Abstract
A foreign object separation apparatus which utilizes a camera which views a flow of material being conveyed in order to develop an electronic control signal indicative of the presence of foreign matter within one or more main or overlapping zones which are monitored across the flow of material to thereby control valves which actuate appropriate individual or adjacent fluid nozzles to expel the foreign matter from the material being conveyed.
