■ Product Overview
Food Metal Detector is a machine used in food production lines to detect and remove metal contaminants such as iron, stainless steel, and non-ferrous metals.When products are inspected in real time, the system will automatically trigger the rejection device to remove the defective products from the production line if products containing metal impurities are detected.
