Executive Summary
A manufacturer of essential oils required a fully automated, GMP-oriented Cardamom Essential Oil Distillation Plant to produce premium-quality Cardamom Essential Oil from carefully selected Green Cardamom (Elettaria cardamomum). The objective was to maximise oil recovery, preserve delicate aromatic compounds, reduce steam consumption, and consistently produce export-grade essential oil for international flavour, fragrance, pharmaceutical, nutraceutical, cosmetic, and aromatherapy markets.
Mechotech successfully designed, engineered, manufactured, supplied, installed, and commissioned a Cardamom Essential Oil Distillation Plant integrating advanced steam distillation, precision condensation, oil-water separation, aroma recovery, condensate recycling, energy-efficient utilities, and intelligent PLC-SCADA automation.
Customer Background
The customer manufactures and exports essential oils to flavour & fragrance companies, food ingredient manufacturers, pharmaceutical companies, nutraceutical manufacturers, cosmetic industries, aromatherapy product companies, personal care manufacturers, and international essential oil distributors. To meet increasing worldwide demand for natural essential oils, the customer required a modern turnkey distillation facility with high productivity and international quality compliance.
Customer Challenges
Before modernisation, the customer encountered:
- Low essential oil recovery
- Loss of delicate aroma compounds
- High steam consumption
- Long distillation cycles
- Manual operation
- Inconsistent oil quality
- High utility costs
- Limited batch capacity
- Difficulty maintaining export specifications
Project Objectives
Mechotech was commissioned to develop a facility capable of:
- Processing 10 MT/day of Green Cardamom
- Maximising essential oil recovery
- Preserving natural aroma compounds
- Reducing steam and utility consumption
- Improving batch consistency
- Documentation to support the customer's quality and regulatory qualification
- Supporting expansion

Process Description
Raw Material Preparation
Premium-quality cardamom capsules are cleaned, inspected, and optionally crushed to optimise essential oil release while preserving delicate aromatic compounds.
Steam Distillation
Prepared cardamom is loaded into stainless steel distillation vessels where clean saturated steam passes uniformly through the raw material.
The process ensures:
- Preservation of volatile aroma compounds
- Uniform steam distribution
- Minimal thermal degradation
- High batch consistency
Condensation
The vapour mixture of steam and essential oil passes through high-efficiency shell-and-tube condensers where it is rapidly cooled.
Benefits include:
- Efficient condensation
- Reduced oil losses
- Energy-efficient design
- Stable operation
Oil-Water Separation
Condensate enters precision-designed Florentine separators (oil separators), where the essential oil is naturally separated from aromatic water (hydrosol).
Recovered products include:
- Premium Cardamom Essential Oil
- Cardamom Hydrosol (optional commercial product)
Oil Filtration
The essential oil undergoes fine filtration to remove suspended particles while maintaining natural aroma and clarity.
Quality Standardisation
The oil is tested and standardised for:
- Specific Gravity
- Refractive Index
- Optical Rotation
- Cineole Content
- Moisture
- Purity
- Colour
- Organoleptic Characteristics
