Apparatus for the separation of tobacco lamina from tobacco stem

摘要

The modular pneumatic type tobacco separator has a separation chamber which receives a threshed tobacco mixture at a feed trough at an upper elevation, and receives an upwardly directed air stream at a lower elevation. The air stream separates the mixture into lamina material, which is blown upwardly and removed by way of a screening separator, and stem material which falls to the bottom of the chamber, and is removed by an upwardly inclined conveyor belt. The configuration of the separator is such that, when two units of the apparatus are placed interactively together, the stem material emergent from a first unit drops by gravity into the feed trough of the next successive downstream unit of the device.
