Executive Summary
A multinational manufacturer of essential oils and botanical ingredients required a fully automated, GMP-oriented Eucalyptus Essential Oil Distillation Plant to manufacture premium-quality Eucalyptus Essential Oil standardised for 1,8-Cineole (Eucalyptol) content. The oil was intended for pharmaceutical formulations, inhalation products, cough and cold remedies, cosmetics, aromatherapy, personal care, and industrial applications.
The customer sought a turnkey solution capable of maximising oil recovery, preserving volatile constituents, minimising steam and utility consumption, and consistently producing export-grade essential oil conforming to international quality standards.
Mechotech successfully designed, engineered, manufactured, supplied, installed, and commissioned an Eucalyptus Essential Oil Distillation Plant incorporating advanced steam distillation, precision condensation, high-efficiency oil-water separation, condensate recovery, energy optimisation, and PLC-SCADA automation.
Customer Background
The customer supplies Eucalyptus Essential Oil to pharmaceutical manufacturers, personal care companies, cosmetic manufacturers, aromatherapy brands, household product manufacturers, veterinary product companies, flavour & fragrance industries, and international essential oil exporters. Growing global demand for pharmaceutical-grade eucalyptus oil required investment in a modern, high-capacity production facility.

Process Description
Raw Material Preparation
Fresh eucalyptus leaves are received, inspected, cleaned, and, where required, mechanically chopped to improve steam penetration and maximise oil recovery.
Steam Distillation
Prepared leaves are charged into stainless steel distillation vessels where saturated steam passes uniformly through the biomass.
The optimised process provides:
- High essential oil recovery
- Uniform steam distribution
- Reduced processing time
Condensation
The vapour mixture is cooled in high-efficiency shell-and-tube condensers designed for heat transfer.
Benefits include:
- Efficient condensation
- Minimal oil loss
- Reduced cooling water consumption
- Stable continuous operation
Oil-Water Separation
Condensed liquid enters precision Florentine separators where essential oil is separated from hydrosol through density difference.
Recovered products include:
- Premium Eucalyptus Essential Oil
- Eucalyptus Hydrosol
Oil Filtration
The essential oil is passed through micron filtration systems to remove impurities while maintaining its natural aroma, clarity, and chemical profile.
Quality Standardisation
Each production batch is analysed for:
- 1,8-Cineole Content
- Specific Gravity
- Refractive Index
- Optical Rotation
- Moisture
- Purity
- Colour
- Organoleptic Characteristics
Only oil meeting customer specifications is released for packaging.
