On–line detection of foreign bodies
In food manufacturing it is important to ensure that the product is free of contaminants. Metal detectors and x–ray systems are capable of on–line detection of many types of metallic object, and dense materials such as stones, glass and bone. However, material such as plastics, wood and fruit stones are difficult to detect with standard technologies.
The Food Radar system, reviewed in report RD412, uses microwave technology to detect and remove foreign bodies from pumpable food products such as jams, sauces and baby foods. Review of the Food Radar system for online detection of foreign bodies – RD412 can be found on the project web page
