Hydro Distillation Method

Hydro Distillation Method

Hydro distillation is a variant of steam distillation. It is a common extraction process to separate phytochemical compounds from plant material. For the hydro distillation extraction, plant material is soaked for some time in water after which the mixture is heated and volatile materials are carried away in the steam, condensed and separated.

Hydro distillation can be referred by one of the two methods: Clevenger distillation - the material to be extracted is immersed in water, which is then boiled. Steam distillation - steam passes through a bed of the material to be extracted. Hydro distillation with Clevenger trap is used for the extraction of volatile oil (essential oil) and steam distillation is used in Industries for the isolation of volatile oil.

Hydro distillation is sometimes used instead of steam distillation. This process of extraction is one of the most used traditional methods of extraction. In this process, steam pass via powdered wood in hydro distillater, the powder is soaked in to water. A variant of steam distillation in which material is soaked for some time in water after which the mixture is heated and volatile materials are carried away in the steam, condensed and separated.
