Essential Oil Distillation Plants

In steam distillation, steam is passed through the raw material without direct contact with boiling water, which suits delicate or heat-sensitive feedstock. In hydro distillation (hydrodistillation), the material is submerged and boiled directly in water, which can suit denser or more heat-tolerant material. Mechotech engineers each plant around the feedstock and target oil to determine the right method.

Raw aromatic material is loaded into the still, heated with steam or water to vaporise the volatile oil, and the vapour is condensed and separated in a stainless-steel Florentine flask into essential oil and hydrosol. Mechotech's turnkey plants integrate this process with efficient condensation and oil-water separation, engineered and commissioned as a complete system.

There is no single best method — it depends on the feedstock's heat sensitivity, oil volatility, and desired hydrosol yield. Mechotech designs the distillation method (steam, hydro, vacuum, or pressure) around the specific aromatic material and the client's target output. For oil-rich feedstock such as citrus peel, a cold-press (expression) extractor is used instead of distillation, since no heat is involved.

Mechotech's essential oil distillation plants are engineered for commercial and industrial-scale production — turnkey systems built GMP-compliant in SS 316L, with PLC-based automation, CIP (clean-in-place) capability, and full documentation — rather than the small-batch equipment used for home or hobbyist distillation.

Batch distillation suits multi-product operations processing different feedstocks or oils in sequence, while continuous distillation suits high-volume, single-feedstock production. Mechotech engineers each plant around your feedstock mix, target throughput, and investment scale — see our batch vs continuous plant comparison for the general trade-offs, which apply to distillation as well as solvent extraction.

Essential oil is only the volatile aromatic fraction of a plant, recovered by distillation (or cold pressing for oil-rich feedstock) — it does not include the non-volatile flavour, colour, and pungency compounds. A spice oleoresin is a broader solvent extract that captures both the volatile oil and the non-volatile compounds, giving a more complete flavour and colour profile used mainly in food and flavour applications. If you need the complete oleoresin rather than the volatile oil alone, see our spices oleoresin extraction plant range.

Cost depends on the distillation method (steam, hydro, vacuum, or pressure, or a cold-press extractor for oil-rich feedstock), batch or continuous configuration, and target throughput, so we don't quote a fixed price without those details. Share your feedstock and target output through a project consultation and we'll provide a project-specific quotation.
