An apparatus and method for post-threshing inspection and sorting of tobacco lamina is described and which includes a separation conduit which receives a source of post-threshed tobacco lamina and other contaminants for inspection and sorting, and wherein a source of pressurized air causes the tobacco lamina to move along the separation conduit past an inspection station where it is optically inspected to identify undesirable tobacco lamina or other contaminants; and a downstream reject station is provided which responds to a sorting signal provided by the inspection station and which removes unwanted or undesirable tobacco lamina and other contaminants from an air stream so as to provide a resulting product which is substantially free from contaminants or other defects.
