Potato chip producer upgrades metal detection
When Hostess Frito-Lay wanted to increase the sensitivity of its metal detectors, the company switched from units that inspected cases of bagged chips to more sensitive units that inspect the chips before they're bagged.
Hostess Frito-Lay's plant in Cambridge, Ontario, produces potato chips, some of which are fed by vibratory systems to form-fill-seal [FFS] machines that package 200 or 300 grams of the chips in metallized bags. A mechanical conveyor at each machine then moves the bags from the FFS machine for packaging into cases that go to the company's customers.
