Automatic Metal Detector for Packaged Grain Food Bag Box Inline Metal Detector
This automatic metal detector for packaged grain is specifically designed for packaged goods, enabling continuous inspection as items—such as bags, cartons, boxes, and other containers—move along the conveyor belt. Food bag box inline metal detector identifies common ferrous, non-ferrous, and stainless steel contaminants, detecting foreign objects that might otherwise remain hidden inside the finished packaging. Upon detection, an automatic rejection mechanism removes the contaminated package from the production line. Any OEM and customer design orders are welcome!
