How does steam distillation work?

In many ways the Steam Distillation process is like the Hydrologic Cycle. This is sometimes referred to as Nature’s Distiller or “Rain in a Chamber”. There are in simple terms, three steps. They are: Evaporation, Condensation and Precipitation. Rain is actually distilled water but as it falls through our polluted atmosphere it immediately begins to pick up dust particles, bacteria, toxic fumes and other contaminants, which can then convert the pure rain into “Acid Rain”.

In a steam-distillation appliance, the shortcomings of the hydrologic cycle have been overcome. Water in the boiling tank comes to a boil which creates steam. The steam, being lighter than air, rises leaving virtually all of the biological and chemical impurities that may have been present in the boiling water behind. The pure steam then enters the cooling section where it is cooled and converted into pure steam-distilled water. Bacteria, protozoa and viruses are killed almost instantly during the boiling process. Salts, heavy metals, dead bacteria and other high boiling point substances do not rise with the steam, but rather are left behind in the boiling chamber to be dumped down the drain.

What Nature has shown us as a model, man has learned to improve on through the process of steam-distillation.
