Executive Summary
A manufacturer of botanical ingredients required a fully automated, GMP-oriented Clove Essential Oil Distillation Plant to manufacture premium-quality Clove Essential Oil, Eugenol-Rich Oil, and specialty essential oil fractions for pharmaceutical, food, flavour, fragrance, cosmetic, and dental care industries.
The customer required a turnkey solution capable of maximising essential oil recovery, preserving natural eugenol content, minimising steam consumption, reducing processing time, and consistently producing export-grade oil compliant with international quality standards.
Mechotech successfully designed, engineered, manufactured, installed, and commissioned a Clove Essential Oil Distillation Plant incorporating advanced steam distillation, precision condensation, oil-water separation, condensate recovery, automated utility management, and intelligent PLC-SCADA automation.
Customer Background
The customer manufactures natural essential oils for pharmaceutical companies, dental care manufacturers, flavour & fragrance industries, food ingredient companies, cosmetic manufacturers, personal care brands, aromatherapy companies, and global essential oil exporters. With growing worldwide demand for natural Clove Oil and Eugenol, the customer required a modern, energy-efficient facility capable of continuous high-quality production.

Process Description
Raw Material Preparation
Premium-quality dried clove buds are cleaned and inspected before loading into stainless steel distillation vessels. Depending on customer requirements, cloves may be lightly crushed to improve oil release without affecting oil quality.
Steam Distillation
Steam generated in a high-efficiency boiler passes uniformly through the clove bed, extracting volatile essential oil compounds.
The process ensures:
- High eugenol preservation
- Uniform steam distribution
- Reduced processing time
- Consistent product quality
Condensation
Oil-laden vapours are condensed using high-efficiency shell-and-tube condensers designed for rapid heat transfer.
Benefits include:
- Efficient condensation
- Lower oil losses
- Reduced cooling water consumption
- Stable plant operation
Oil-Water Separation
Condensed liquid enters precision-engineered Florentine separators where Clove Essential Oil is separated from hydrosol.
Recovered products include:
- Premium Clove Essential Oil
- Clove Hydrosol (optional value-added product)
Oil Filtration
The separated oil passes through micron filtration systems to achieve excellent clarity while preserving natural aroma and active compounds.
Quality Standardisation
Each production batch is tested for:
- Eugenol Content
- Specific Gravity
- Refractive Index
- Optical Rotation
- Colour
- Moisture
- Purity
- Organoleptic Properties
Only batches meeting customer specifications proceed to packaging.
