Abstract
A tobacco expansion apparatus and method comprising a source of tower gas, an obloid transfer duct, in communication with the gas source, a tobacco feeder at a location along the obloid transport duct and a separator for recovering tobacco from the expansion apparatus. The tobacco feeder is adapted to introduce tobacco uniformly across the width of the obloid transfer duct. The apparatus improves the filling power of the processed tobacco and can be operated at higher production rates with less tobacco breakage, thereby improving tobacco yield.
