    • An expanding apparatus continuously expands a material, e.g., a tobacco material and supplies gaseous carbon dioxide as an expanding agent to an impregnating vessel by an expanding agent supply to maintain a predetermined impregnating pressure. The material is continuously supplied to the impregnating vessel by a material supply while increasing the pressure of the material. The material is continuously discharged from the impregnating vessel by a material discharge while decreasing the pressure of the material. The expanding agent supply has a heat exchanger to perform heat exchange between carbon dioxide to be supplied to the impregnating vessel and a coolant, thereby cooling carbon dioxide. The state of carbon dioxide to be supplied to the impregnating vessel is controlled in accordance with the temperature or the like of the tobacco material discharged from the impregnating vessel, so that carbon dioxide is effectively impregnated and no dry ice is formed in the material discharge or the like.
    • 膨胀装置连续地膨胀材料,例如烟草材料,并通过膨胀剂供应物将膨胀剂的气态二氧化碳提供给浸渍容器以保持预定的浸渍压力。 该材料通过材料供应被连续地供应到浸渍容器,同时增加材料的压力。 该材料通过材料排出从浸渍容器中连续排出,同时降低材料的压力。 膨胀剂供给装置具有热交换器,以进行向浸渍容器供给的二氧化碳和冷却剂之间的热交换,由此冷却二氧化碳。 根据从浸渍容器排出的烟草材料的温度等来控制供给到浸渍容器的二氧化碳的状态,使得有效地浸渍二氧化碳,并且在材料排出物中不形成干冰 类似。
