After condensing the steam, you can separate the essential oil from the hydrosol (the byproduct) using gravity separation and skimming techniques.
Lavender essential oil has numerous benefits and uses, including aromatherapy for relaxation, skincare for its antibacterial and anti-inflammatory qualities, and improving sleep.

The Process of Steam Distillation for Extracting Lavender Essential Oil

To extract lavender essential oil using steam distillation, start by harvesting the lavender plants and setting up the distillation equipment. Then, add water to the still and heat the mixture, allowing steam to carry the essential oil vapors from the plant material.

Finally, condense and collect the steam to separate it from the essential oil, resulting in a pure extraction of lavender essential oil.

Harvesting lavender plants

Harvesting lavender plants is a critical first step in the steam distillation process. As a lavender farmer, it’s essential to choose mature plants that have just started to bloom for optimal oil production. You can count the open blooms on a few flower heads to ensure that at least 30% of the flowers are open. You will want to distill before about 90% of the flowers have bloomed in order to maximize your oil yield.

The best time to harvest is early in the morning after dew has evaporated, as this can maximize the aromatic compounds in the plant material. As the day gets hotter, lavender releases its essential oil as a way to regulate the temperature of the plant, much like sweating in humans. Ensuring each sprig is carefully cut at its base helps maintain plant health for future growth cycles and effective oil extraction.

Following these guidelines ensures high-quality essential oils with a robust aroma and adds longevity to your lavender farming practice.

Setting up the distillation equipment

To set up the distillation equipment for steam distilling lavender essential oil, you will need a few key components. Firstly, choose a still or distillation apparatus that can accommodate the amount of lavender plant material you have harvested.

Make sure it is made of stainless steel or copper to ensure durability and efficient heat conductivity.

Next, assemble the various parts of the still, including the boiling tank, cook tank, plant material basket, condenser, collection container, and thermometer. Connect them securely using appropriate fittings and seals to prevent any leaks during the distillation process.

Once your setup is complete, place the lavender plant material into the cook tank along with an adequate amount of water in the boiling tank. In some distillation set ups the cook tank and the boiling tank are the same. In this case, use your strainer basket to keep the plant material out of the water. Plant material should never touch the water during steam distillation.

Remember to position the condenser in such a way that it allows adequate cooling of steam vapors as they travel through its coils. This will enable effective condensation and separation of essential oil from water vapor.

Heat your setup gradually by applying heat under the boiling tank. Monitor the temperature carefully using a thermometer to ensure optimal conditions for releasing essential oils without burning them.

Adding water and heating the mixture

To start the steam distillation process for extracting lavender essential oil, you will need to add water and heat the mixture. This step is crucial in releasing the aromatic properties of the lavender plant material. Here is a simple guide to follow:

Fill the distillation apparatus, such as a still, with water. The amount of water needed will depend on the size of your apparatus and the quantity of lavender plant material.
Place the lavender plant material into a basket or container inside the still. Make sure to evenly distribute it for better extraction.
Securely seal the still to prevent any steam from escaping during the distillation process.
Set up a heat source, such as a burner or electric stove, underneath the still and turn it on.
Gradually increase the temperature to bring the water to a boil. It is important not to rush this process as it allows for efficient extraction of essential oils.
As the water boils, steam will be produced and rise through the plant material, carrying with it the essential oil vapors.
The steam will then pass through a condenser, where it cools down and condenses back into liquid form along with essential oils.
Collect this mixture of water and essential oils in a separate container.

Condensing the steam and collecting the essential oil

After the lavender plant material has been heated and the steam is generated, it’s time to condense the steam and collect the essential oil. This step is crucial in obtaining pure and high-quality lavender essential oil. Here’s how it’s done:

The steam containing the essential oil vapors is passed through a condenser, which cools down the steam and converts it back into a liquid form.
The cooled liquid, now a mixture of floral water (called hydrosol) and essential oil, flows out of the condenser and into a separate container known as a separator.
In the separator, gravity comes into play as the heavier floral water (hydrosol) sinks to the bottom, while the lighter essential oil floats on top.
A spigot or valve at the bottom of the separator allows you to drain out or separate the water from the essential oil. If your still is very large, it is worthwhile to purchase an essencier. This piece of equipment will automatically separate the essential oil and hydrosol for you.
Carefully collect and transfer the separated lavender essential oil into dark glass bottles with pressure caps for storage or further processing.
Store essential oil in a cool, dark area for up to six years. As you use the essential oil, rebottle into smaller dark glass bottles to minimize headspace.

Understanding Hydrosol in Lavender Distillation

Hydrosol is the byproduct (or as a like to call it, the coproduct) of steam distillation, containing water-soluble components and a subtle aroma. Discover more about the purpose of hydrosol and how to separate it from lavender essential oil.

Read on to enhance your understanding of this valuable aspect of lavender distillation.

Definition and purpose of hydrosol

Hydrosol is a byproduct of the steam distillation process used to extract lavender essential oil. It is the liquid that remains after the steam and essential oil have been condensed and separated.

Hydrosol has its own unique properties and benefits, making it a valuable product in its own right.

The purpose of hydrosol is not only as a byproduct but also as a separate product itself. It can be used as a natural skin toner, facial mist, or even added to bathwater for a soothing and relaxing experience.

The hydrosol contains trace amounts of the essential oil (about .01%), along with water-soluble compounds from the plant material, giving it gentle therapeutic properties.

Separating hydrosol from essential oil

Hydrosol is a byproduct of the steam distillation process, and it refers to the water that remains after the essential oil has been extracted. Separating hydrosol from essential oil is an important step in lavender distillation, as both have distinct properties and uses. Here’s how to separate hydrosol from lavender essential oil:

Collection: Once the steam and essential oil vapor are condensed, they form a mixture of water and oil. This mixture is collected in a separating vessel called a separator, decanter, or essencier.
Gravity Separation: Because hydrosol is heavier than essential oil, gravity separation can be used to separate the two. The collected mixture is left to sit undisturbed for some time until the hydrosol settles at the bottom and the essential oil floats on top. An essencier or a separatory funnel can be used at this point to drain the hydrosol from the bottom of the mixture.
Skimming: To separate the top layer of essential oil from the bottom layer of hydrosol, you can use a skimming tool like a pipette or spoon. Carefully remove the essential oil from the surface without disturbing or mixing it with the hydrosol.
Filtering: If there are any small droplets of hydrosol remaining in the extracted essential oil, you can use filtration methods like cheesecloth or filter paper to strain out any impurities. This ensures that your lavender essential oil is pure and free from any unwanted particles.
Storage: After separating hydrosol from lavender essential oil, store each component separately in appropriate containers. Hydrosols are typically stored in dark-colored glass bottles with spray tops, while essential oils are stored in amber glass bottles with tight caps. Hydrosol should be periodically checked for its pH level and for signs of a “bloom”.
