    Abstract: A personal vapor inhaling unit is disclosed. An electronic flameless vapor inhaler unit that may simulate a cigarette has a cavity that receives a cartridge in the distal end of the inhaler unit. The cartridge brings a substance to be vaporized in contact with a wick. When the unit is activated, and the user provides suction, the substance to be vaporized is drawn out of the cartridge, through the wick, and is atomized by the wick into a cavity containing a heating element. The heating element vaporizes the atomized substance. The vapors then continue to be pulled by the user through a mouthpiece and mouthpiece cover where they may be inhaled.

  • Patent number: 8534297
    Abstract: The present invention provides a method of testing moisture retention of tobacco in which dynamic rules on moisture desorption of the cut tobacco in a dry environment are investigated by using a dynamic vapor sorption system and has found that a dry basis moisture content at an earlier stage of moisture desorption of the cut tobacco has a preferred linear correlation with a square root of time. A linear fitting for t0.5 is made by using values of a dry basis moisture content Mt at a time point t, and a rate constant k is obtained from a slop of the obtained straight line and used as a reference of testing the moisture retention of tobacco. The method can also be used to investigate the moisture retention of tobacco and filter humectants of cigarettes. In comparison with the conventional method, the method is convenient and applicable, and has a short testing period, a high degree of automation, preferred accuracy and preferred reproducibility, etc.

    Abstract: Encapsulated tobacco beads and processes of making the encapsulated tobacco beads are disclosed. According to an embodiment, a process of making encapsulated tobacco beads comprises mixing tobacco particles and menthol in an aqueous solution to form a wet mass; extruding the wet mass to form extrudates; spheronizing the extrudates to form tobacco beads; drying the tobacco beads; contacting the beads with a solution comprising a cation; and introducing the contacted tobacco beads into a solution of coating material in a concentration effective to induce ionic gelation of the coating material around the beads, to form encapsulated tobacco beads having gel coatings. According to another embodiment, an encapsulated tobacco bead comprises a core comprising tobacco particles and encapsulated menthol, an inner coating layer comprising hydroxypropyl methylcellulose or pectin, and an outer coating layer comprising an ionically-crosslinked gel.

  • Patent number: 8020566
    Abstract: A dispenser for dispensing a metered amount of liquid into a porous plug includes a casing which has an inlet passage adapted to receive a manually insertable porous plug. A reservoir disposed in the cavity contains the liquid. The reservoir has an outlet which is communicable with the inlet passage. A discharge mechanism disposed in the casing is actuable in response to the insertion of a porous plug into the inlet passage for producing a pressurized air flow which bears against a piston in the reservoir for discharging a metered amount of the liquid from the reservoir into the porous plug. The plug could constitute a filter attached to a tobacco column.

  • Patent number: 7946295
    Abstract: The invention provides a process for preparing a tobacco composition suitable for use as a smokeless tobacco composition, including: providing a moist tobacco material; heating the moist tobacco to a temperature of at least about 85° C. for a time sufficient to pasteurize the tobacco material while maintaining the moisture content at a relatively constant level; adding an amount of a base and water to the moist tobacco material sufficient to raise the pH of the slurry to at least about 8.7 and raise the moisture content to at least about 40% by weight, thereby forming a pH-adjusted moist tobacco material; and continuing to heat the pH-adjusted moist tobacco material to a temperature of at least about 55° C. for a time sufficient for the pH of the moist tobacco material to drop to less than about 8.5 while maintaining the moisture content at a relatively constant level.

  • Publication number: 20100059076
    Abstract: A present invention provides a method for reducing harmful substances and carcinogenic substances contained in a tobacco leaf. According to the present invention, the harmful substances and the carcinogenic substances are removed beforehand by washing a shredded leaf with a solvent, so that the tobacco leaf having a small amount of the harmful substances and the carcinogenic substances contained therein is produced. The cigarette produced by such a method of the present invention reduces an amount of the harmful substances and an amount of the carcinogenic substances contained in primary smoke and second-hand smoke in a case of the tobacco smoking, and reduces an amount of the harmful substances and an amount of the carcinogenic substances to be taken into a body compared with a cigarette produced in a conventional manner.
