Abstract

드라이 아이스로 팽화시킨 담배(D,I,E,T)에서, 가공 담배를 함침기용기(1)내로 장입시키고, 이 함침기 용기를 이어서 밀폐시키고, 이 함침기 용기 내의 대기를 퍼징시키고, 충전용기(3)에서 얻은 저압 기체 이산화탄소로 예정된 압력으로 가압시킨다. 함침기 용기(1)를 기체 이산화탄소와 액체 이산화탄소의 평형 혼합물이 들어있는 공정 용기(2)에 연결시키고, 공정용기(2)와 충전 용기(3)사이에 존재하는 압력 차등으로 액체 이산화탄소를 공정 용기(2)로부터 함침기 용기(1)로 이송되게 하여서 담배를 모두 액체 이산화탄소 중에 함침시킨다. 액체 이산화탄소가 담배의 셀 내로 침투하도록 충분히 긴 시간 동안 액체 이산화탄소를 함침기 용기(1)내로 유지시키고, 과잉의 액체 이산화탄소를 제거한다. 함침기 용기(1)내의 압력을 감압시켜서 담배 셀 내의 액체 이산화탄소를 응고시키고, 이어서, 함침기 용기(1)를 열어서 냉동시킨 담배를 이탈시킨다. 최종적으로, 담배를 승화기 내에서 가열시켜서 담배 셀 내의 고체 이산화탄소를 급속하게 기화시킴으로써 담배를 팽화시킨다.In cigarettes (D, I, E, T) swelled with dry ice, the processed tobacco is charged into the impregnator container 1, the impregnator container is subsequently sealed, the atmosphere in this impregnator container is purged, and filled The low pressure gaseous carbon dioxide obtained in the vessel 3 is pressurized to a predetermined pressure. The impregnator vessel (1) is connected to a process vessel (2) containing an equilibrium mixture of gaseous carbon dioxide and liquid carbon dioxide, and liquid carbon dioxide is transferred to the process vessel by the pressure differential present between the process vessel (2) and the filling vessel (3). All the cigarettes are impregnated in liquid carbon dioxide by being transferred from (2) to the impregnator container 1. The liquid carbon dioxide is kept in the impregnator container 1 for a sufficiently long time so that the liquid carbon dioxide penetrates into the cells of the cigarette, and the excess liquid carbon dioxide is removed. The pressure in the impregnator container 1 is reduced to coagulate the liquid carbon dioxide in the tobacco cell, and then the impregnator container 1 is opened to release the frozen tobacco. Finally, the cigarette is heated in a sublimer to swell the cigarette by rapidly vaporizing solid carbon dioxide in the tobacco cell.

The method of claim 1, wherein the impregnator container is purged with low pressure gaseous carbon dioxide obtained from a filling container.

The method of claim 2, wherein the impregnator container is pressurized by gaseous carbon dioxide at a predetermined pressure from the filling container.

The method of claim 2 or 3, wherein the movement of liquid carbon dioxide from the process vessel to the impregnator vessel is achieved by simultaneously connecting the filling vessel and the process vessel to the impregnator vessel.

The method of swelling cigarettes according to claim 4, wherein the carbon dioxide gas that has been boiled and replaced when the liquid carbon dioxide is introduced into the impregnator container is collected in a filling container.

6. The method of inflating tobacco according to claim 5, wherein the pressure in the impregnator container is reduced by setting a flow relationship between the impregnator container and the carbon dioxide recovery device including the carbon dioxide gas recovery mechanism.

7. The method of swelling tobacco according to claim 6, wherein the carbon dioxide gas collected in the recovery mechanism is recovered to a process vessel through a gas recovery device for liquefying at least part of the gas again.
