摘要： A tobacco expansion method is provided whereby cured tobacco is first moistened with a humectant solution, as is conventional in the industry, to increase the resident liquids thereof. Next, the prepared tobacco in shredded form is placed in a sealed chamber and the chamber evacuated to vaporize a portion of the resident liquids. Next, ethyl alcohol vapor is allowed to enter the pressure chamber below 70 mm (Hg) absolute to prevent a water-ethyl alcohol azeotrope from forming. Thereafter, a hydrocarbon vapor, such as n-pentane vapor, is directed into the chamber and the pressure restored to atmospheric. The n-pentane vapor diffuses into the cellular structure of the tobacco with the assistance of the ethyl alcohol, whereafter the tobacco is heated and the n-pentane and ethyl alcohol acts as a propellant to expand the tobacco.

摘要翻译：提供了一种烟草膨胀方法，其中如工业上常规的那样，首先将经过烘烤的烟草用保湿剂溶液润湿以增加其驻留液体。接下来，将制成的碎烟丝状物放置在密封室中，抽空该室以蒸发一部分驻留液体。接下来，允许乙醇蒸气进入压力室低于70mm（Hg）绝对值以防止形成水 - 乙醇共沸物。此后，将碳氢化合物蒸气如正戊烷蒸气引入室中，压力恢复到大气压。正戊烷蒸气在乙醇的帮助下扩散到烟草的细胞结构中，然后加热烟草并且正戊烷和乙醇充当推进剂以扩展烟草。
