Foreign substance eliminating apparatus

A foreign substance eliminating apparatus comprising:

• an upstream transfer path for transferring raw material;
• a downstream transfer path located down below said upstream transfer path, for receiving and transferring the raw material falling down from being sent out of a terminus of said upstream transfer path;
• detecting means for detecting a foreign substance from the raw materials being transferred on said upstream transfer path, and for outputting a detection signal;
• deflecting means for deflecting the falling direction of the falling raw material and the foreign substance by ejecting an eliminating airflow towards the falling raw material, on reaching a decision of the existence of the foreign substance within the raw material, based on said detection signal;
• capturing means for capturing the foreign substance passing through the eliminating airflow and falling down, above said downstream transfer path;
• and
• eliminating means for removing the foreign substance captured by said capturing means, to the outside of said downstream transfer path.
