  • Patent number: 7819123
    Abstract: An apparatus and method for the process of applying palladium salts to tobacco cut filler and other smokable products so that polycyclic aromatic hydrocarbons (PAHs) can be reduced in both mainstream (MS) and sidestream (SS) cigarette smoke. The reduction in PAHs is observed in the total particulate matter (TPM) of the mainstream (MS) and sidestream (SS) smoke. Additionally, substantial reductions in heavy metals and Ames biological activity can be achieved when the palladium salt solution is applied and processed in accordance with the present invention. The present invention provides these improvements by using a preferred ratio of palladium (Pd) salt to Chloride (Cl) that is specifically designed to allow for high palladium solubility. Further, the present invention provides an apparatus and method for applying the palladium salt solution while minimizing the number of processing steps required.

  • Publication number: 20080308115
    Abstract: A pouched, oral tobacco product includes a porous membrane, a loose tobacco material, and tobacco beads. The tobacco beads are formed from agglomerated tobacco fines and dust. The fines and dust are mixed with water, optionally a binder, and optionally flavorants to produce a wet mass that is extruded and spheronized to form tobacco beads. The tobacco beads are dispersed throughout loose tobacco material of desired size to form a material that is enclosed in a porous membrane.

  • Patent number: 4657144
    Abstract: A method and apparatus are provided for detecting and removing foreign material which may be found in a stream of particulate matter, such as tobacco. The tobacco is allowed to fall in a cascade past an optical detector. The turbulence of the falling motion brings a large proportion of the particles in the cascade into the field of view of the detector. When foreign material is detected, a signal is generated to activate a fluid blast directed at the portion of the cascade in which the foreign material is located.
