Ginger Extraction Plant
Ginger Extraction Plant
Ginger (Zingiber officinale) yields a rich oleoresin containing gingerols, shogaols, zingerone, and volatile essential oils, all with powerful digestive, anti-nausea, and anti-inflammatory properties. Mechotech manufactures dedicated ginger oleoresin and extract plants for the food, pharmaceutical, and nutraceutical sectors.
Mechotech's ginger extraction plants use optimized solvent extraction to yield ginger oleoresin standardized to 5%–15% total gingerols, and essential oil by steam distillation in separate or combined configurations. Our stainless-steel plants incorporate explosion-proof design, solvent recovery systems, and GMP documentation — delivering repeatable, high-purity ginger oleoresin for global export markets.
Manufacturing Process
Ginger Preparation
Dried ginger rhizomes are cleaned, inspected for moisture and quality, and ground to 20–60 mesh. Moisture content below 10% is ensured before extraction.
Solvent Extraction
Ground ginger is loaded into percolation or immersion extraction vessels. Acetone, ethanol, or hexane-ethanol mixtures are used to selectively extract pungent oleoresins and flavour compounds.
Miscella Filtration
The spice-laden solvent (miscella) is filtered through sparkler filters and polishing cartridges to achieve a clear, particulate-free extract solution.
Evaporation
The filtered miscella is concentrated in a wiped-film or falling-film evaporator under vacuum at 50–65°C, recovering over 95% of solvent while preserving pungent compounds.
Standardization
The crude oleoresin is tested by HPLC for total gingerol content and blended to the target specification (5%, 10%, or 15% total gingerols).
Packing & Storage
The finished oleoresin is filled into food-grade aluminium tins or HDPE drums under inert nitrogen atmosphere to prevent oxidation during storage and transit.
Applications
- Food flavouring and spice oleoresin supply
- Anti-nausea pharmaceutical preparations
- Digestive health nutraceutical capsules
- Beverage flavouring (ginger ale, health drinks)
- Bakery and confectionery flavour applications
- Cosmetic warming massage products
- Ayurvedic formulations for digestive disorders
- Sports nutrition anti-inflammatory supplements
Key Features
High Gingerol Recovery
Optimized solvent selection and extraction parameters ensure maximum gingerol and shogaol recovery with minimal thermal degradation.
Combined Oleoresin & Oil
Optional dual-mode configuration extracts both ginger essential oil (steam distillation) and ginger oleoresin (solvent extraction) from the same raw material batch.
Food-Grade Compliance
All wetted parts are SS 316L with food-grade seals and gaskets, meeting FSSAI, FDA 21 CFR, and EU Regulation 1334/2008 standards for food-grade oleoresin production.
Solvent Recovery
Multi-stage condensation and recovery system recycles over 95% of extraction solvent, reducing variable costs and meeting environmental norms.
Flexible Capacity
Plant configurations from 200 kg/batch to 5,000 kg/batch are available to match your raw material procurement and production schedule.
