Abstract
A method for sorting out interfering objects (2) in a material stream (13) consisting of acceptable material (1), preferably cullet, wherein during a sorting process the interfering objects (2) and the acceptable material (1) are respectively sorted in at least one separate room area or container, preferably a shaft (9, 10). In order to achieve high degrees of purity with low loss of acceptable material and to simultaneously avoid the use of high fluid blowout pressures and quantities, it is provided that the material stream (13) is continuously subjected during a sorting process to a fluid stream, preferably consisting of compressed air, having a blowing pressure, wherein the fluid stream is interrupted temporally and/or locally depending on a detection result of a detection device (14), which detects the interfering objects in the material stream (13).
