Process Description
Raw Material Preparation
High-quality turmeric rhizomes are cleaned, dried, and milled to an optimized particle size to maximize extraction efficiency.
Solvent Extraction
Prepared turmeric powder is processed in stainless steel extraction vessels using food-grade solvents under optimized temperature and pressure conditions.
The extraction process provides:
- High oleoresin recovery
- Excellent curcuminoid extraction
- Preservation of volatile oils
- Uniform extraction
- Reduced solvent consumption
Primary Filtration
The extract passes through pressure filtration systems to remove suspended particles while maintaining maximum oleoresin recovery.
Vacuum Evaporation
Clarified extract is concentrated under reduced pressure using energy-efficient vacuum evaporators.
Advantages include:
- Preservation of aroma compounds
- Lower thermal degradation
- Reduced steam consumption
- Better product stability
Solvent Recovery
The plant incorporates MECH O TECH LLP's advanced multi-stage solvent recovery system.
Recovered solvent is:
- Condensed
- Purified
- Stored
- Reused
Solvent recovery efficiency exceeds 98%, significantly reducing operating costs.
Polishing Filtration
Fine filtration removes residual impurities and enhances product clarity while maintaining natural color and flavor.
Standardization
Oleoresin is standardized according to customer specifications for:
- Curcuminoid Content
- Color Value
