Process Description
Raw Material Preparation
Premium dried ginger rhizomes are cleaned, inspected, and milled to the optimum particle size to maximise extraction efficiency while preserving valuable phytochemicals.
Solvent Extraction
Ground ginger is extracted in stainless steel extractors using carefully controlled food-grade solvent systems.
The extraction process ensures:
- High oleoresin recovery
- Preservation of volatile oils
- Reduced solvent usage
- Consistent batch quality
Primary Filtration
Pressure filtration removes suspended solids while retaining valuable oleoresin and aromatic compounds.
Vacuum Concentration
Clarified extract is concentrated under reduced pressure using multi-effect vacuum evaporators.
Benefits include:
- Low-temperature processing
- Minimal thermal degradation
- Preservation of aroma
- Reduced steam consumption
Solvent Recovery
Mechotech's advanced closed-loop solvent recovery system efficiently recovers the extraction solvent.
Recovered solvent is:
- Condensed
- Purified
- Recycled
- Reused
This significantly reduces production costs and environmental impact.
Aroma Recovery
A dedicated aroma recovery section captures valuable volatile compounds that contribute to ginger's distinctive flavour and fragrance.
Advantages include:
- Enhanced product quality
- Higher market value
- Improved flavour consistency
Polishing Filtration
Final polishing filtration removes trace impurities while preserving active compounds and natural flavour characteristics.
Product Standardisation
Finished products are standardised for:
- Gingerol Content
- Shogaol Content
- Volatile Oil Content
- Viscosity
- Moisture
- Residual Solvent Limits
