ABSTRACT:
The particles of a continuous tobacco stream are conditioned during transport through a vibratory conveyor having a bottom wall located above a stationary chamber which receives conditioned air from one or more blowers. The bottom wall is formed with apertures through which the air passes across the tobacco stream in the form of pulsating currents which agitate the particles of the stream to insure a pronounced energy exchange between tobacco particles and air. The currents pulsate due to vibration of the bottom wall relative to the chamber, and the latter is provided with transversely extending baffles which insure that the tobacco stream is traversed by air currents having different intensities. The same result can be achieved by forming the bottom wall with larger and smaller apertures. The vibratory conveyor has two sections in the first of which the particles of tobacco are contracted by air having a temperature and moisture content corresponding to the desired temperature and moisture content of conditioned tobacco. The air which has been used for heating of tobacco in the first conveyor section is intercepted and is thereupon conditioned prior to admission into the second conveyor section.
