Patent number: 6125855Abstract: Tobacco is treated to cause its expansion by a process which comprises the steps of subjecting it, in a treatment chamber, to a reduced pressure of not greater than 7 kPa, impregnating the cell structure of the tobacco with isopentane vapour at a temperature in the range of from 70.degree. C. to 100.degree. C. and maintaining the tobacco in contact with the vapour at a pressure of at least 400 kPa, removing excess isopentane vapour from the treatment chamber, contacting the impregnated tobacco with steam to expand the tobacco cell structure, reducing the pressure in the treatment chamber at a rate of at lest 10 kPa/minute, preferably 30 kPa/minute, and then venting the treatment chamber back to atmospheric pressure. The final filling value of the tobacco treated according to this process is directly proportional to the rate at which the pressure in the treatment chamber is reduced following the steam treatment of the tobacco.Type: GrantFiled: October 20, 1998Date of Patent: October 3, 2000Assignee: Imperial Tobacco LimitedInventors: Robert Nevett, Clifford Hendrik Henneveld, Keith Alan Matthews, Brian Chester Chard

Patent number: 5235992Abstract: Processes for producing flavor substances from tobacco are disclosed. The processes involve heating tobacco during a first staged heating to a first toasting temperature to drive off volatile materials; increasing the toasting temperature during a second staged heating to a second toasting temperature and separately collecting, as flavor substances, at least portions of the volatile materials driven off at the first and second toasting temperatures.Another aspect of the present invention involves reducing the moisture content of the tobacco without removing volatile flavor components, such as by freeze drying the tobacco, and then heating the dried tobacco.Preferably the tobacco is heated in a flowing gas stream and at least portions of the volatile materials are separately collected as flavor substances as the gas stream passes sequentially through a moderate temperature trap, a cold temperature trap and a filter capable of collecting submicron sized particles.Type: GrantFiled: November 27, 1991Date of Patent: August 17, 1993Assignee: R. J. Reynolds Tobacco CompanyInventor: Andrew J. Sensabaugh, Jr.

Patent number: 4665931Abstract: In order to pest control tobacco there is provided in a gas tight tobacco storage room an inert O.sub.2 lacking atmosphere with O.sub.2 between 0 and 5%, CO.sub.2 between 1 and 20% and the balance N.sub.2. This atmosphere is maintained until mortality of the pest. The system for providing this atmosphere includes essentially a generator, which can be a combustion chamber (1) associated with a catalytic chamber (2) (in the case of an open circuit system in which air is drawn from the atmosphere) or a catalytic chamber alone (in the case of a closed circuit system in which air is drawn from the tobacco storage room itself) and a cooling tower (3).The system is generally provided also with an evaporator (5) and a condenser (6) to control the humidity of the inert atmosphere, and a heat exchanger (7) in which the combustion heat is utilized to heat the inert atmosphere at a temperature which speeds up the mortality of the pest.Type: GrantFiled: December 16, 1983Date of Patent: May 19, 1987Assignee: Isolcell Europa S.r.l.Inventors: Dario Pruneri, Karl Zanon

Patent number: 4383538Abstract: Dry, compacted masses of tobacco are conditioned by inserting an array of parallel perforated probes into the mass and passing high pressure steam through the probes and probe perforations into the tobacco mass as the probes are inserted and withdrawn. The conditioning apparatus includes a frame supporting a probe array and a ram for moving the array toward and away from a tobacco mass supported by a conveyor. The probes are flexibly mounted to prevent bending, and extend through a stripper plate which is supported from the array by way of a latching mechanism. The stripper plate holds the tobacco mass in place to prevent lifting of the mass upon withdrawal of the probes.Type: GrantFiled: April 10, 1981Date of Patent: May 17, 1983Assignee: R. J. Reynolds Tobacco CompanyInventors: Hoyt S. Beard, Daniel G. Williard, Marvin G. Woempner

Patent number: 4366823Abstract: An improved process for expanding tobacco wherein tobacco components such as stems, midribs and veins are contacted with an alkaline-hydrogen peroxide solution to effect expansion, washed and then dried and/or roasted to produce an expanded tobacco material highly suitable for use in smoking products. Prior to contact with the alkaline hydrogen peroxide solution, the tobacco materials are subjected to a pretreatment step with a multivalent salt solution to prevent clumping and/or interadherence of the tobacco shreds which would otherwise occur during the drying step.Type: GrantFiled: June 25, 1981Date of Patent: January 4, 1983Assignee: Philip Morris, IncorporatedInventors: Norman B.
