Executive Summary
A luxury fragrance and cosmetic ingredient manufacturer required a fully automated, GMP-oriented Rose Essential Oil & Rose Water Distillation Plant capable of producing Rose Otto (Rose Essential Oil), Premium Rose Water (Hydrosol), and high-quality aromatic intermediates for premium perfumery, cosmetics, pharmaceuticals, food, and wellness industries.
The customer required a turnkey facility capable of processing large volumes of freshly harvested rose petals immediately after harvest to preserve volatile aromatic compounds, maximise oil recovery, reduce steam consumption, and consistently manufacture export-quality products to the customer's quality and regulatory requirements, with documentation to support qualification.
Mechotech successfully designed, engineered, manufactured, supplied, installed, and commissioned a Rose Distillation Plant incorporating advanced petal handling, hydro-distillation, cohobation (hydrosol recycling), steam distillation, precision Florentine oil separation, vacuum oil polishing, intelligent PLC-SCADA automation, and energy recovery systems.
Customer Background
The customer supplies premium botanical ingredients to Luxury Perfume Manufacturers, Cosmetic Companies, Pharmaceutical Manufacturers, Premium Skincare Brands, Aromatherapy Companies, Spa & Wellness Chains, Gourmet Food Manufacturers, and International Essential Oil Exporters. Growing global demand for authentic natural rose ingredients encouraged the customer to establish a modern, automated, GMP-oriented manufacturing facility.

Process Flow
Process Description
Fresh Flower Handling
Freshly harvested rose petals are processed within a few hours of harvesting to preserve highly volatile aromatic molecules.
Special hygienic conveying systems minimise flower damage.
Hydro Distillation
Rose petals are processed with purified water inside specially designed stainless steel hydro-distillation vessels.
Hydro distillation gently releases aromatic compounds while preserving delicate floral notes.
Cohobation Process
The condensed rose water is continuously recycled through the distillation system.
Advantages include:
- Increased Rose Otto recovery
- Higher aromatic intensity
- Reduced process losses
Steam Distillation
Optimised steam distillation completes extraction of remaining volatile components while minimising thermal degradation.
High-Efficiency Condensation
Special shell-and-tube condensers rapidly condense vapours while preserving delicate floral compounds.
Florentine Oil Separation
Automatic Florentine separators separate:
- Premium Rose Otto
- Premium Rose Water
Advanced oil separation minimises product loss.
Vacuum Oil Polishing
Rose oil undergoes vacuum polishing to remove moisture and improve clarity without affecting its delicate fragrance profile.
Quality Standardisation
Each production batch undergoes comprehensive analysis for:
- Citronellol
- Geraniol
- Nerol
- Phenyl Ethyl Alcohol
- Linalool
- Specific Gravity
- Refractive Index
- Optical Rotation
- Moisture
- GC-MS Fingerprint
