Abstract
Winnowing of shredded tobacco stem material, or other particulate tobacco material, is effected by metering the shredded stem material from a reservoir and then picking the metered flow to open and separate the particles one from another. The resulting stream of separated individual particles of shredded tobacco stem material is projected into an upwardly-flowing air stream to entrain a desired lighter fraction of the particles and carry it out of the separator device. The undesired heavy fraction falls in the separator device and is collected. The collected heavy fraction preferably is reprocessed to separate agglomerates of shredded stem material present in the heavy fraction into individual particles, which are then entrained in a second upwardly-flowing air stream which subsequently joins up with the first gas stream.
