Patent number: 4388932Abstract: Tobacco which has been increased in filling power by a conventional tobacco expansion process can be further increased in filling power by a post expansion heat treatment. The post expansion heat treatment comprises contacting the expanded tobacco produced by a conventional expansion process with a gaseous medium, such as air and/or steam, at a temperature of from about 200.degree. F. to about 450.degree. F. The post expansion heat treatment is preferably conducted at a lower temperature than the temperature of the heating step of the expansion process, and thus can be more easily controlled, while providing an additional increase in filling power. The product of the post expansion heat treatment process of this invention has been found to be as acceptable in subjective smoking characteristics as the expanded tobacco which is treated by the process.Type: GrantFiled: December 31, 1980Date of Patent: June 21, 1983Assignee: Philip Morris, IncorporatedInventors: Henry B.

-
Patent number: 4340073Abstract: A process for expanding tobacco is provided which employs liquid carbon dioxide as the expansion agent. Tobacco is contacted with liquid carbon dioxide to thoroughly impregnate the tobacco with the liquid carbon dioxide. The carbon dioxide impregnated tobacco is maintained at a temperature no lower than -2.degree. C. and under conditions of temperature and elevated pressure such that all or substantially all of the carbon dioxide which is in contact with the tobacco is in liquid form. After the impregnation has been completed, any excess liquid carbon dioxide which may be present with the tobacco may be removed from the tobacco. The elevated pressure is then reduced in order to convert the liquid carbon dioxide to solid carbon dioxide within the tobacco structure.Type: GrantFiled: February 12, 1974Date of Patent: July 20, 1982Assignee: Philip Morris, IncorporatedInventors: Roger Z. de la Burde, Patrick E.

Patent number: 4336814Abstract: This invention relates broadly to an improved process for expanding tobacco and involves certain modifications of the basic process for expanding tobacco comprising the steps of (1) contacting the tobacco with liquid carbon dioxide to impregnate the tobacco with the liquid carbon dioxide, (2) subjecting the liquid carbon dioxide-impregnated tobacco to conditions such that the liquid carbon dioxide is converted to solid carbon dioxide and (3) thereafter subjecting the solid carbon dioxide-containing tobacco to conditions whereby the solid carbon dioxide is vaporized to cause expansion of the tobacco. The present invention pertains, in one embodiment, to an improvement in the basic process which involves controlling the moisture content of the tobacco which is employed in the first step of the basic process.Type: GrantFiled: September 5, 1979Date of Patent: June 29, 1982Assignee: Philip Morris IncorporatedInventors: Larry M.
