Essential oil distillation plant

Types of Essential Oil Distillation Plant

• Steam Distillation Equipment

  The steam distillation apparatus is the most commonly used equipment for extracting essential oils from plant materials. This method involves passing steam through plant material, which causes the released plant cellular water and essential oils vapour. The vapours then condense back into liquid form in a separate vessel. The steam distillation setup usually includes a boiler, a condenser, and a collection flask. Steam distillation equipment is ideal for extracting oils from tough plant materials like roots, seeds, and wood.

• Water Distillation Equipment

  This distillation type uses water to extract essential oils, which is similar to steam distillation but involves boiling the plant material submerged in water. As the water boils, it releases both the essential oil and steam, which is then condensed and collected as the water level drops. Water distillation equipment is typically less expensive and easier to set up than steam distillation but often yields smaller amounts of oil. It is well-suited for delicate plant materials like leaves and flowers.

• Solvent Extraction Equipment

  Solvent extraction is used when steam or water distillation is not effective in producing the oil, especially for plant materials with low oil content. This method uses a food-grade solvent like ethanol or hexane to dissolve the essential oil from the plant material. After the oil is extracted, the solvent is evaporated, leaving behind pure essential oil. Solvent extraction equipment typically includes an extractor, evaporator, and condenser. While the equipment is suitable for large-scale production of highly aromatic oils like jasmine and rose.

• CO2 Extraction Equipment

  CO2 extraction is a more modern method that uses carbon dioxide in a supercritical state to extract essential oils. Supercritical CO2 acts like both a gas and a liquid, dissolving and extracting oils efficiently without leaving behind residue as a solvent typically would. This equipment consists of a CO2 extractor and a separator. It produces highly concentrated, pure oils while being durable for long-term use. It also extracts oils from a wide variety of plant materials and can be adjusted to extract different compounds.

• Fractional Distillation Equipment

  Fractional distillation equipment separates components of essential oils based on their boiling points. This allows for the collection of specific desired fractions of oil. This method refines and purifies oils by isolating key compounds. The equipment typically includes a fractional column, condenser, and collection flasks. It is used for refining oils to enhance their purity and potency. Fractional distillation equipment works well for oils with multiple useful components requiring separation, such as rosemary and eucalyptus oils.
