摘要： Tobacco is treated to cause its expansion by a process which comprises the steps of subjecting it to a reduced pressure of not greater than 7 kPa, impregnating the cell structure of the tobacco with isopentane vapour at temperatures of 70 to 90 °C and maintaining the tobacco in contact with the vapour at a pressure of at least 400 kPa for up to 30 minutes, evacuating the excess vapour, the pressure change being effected adiabatically, treating the impregnated tobacco with steam to expand the tobacco cell structure and then subjecting the expanded tobacco to vacuum reordering. Expansion levels achieved by the process are similar to and may be greater than those achieved using conventional expansion processes.

摘要： Methods of reducing the content of and preventing formation of carcinogenic nitrosamines in harvested leafy plants such as tobacco and marijuana are disclosed. The methods are directed to subjecting the plant to microwave and/or higher frequency radiation, at appropriate times in the cure cycle. With tobacco, products suitable for human consumption, such as cigarettes, cigars, etc., can be made in accordance with the present invention, having contents of tobacco-specific nitrosamines on a par with fresh-cut, green tocacco. In preferred embodiments, the resultant tobacco products are dried, golden-yellow leaves having almost negligible amounts of the known carcinogens NNN and NNK, in comparison to conventionally cured tobacco.

摘要： Disclosed is a method of producing an expanded tobacco material. According to the method, a tobacco material (TM) is fed into a pressure vessel, (11), followed by pressurizing the interior of the pressure vessel (11) with a carbon dioxide gas to a predetermined impregnation pressure. Then, a liquid carbon dioxide (21) is supplied from above the tobacco material (TM) into the pressure vessel through a sintered metal plate (13), etc., while maintaining the impregnation pressure, thereby saturating the interior of the pressure vessel (11) with a carbon dioxide gas generated by vaporization of the supplied liquid carbon dioxide, and cooling the tobacco material by the latent heat of vaporization of the liquid carbon dioxide, so as to impregnate the tobacco material with carbon dioxide. The tobacco material impregnated with carbon dioxide is brought into contact with a hot gaseous stream within a gaseous stream dryer so as to expand the tobacco material.

摘要： Die Erfindung betrifft eine Fördervorrichtung zum Erzeugen einer Tabakmonolage, deren weitgehend vereinzelten Tabakteile einer speziellen Weiterbehandlung, wie der Fremdkörpererkennung und -ausscheidung unterzogen werden können.
Es ist das Ziel, auf einem Fördermittel ein einlagiges, geschlossenes Tabakvlies zu bilden.
Erreicht wird dies durch aufeinanderfolgende, in Förderrichtung (2) mit steigender Geschwindigkeit betriebene Fördermittel (4, 7), von denen das stromabwärtige, schnellerlaufende Fördermittel (7) aus zwei übereinanderliegenden Förderbändern (8, 9) besteht, die einen Förderkanal (11) bilden, und das stromaufwärtige Fördermittel (4) als Schwingförderer (6) ausgebildet ist, der eine profilierte Abwurfkante (24) aufweist.
Mit Hilfe einer derartigen Anordnung und Ausgestaltung der Fördermittel läßt sich bei hoher Förderleistung eine weitgehend vergleichmäßigte bzw. lückenlose Tabakmonolage erzeugen.

摘要： A rotary tobacco treatment cylinder comprises an elongate hollow cylinder arranged to rotate about its longitudinal axis and disposed substantially horizontally or inclined by a small angle (α) to the horizontal, a series of elongate paddles extending longitudinally within the cylinder and extending generally towards the longitudinal axis from the inside surface of the cylinder, said paddles serving to convey material to be treated from a lower position within the conveyor and around one side to an upper discharge position. Each of said paddles has a proximal portion (20) extending at a first angle being a right angle to the tangent at the root of said proximal portion or an angle less than a right angle at the loaded side of the paddle, and a distal portion (22) which is inclined to the proximal portion at a second angle, which is less than the first angle, to form a tip. A major part of the tip considered longitudinally is of a length (viewed axially of the cylinder) less than half the length of the proximal portion. The angle (β) of the tip of each paddle to the tangent at the root of the proximal portion is such that at a predetermined release point the tip is at the angle of sliding (S), the surface of the tobacco charge just contained by the tip being at the angle of repose (R).

摘要： A tobacco expansion method is provided whereby cured tobacco is first moistened with a humectant solution, as is conventional in the industry, to increase the resident liquids thereof. Next, the prepared tobacco in shredded form is placed in a sealed chamber and the chamber evacuated to vaporize a portion of the resident liquids. Next, ethyl alcohol vapor is allowed to enter the pressure chamber below 70 mm (Hg) absolute to prevent a water-ethyl alcohol azeotrope from forming. Thereafter, a hydrocarbon vapor, such as n-pentane vapor, is directed into the chamber and the pressure restored to atmospheric. The n-pentane vapor diffuses into the cellular structure of the tobacco with the assistance of the ethyl alcohol, whereafter the tobacco is heated and the n-pentane and ethyl alcohol acts as a propellant to expand the tobacco.
