Abstract
1356065 Puffing tobacco REYNOLDS LEASING CORP 23 Dec 1971 [28 April 1971] 60083/71 Heading A2C A process for treating tobacco comprises introducing tobacco into an impregnating zone, simultaneously introducing into said zone and into contact with said tobacco a stream of vapours of a compound having an atmospheric pressure boiling point between -50 and +80C., the temperatures of said tobacco and said vapour introduced into said zone' being, respectively, below and above the boiling point of said compound at the pressure prevailing therein, withdrawing the tobacco impregnated with said compound from said zone, controlling the rate of vapour introduction into said zone with respect to the rate of tobacco introduction thereinto such that the weight ratio of compound in the withdrawn impregnated tobacco is in the range of 5 to 200 parts by weight of compound per 100 parts by weight of tobacco (dry 'basis), and suddenly subjecting the withdrawn impregnated tobacco to vapour expanding conditions whereby the tobacco is also expanded. The apparatus used is similar to that described in Specification 1253183, but differs in the provision of a vapourizer 20 to vaporize the impregnating compound before it is introduced into the bottom end of the impregnator 4. A pressure responsive element 68 within the impregnator 4 controls the amount of liquid impregnating compound flow through a control valve 18 and hence the flow of vapours into the impregnator 4, Impregnated tobacco is withdrawn through a star feed valve 36 into a duct 38 leading to an expander 6 where it is expanded by treatment with a hot gas in the manner described in Specification 1222308. The reorderer 12 comprises an inclined rotating drum in which a fine spray of water restores the moisture content of the expanded tobacco to about 12 to 13%. The preferred impregnating compounds are hydrocarbons and halogenated hydrocarbons, especially trichloromonofluoromethane, but many suitable organic compounds are listed.
