The visual illustrates the linear process by which plant materials are utilized to produced refined essential oil.
Overall, this process involves four main separated physical and chemical stages, commencing with water being boiled and culminating with the collection of essential oil and by product, hydrolat. Also, these stages take place in perfume manufacturing plant, equipped with advanced machinery and expertized staff.
At the beginning of the process, fire is used to boil water in a container in order to produce steam. The steam is then subjected along to the vessel to the second stage where it passes through another container densed with aromatic plants, resulting in the mixture of steam and oil vapor.
The ensuing phase involves the condensation where the resultant combination passes through the coil in a condenser containing hot and cold water in order to form water and essential oil. To wrap up the process, the products from the previous stage is taken to a separating device where they are separated into refined essential oil and aromatic water.
