Essential oil extraction technique from very primitive to the advance level in the ppt all types of extraction technique is described into the common ppt some the them are hydro distillation, hydro- steam distillation, steam distillation and many more in that
2. Essential Oils
• Volatile oil containing odoriferous
elements of the aromatic plant.
• Highly viscus and posses healing
properties
3. Extraction of
Essential Oils
Essential oil can be extracted
by the different extraction
techniques.
These extraction can be
performed on lab or
production level.
4. 01.
Distillation
Distillation is the one of oldest
and one of the fundamental
technique to extract essential
oils from plants.
It is also called the old school
method of extraction.
There are 3 types of
distillation.
5. Steam distillation
This is dry steam
distillation technique
which is use to distill
hard material like
sandalwood.
03.
Hydro / Water
distillation
This technique is
performed when we
need distill soft
material like flowers.
01. 02.
Hydro steam
distillation
This distillation
technique is used to
distill the grassy
material like
lemongrass.
6. Hydro distillation
• This distillation technique is used to
distill delicate the material like
flowers. This can be used as
traditional or in the modernize way.
• The traditional way to use this
method is Deg Bhapka. Or in
modernize way we can set up the
hydro distillation unit (Clevenger
Apparatus).
7. Process of Deg & Bhapka
Calibrate & Make
unit odor less
Selection & loading
of material with
water into the Deg
Seal the deg with
the mixture of
Multani mitti &
cotton
Collect the bhapka
when process is
done
Examine the whole
unit for any possible
leakages & light the
furnace
Connect the deg &
bhapka using
chonga (Bamboo
pipe)
8. Hydro
Steam distillation
Grassy material is extracted
from this technique. In this
method we took water under
the perforated plate following
the material.
Then heat up the material and
start the distillation.

9. Process of Hydro
Steam distillation
Calibrate & Make
unit odor less
Fil the water in the
tank situated under
the perforated
plate
Selection & weight
the material and
then load
Vapors change into
the liquid and then
collect it in the
receiver
vapor of water &
material reaches to
the condenser
Then we lit the
furnace.
10. Steam Distillation
Steam distillation is the one of the
modernize technique of distillation.
This method of distillation used for
woody or hard material.
This the costliest distillation method
in all the above.
11. Process of Steam distillation
Calibrate & Make
unit odor less
Selection & loading
of material with
water into the
Extractor
Heat the boiler to
start the flow of
steam
Cover the material
by the second
perforated plate.
After closing the
lid, we start the
flow of steam.
after the process
we collet the oil in
the receiver.
12. 02.
Solvent Extraction
This method is used to extract
oil from different seeds and also
for different flowers.
In this extraction we use
ethanol or n-Hexane as solvent.
Solvent extraction is also known
as Liquid liquid extraction.
14. Process of Solvent Extraction
Calibrate & Make
unit odor less
Selection & loading
of material with
water into the
Extractor
Dip the material
into the solvent
When the process is
done we recover
the solvent.
After some time
sippning process
takes place.
Start the flow of
heat by the heating
