Mettler Toledo X39 X-ray Inspection System conducts ten product integrity checks in one inspection pass
The X39 X-ray inspection system designed by Mettler-Toledo Safeline now enables manufacturers of frozen formed burger patties (beef, pork, chicken, fish and vegetarian) to detect and reject non-conforming products, including both those containing contaminants and those with other product irregularities or defects. The X39 employs a two-stage inspection process. Stage one is an integrated laser technology preliminary brand integrity check for flake defects, and length, width and height irregularities. (Flakes are small pieces of uncooked product that can land on a patty during the forming process, before the entire product is frozen. There is a risk that the underside of the flake will not be 100 percent cooked.) This inspection takes place regardless of product position. A single bank of air nozzles and a reject flap immediately removes any substandard products from the conveyor.
In the second inspection stage, the X39 X-ray detector consecutively inspects the remaining good products for foreign-body contaminants, such as calcified bone, mineral, stone, glass, metal and absorptive plastic, and additional product defects, including holes, dents, edge deformities, mass and shape. Air nozzles reject substandard products into a secondary rework receptacle, further minimizing waste, ensuring brand integrity and upholding food safety requirements.
