Holy Basil
Mechotech designs and manufactures turnkey leaves oils distillation plants for Holy Basil (Ocimum tenuiflorum / Ocimum sanctum), also known as Tulsi, processing fresh leaves and tender stems into eugenol-rich essential oil and aromatic hydrosol. As a Holy Basil essential oil distillation plant manufacturer, we supply the complete steam-distillation line — leaf handling, distillation vessel, condenser, Florentine oil-water separation, and vacuum polishing — for the pharmaceutical, nutraceutical, food, fragrance, and Ayurvedic industries.
Mechotech's Holy Basil plant is engineered around the real chemistry of Tulsi leaf: gentle steam distillation releases the volatile phenylpropanoids and terpenoids — chiefly eugenol, along with methyl eugenol, caryophyllene and eucalyptol — without degrading heat-sensitive aroma compounds, while a matched Florentine separator recovers both the essential oil and a hydrosol co-product. Built in SS 316L with high-efficiency condensers, PLC-based automation and full batch documentation, each plant is delivered as a commissioned turnkey system to GMP, HACCP and AYUSH-aligned standards, with capacity and automation configured to the customer's requirement.

Manufacturing Process
Raw Material Reception & Cleaning
Freshly harvested Holy Basil (Tulsi) leaves and tender stems are inspected, cleaned of soil and foreign matter, and gently handled to minimise bruising before distillation.
Leaf Preparation & Charging
Cleaned leaves are loosely charged into the SS 316L steam distillation vessel, ensuring uniform steam permeation through the bed to maximise oil release.
Steam Distillation
Low-pressure steam passes through the leaf charge, volatilising eugenol, methyl eugenol, caryophyllene, eucalyptol and other characteristic Tulsi aroma compounds.
Condensation
Vapours pass through an efficient multi-tube condenser with chilled-water circulation, condensing the volatile essential oil and hydrosol.
Florentine Oil–Water Separation
Condensate is separated in a stainless-steel Florentine flask; the essential oil is collected while the aromatic hydrosol is drawn off and 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 and trace particulates.
Quality Control
Each batch of Holy Basil oil is verified by GC-MS for eugenol content and by physical parameters (specific gravity, refractive index, optical rotation) before release.
Storage & Packing
Essential oil and hydrosol are filled into light-protected, food/pharma-grade containers under batch-traceable, GMP-controlled conditions ready for dispatch.

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 maximise oil recovery and minimise losses of volatile top-notes.
Steam Distillation, Not Solvent Extraction
Holy Basil oil is recovered by steam / hydro-distillation of fresh leaf and tender stems rather than solvent extraction, preserving its eugenol-rich aroma; standardised tulsi extract powder is a separate product line.
Hydrosol Recovery
Integrated separation allows recovery of the aromatic hydrosol as a co-product.
Eugenol-Rich Oil Profile
Gentle steam distillation releases eugenol along with methyl eugenol, caryophyllene and eucalyptol, and each batch is GC-MS verified against an internal reference standard.
