Abstract: A foreign substance eliminating apparatus transfers raw material by passing the raw material between an upstream conveyor (6) and a downstream conveyor (8), and detects a foreign substance on the upstream transfer conveyor with a foreign substance detector (9). An eliminating airflow (R) is ejected from a row of air nozzles (13) when the detected foreign substance falls down, and deflects the falling direction of the foreign substance.
