Ashwagandha Extraction Plant
Ashwagandha Extraction Plant
Ashwagandha (Withania somnifera) is India's most celebrated adaptogenic herb, valued for withanolides that support stress relief, cognitive function, and hormonal balance. Mechotech's ashwagandha extraction plants deliver standardized root extracts of 2.5%–10% withanolides by HPLC, meeting global pharmaceutical and nutraceutical quality requirements.
Mechotech engineers ashwagandha extraction plants using food-grade alcohol extraction followed by multi-stage purification to concentrate and standardize withanolide content. Our GMP-compliant plants feature SS 316L contact surfaces, vacuum evaporation for solvent recovery, and spray-drying capabilities. Plants are sized from pilot-scale to full industrial capacity with full automation and documentation support for regulatory compliance.
Manufacturing Process
Root Preparation
Dried ashwagandha roots are cleaned, size-reduced, and ground to 20–40 mesh powder. Moisture content is verified before extraction to ensure consistent yields.
Maceration & Extraction
Powdered root is macerated in food-grade ethanol-water mixture (70:30) in jacketed extraction vessels at controlled temperature. Multiple solvent washes maximize withanolide recovery.
Filtration
The extract is filtered through plate-and-frame and cartridge filters to remove all solid impurities, producing a clear, golden miscella.
Evaporation
The filtered miscella is concentrated in a falling-film evaporator under vacuum at below 60°C to preserve thermolabile withanolides while recovering 95%+ of solvent.
Spray Drying
The concentrated extract is spray-dried to a free-flowing powder with controlled moisture content (<5%). Excipients such as maltodextrin can be added for improved flowability.
Standardization & QC
Final extract is tested by HPLC for withanolide content, microbial load, heavy metals, and pesticide residues before release for commercial use.

Key Features
High Withanolide Yield
Optimized extraction parameters ensure maximum withanolide recovery, consistently delivering 2.5%–10% standardized extract with minimal batch variation.
Alcohol Recovery System
Integrated multi-effect evaporation and condensation systems recover over 95% of ethanol, reducing solvent costs and meeting environmental discharge norms.
Low-Temperature Processing
Vacuum evaporation below 60°C preserves the integrity of heat-sensitive withanolides, ensuring bioactive potency is maintained in the final extract.
GMP Documentation
Complete batch records, SOPs, cleaning validation, and equipment qualification documentation are provided to support WHO-GMP, US-FDA, and EU-GMP certification audits.
Spray Drying Integration
Optional in-line spray drying system converts concentrated liquid extract directly to free-flowing powder, reducing processing steps and handling losses.
