Hemlock
Hemlock
Mechotech designs and manufactures turnkey needles and twigs distillation plants for hemlock (Tsuga spp.). The catalogue describes the oil from hemlock twigs and needles as rich in α-pinene, borneol and limonene, for aromatherapy, skincare, perfumery and related use.
Mechotech’s hemlock 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 and operating parameters are established during process development and pilot validation. Hemlock twigs and needles are bulky conifer foliage, so the line is built around cutting to short lengths and a still sized for a bulky, springy charge.

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
Hemlock twigs and needles are cleaned and cut to short lengths so that steam penetrates the bulky foliage evenly; the cut size and charge density are set during process development.
Charging & Distillation
The prepared Hemlock charge is loaded into the SS 316L still and distilled by steam, hydro, vacuum or pressure distillation, selected during process development for the volatility and heat-sensitivity of the target oil.
Condensation
Vapours pass through a multi-tube condenser with chilled-water circulation, condensing the oil and hydrosol.
Oil–Water Separation
Condensate is separated in a stainless-steel Florentine flask; the oil is collected and 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 is sampled for GC-MS profile and physical parameters — specific gravity, refractive index, optical rotation — against the client’s specification.

Key Features
SS 316L Construction
Product-contact surfaces are SS 316L for corrosion resistance and product purity, with CIP capability between batches.
Efficient Condensation
Multi-tube condensers with chilled-water circulation condense the volatile oil and hydrosol and limit loss of volatile top-notes.
Foliage-Charge Distillation
The still is configured for bulky twig-and-needle charges, with the distillation mode set during process development.
Hydrosol Recovery
Integrated oil–water separation allows the aromatic hydrosol to be drawn off and recovered as a co-product.
Scalable Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.
