Abstract
An apparatus for separating usable crop from intermixed debris. The apparatus has: a) a conveying system configured to convey usable crop in a processing path from an upstream input location to a downstream output location; and b) a first separating system configured to cause separation of debris intermixed with usable crop as usable crop is conveyed in the processing path. A vacuum system downstream of the preliminary separating system is configured to: a) generate a low pressure volume which causes additional debris intermixed with usable crop to be drawn away from usable crop by vacuum; and b) cause drawn debris to be directed towards a collection location spaced from the output location while allowing usable crop to advance toward the output location.
