Douglas Fir
Douglas Fir
Mechotech designs and manufactures turnkey needles & twigs distillation plants for Douglas Fir (Pseudotsuga menziesii). We supply the complete machinery to process Douglas Fir (needles and twigs) into an essential oil configured to the client’s target specification. The catalogue describes Douglas fir oil as rich in α-pinene, β-pinene and bornyl acetate, for aromatherapy, cosmetics, perfumery and pharmaceutical use.
Mechotech’s Douglas Fir distillation plant is configured around the raw material and the target oil. It is built in SS 316L with integrated condensers and oil–water separation, PLC-based automation and full documentation, and is delivered as a commissioned turnkey system. The distillation mode is selected during process development.

Capacity is configured to raw-material supply, confirmed buyer volume and investment timeline; a pilot plant is recommended to validate parameters before scaling.
Manufacturing Process
Raw Material Preparation
Douglas Fir raw material is cleaned, sorted, and (where required) comminuted to the optimal particle size to maximise oil release during distillation.
Charging & Distillation
The prepared Douglas Fir charge is loaded into the SS 316L still and distilled by steam, hydro (hydrodistillation), vacuum, or pressure distillation — selected for the volatility and heat-sensitivity of the target oil.
Condensation
Vapours pass through an efficient multi-tube condenser with chilled-water circulation, condensing the volatile oil and hydrosol.
Oil–Water Separation
Condensate is separated in a stainless-steel Florentine flask; the essential oil is collected while the hydrosol is drawn off (and can be recovered as a co-product).
Polishing & Drying
The crude oil is polish-filtered and dried over anhydrous sodium sulphate (or by vacuum) to remove residual moisture.
Quality Control
Each batch of Douglas Fir oil is verified by GC-MS and physical parameters (specific gravity, refractive index, optical rotation) before release.

Key Features
SS 316L Construction
All product-contact surfaces are SS 316L for corrosion resistance and product purity, with CIP capability between batches.
Efficient Condensation
High-surface-area multi-tube condensers with chilled-water circulation condense the volatile oil and hydrosol.
Distillation Still / Extractor
The still (extractor) is configured for the distillation mode best suited to the feedstock, protecting heat-sensitive aroma compounds.
Hydrosol Recovery
Integrated separation allows the aromatic hydrosol to be recovered as a co-product.
Scalable Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.
