ABSTRACT:
A grain separator to separate and remove contaminants such as dust and debris from grain including an intermediate separator housing having a grain inlet port to receive grain to be scoured from an external source, a grain outlet port to feed scoured grain to an external collector, a first containments discharge port to discharge heavier contaminants removed from the grain to a first external receptacle and a second contaminants discharge port to discharge lighter contaminants removed from the grain to a second external receptacle, a mechanical separator and transport assembly operatively disposed within the intermediate separator housing to receive the grain and contaminants from the grain inlet port to separate the contaminants from the grain and to move the grain from the grain inlet port to the grain outlet port for collection in the external collector, a first containments transport assembly disposed to receive the heavier contaminants from the mechanical separator and transport assembly and to move the heavier contaminants to the first containments discharge port for collection in the first external receptacle and a second containments transport assembly disposed to receive the lighter contaminants from the mechanical separator and transport assembly and to move the lighter contaminants to the second containments discharge port for collection in the second external receptacle.
