil creates an electromagnetic field within that space. The other 30 March 2014 Tablets & Capsules Metal detectors help ensure product purity at Global Health Industries "You never know how clean the raw material will be when it comes in from our suppliers or if any small metal works its way into the processing end," said Kim Wybrow, Global Health's production maintenance supervisor. "Metal slivers can come off a stainless steel mixing vat or a capsule machine. Sometimes a screw or small washer falls off during the production process. These pieces are quite small and can be picked up by the metal detectors. Once the metal is detected, a light comes on and the product goes through the reject system. It does add another level of safety for our cus- tomers. It's very important to have equipment like the metal detectors on- site for final inspection of product before shipment." Workers verify that the detectors are working properly by The DSP metal detector, shown here installed on a bottling line, uses the same interface as the other Eriez metal detectors at Global Health Industries. "If you know one, you know the other, and that just makes it easier for everyone," said Kim Wybrow, the company's production maintenance supervisor. I N D U S T R Y a p p l i c a t i o n W h e n i t c o m e s t o p r o d u c i n g private-label vitamins and supple- ments for its network of distributors, Global Health Industries doesn't cut corners on quality-control measures. In fact, the family-owned business in Ogden, UT, has established numerous product safety checkpoints, from the raw-material receiving area to final packaging. That's important because Global Health performs all operations in- house, including R&D, formulation, manufacture, testing, and packaging. Products include multivitamins, herbal extracts, and drink mixes, which the company offers in capsules (gelatin and vegetarian, including pullulan), tablets, and/or powders. Packaging includes bottles, blisters, and sachets, all of which the company can shrink- wrap in bulk, pack, or box form based on the client's requirements. The com- pany's facility also holds a Certificate of Manufacturing from Australia's Therapeutic Goods Administration, one of the world's most active regula- tory agencies for dietary supplements. Metal detectors To help ensure quality, Global Health uses several metal detectors supplied by Eriez of Erie, PA, as well as an Eriez rare-earth magnet in the receiving area to remove ferrous cont- aminants from raw materials before they pass through a screener. g-IndApp_30-31_Masters 3/5/14 10:11 AM Page 30
