A METHOD AND AN APPARATUS FOR IDENTIFYING FOREIGN BODIES IN PACKAGED BEVERAGES, AS WELL AS USE OF THE APPARATUS

摘要

A method and an apparatus (10; 31) for identification of foreign bodies (4) in packaged beverages, where the package (1; 12; 30) and the beverage are translucent and the foreign bodies (4) have a density greater than that of the beverage. The method is unique in that the package (1; 12; 30) is oriented in a first position in which the foreign bodies (4) are collected on an internal, upwardly directed face (5) in the package (1; 12; 30), and that the package (1; 12; 30) is then turned to at least one subsequent inclined position having an inclination sufficient for the foreign bodies (4) to perform a downward movement along said face (5). During this movement, at least one of the foreign bodies (4) is identified by comparing at least two successive position-determining detections. This provides a method and an apparatus (10; 31) for certain identification of foreign bodies (4) in dark as well as light beverages and in disposable as well as recyclable packages (1; 12; 30).
