ABSTRACT:
Improved apparatus for grading and sorting of tobacco wherein the tobacco is dropped onto a continuously moving conveyor from which it is passed over an end plate and is scanned by one or more detectors suitably located in a housing mounted above the end plate, the detectors producing a signal indicative of the reflectivity of the desired tobacco leaf which signal controls an ejection system for separating the desired from the undesired leaf. The invention includes new structure for the end plate, detector housing and light source housing.
