Process Flow
Process Description
Raw Material Preparation
Fresh peppermint is cleaned and uniformly chopped to improve steam penetration and maximize essential oil recovery.
Steam Distillation
Prepared peppermint is charged into specially designed stainless steel distillation vessels. Controlled steam passes uniformly through the plant material, vaporizing volatile aromatic compounds without degrading sensitive components.
Advantages include:
- High oil recovery
- Superior aroma retention
- Uniform distillation
- Reduced thermal degradation
- Excellent batch consistency
Condensation
The essential oil vapors are rapidly condensed using high-efficiency shell-and-tube condensers to preserve volatile compounds.
Florentine Oil Separation
Oil and hydrosol are separated using precision Florentine separators.
Outputs include:
- Premium Peppermint Essential Oil
- Pharmaceutical-grade Hydrosol
Menthol Crystallization
Where required, peppermint oil undergoes controlled cooling and crystallization.
Benefits include:
- High-purity natural menthol
- Excellent crystal formation
- Pharmaceutical-grade product
- Higher product value
Vacuum Polishing
Final oil polishing removes traces of moisture and improves clarity while preserving aroma.
Quality Standardization
Each production batch is analyzed for:
- Menthol
- Menthone
- Menthyl Acetate
- Specific Gravity
- Optical Rotation
- Refractive Index
- Color
- Moisture
- Purity
- GC-MS Profile
