Process Flow
Process Description
Raw Material Conditioning
Fresh Patchouli leaves are partially dried and conditioned under controlled temperature and humidity to improve enzymatic conversion and maximise essential oil quality.
Size Reduction
Conditioned leaves are chopped uniformly to improve steam penetration and enhance extraction efficiency.
Steam Distillation
Prepared Patchouli leaves are processed in specially designed stainless steel steam distillation vessels. Optimised steam flow ensures efficient extraction of aromatic compounds while preserving valuable patchoulol.
Advantages include:
- High oil recovery
- Uniform distillation
- Consistent product quality
Condensation
Essential oil vapours are condensed rapidly using high-efficiency shell-and-tube condensers to minimise aroma loss.
Florentine Oil Separation
Condensed oil and hydrosol are separated through precision-engineered Florentine separators.
Outputs include:
- Premium Patchouli Essential Oil
- Patchouli Hydrosol
Vacuum Polishing
The essential oil undergoes vacuum polishing to remove traces of moisture and improve clarity while maintaining its complex fragrance profile.
Quality Standardisation
Each production batch is analysed for:
- Patchoulol Content
- α-Bulnesene
- Specific Gravity
- Refractive Index
- Optical Rotation
- Moisture
- Colour
- Purity
