  • Process and apparatus for producing aromatized strand-shaped smoking material
    Patent number: 4995405
    Abstract: Aromatized liquid is introduced into the tobacco in the area of the settling path (AS) at a point at which nearly half the final tobacco layer has accumulated. Subsequently, the second half will settle thereon so that the inserted liquid is inside the final tobacco layer (15). Liquid is injected into the tobacco without the use of compressed air, thus excluding crystal formation. The injection rate of liquid is controlled responsive to the operating speed of the cigarette making machine.
