Metal Detectors Help Mariani Packing Company Deliver Contaminant-Free Dried Fruit Snacks

Problem
To remain competitive in the demanding and highly-scrutinized food industry, Mariani Packing Company has established critical control points (CCP) throughout its five processing facilities, one of which is located in Wisconsin Rapids, WI. Mariani needs double protection against any sort of metal particulate that might be found in loose and packaged dried cranberries before reaching customers. More than 27,000 grocery stores in the U.S. sell Mariani dried fruits.

Solution
Part of the CCP involves the use of two Eriez Xtreme Metal Detectors positioned along different stages of the processing line which detect metal contamination in loose and packaged cranberries, according to Director of Operations Jesse Urban. Mariani installed one unit with a 24” wide x 3” high aperture opening for loose cranberries and another Xtreme with a 20” wide x 12” high aperture opening for packaged cranberries. “We were able to send samples of dried cranberries back to the Eriez test lab. When we received the metal detectors, they were already pre-loaded with the cranberry settings. We were able to set up the metal detectors out of the box with a few minor adjustments,” Urban says.

Result
“The metal detectors have always been spot on. We’re running large volumes of loose cranberries per day through the first metal detector and bulk cases of packaged cranberries through the second detector,” Urban says. Another reason Mariani purchased the Xtreme Metal Detector was the low rate of false triggers, according to Urban. “We get very dry winters here in Wisconsin, so static electricity is a problem,” he says. “Eriez worked with us to modify the metal detectors so they are not as affected the static in the plant. And in the summer, it gets really humid and that also punishes the equipment. It’s good to see a company like Eriez could eliminate our problems.”
