This distillation is very similar to the hydro-distillation, the difference is that in this method the still contains a grid which keeps the plant material above the water level. This arrangement can be compared to a kitchen steamer basket, the plant material is supported in a "basket" over boiling water, thus exposing the plant material only to the rising steam vapors. The water is boiled below the charge and wet steam passes through the plant material It is important in both water/steam and steam distillation that the still is packed evenly and not too tightly so that steam can extract from the complete charge efficiently. Over packing of the still can cause the steam to force "rat holes" through the charge and leave other parts of the charge unextracted. |

This distillation is very similar to the hydro-distillation, the difference is that in this method the still contains a grid which keeps the plant material above the water level. 蒸馏与水蒸馏十分相似，差别仅在于，在这种方法中蒸馏室包含有一个栅格，使得植物材料处于水面以上。This arrangement can be compared to a kitchen steamer basket, the plant material is supported in a "basket" over boiling water, thus exposing the plant material only to the rising steam vapors. 这种布置科比之于厨房里的蒸笼，植物材料别置于沸水上面的“笼屉”之上，因而将植物材料仅仅暴露于升腾的水蒸气。The water is boiled below the charge and wet steam passes through the plant material水在负载下面沸腾，湿蒸汽穿过植物材料。 It is important in both water/steam and steam distillation that the still is packed evenly and not too tightly so that steam can extract from the complete charge efficiently. 在水/蒸汽和蒸汽蒸馏中均匀而不过紧地包裹蒸馏室都是重要的，只有如此，蒸汽才能有效地从起步负载上提取材料。Over packing of the still can cause the steam to force "rat holes" through the charge and leave other parts of the charge unextracted.对蒸馏室过度的包裹可能导致蒸汽压力形成穿透负载的“鼠洞”，而使得其余部分负载上的材料得不到提取。 |
