Carrying out steam distillation
Some other applications of steam distillation
The fundamental nature of steam distillation is that it enables a compoundor mixture of compounds to be distilled (and subsequently recovered) ata temperature substantially below that of the boiling point(s) of the individualconstituent(s).

The steam that is used for the distillation is generatedeither within the steel vessel that contains the plant material (by boilingwater contained at the base) or by an external boiler.

The vessel can be emptiedand recharged quickly and with the immediate reintroduction of steam thereis no unnecessary delay in the commencement of the distillation process.

The steam is produced at greater pressure than the atmosphere and therefore boils at above 100 degrees Celsius which facilitates the removal of the essential oil from the plant material at a faster rate and in so doing prevents damage to the oil.

Distillation appears to have been practiced throughout ancient times. Based upon the current interpretation Paolo Rovesti’s discovery of an earthenware distillation apparatus, the production or extraction of aromatic oils by means of steam distillation, has been known for 5000 years. During the fifth century AD, the famed writer, Zosimus of Panopolis, refers to the distilling of a divine water and panacea. Throughout the early Middle Ages and beyond, a crude form of distillation was known and was used primarily to prepare floral waters or distilled aromatic waters. These appear to have been used in perfumery, as digestive tonics, in cooking, and for trading.
