The presented diagram gives information about how essential oil is produced to become a material for perfume production.
Overall, the procedure consists of four primary stages in a relatively complex apparatus, which is mainly to infuse the oil with aroma, commencing with the heating process and culminating in two distinct outcomes, namely essential oil and aromatic water.
The process begins with the first tank, which contains water. The water is then heated by fire to be converted into steam, which is subsequently directed to another tank via a small tube. In the second container, steam flows through a thick layer filled with aromatic plants with the purpose of creating a mixture that includes steam and oil vapor. In this stage, steam is utilized to extract the oil from the aromatic plants by taking advantage of high temperatures and to carry the oil vapor to further processing steps.
In the third tank, an inlet of cold water, situated at the bottom of the tank, and an outlet of hot water, positioned on the top, are used to condense the previous mixture. This phase, known as the condenser phase, is applied to transform the steam and oil vapor into liquid, which is then channeled into the final tank. Eventually, thanks to its lower density, essential oil floats to the top of the tank and can be extracted using a tap. Concurrently, the aromatic water, called the hydrolat, is sent elsewhere for additional manufacturing purposes.
