Executive Summary
A nutraceutical manufacturer required a turnkey extraction facility to manufacture premium Moringa Leaf Extract standardised for Polyphenols, Flavonoids, Chlorophyll, Antioxidants, and Natural Phytochemicals. The facility was intended to serve the rapidly growing global markets for dietary supplements, functional foods, beverages, pharmaceuticals, and cosmetics.
Mechotech successfully designed, engineered, manufactured, supplied, installed, and commissioned a Moringa Leaf Extraction Plant integrating advanced hydro-alcoholic extraction, membrane clarification, purification, vacuum concentration, solvent recovery, spray drying, and fully automated PLC-SCADA control systems.
Customer Background
The customer supplies botanical ingredients to nutraceutical companies, functional food manufacturers, pharmaceutical industries, cosmetic manufacturers, herbal supplement companies, and international ingredient traders. Growing worldwide demand for natural superfoods required the customer to establish a modern GMP-oriented extraction facility with higher productivity and international quality standards.
Customer Challenges
Prior to modernisation, the customer encountered several manufacturing limitations:
- Low extraction efficiency
- Chlorophyll degradation during processing
- Oxidation of bioactive compounds
- High solvent and energy consumption
- Inconsistent polyphenol content
- Manual process control
- Variable product quality
- Difficulty meeting export specifications
- Limited production capacity
Project Objectives
The customer required a plant capable of:
- Processing 10 MT/day of Moringa Leaves
- Producing standardised Moringa Extract
- Preserving chlorophyll and antioxidants
- Maximising flavonoid recovery
- Recovering extraction solvent for reuse
- Reducing operating costs
- Documentation to support the customer's quality and regulatory qualification
- Allowing future expansion

Process Description
Raw Material Preparation
Fresh or dried Moringa leaves are cleaned, inspected, and milled under controlled conditions to maximise extraction efficiency while preserving valuable nutrients.
Hydro-Alcoholic Extraction
Prepared leaves are processed in stainless steel extraction vessels using optimised hydro-alcoholic solvent systems.
The process ensures:
- High extraction efficiency
- Reduced oxidation
- Uniform batch quality
Primary Filtration
Extract is clarified through pressure filtration systems that efficiently remove suspended solids while retaining valuable phytochemicals.
Membrane Clarification
Cross-flow membrane filtration further improves product clarity by removing fine particulates without damaging sensitive bioactive compounds.
Benefits include:
- Improved clarity
- Better stability
- Reduced downstream load
- Higher product purity
Vacuum Concentration
The clarified extract is concentrated under vacuum using multi-effect evaporators.
Advantages include:
- Preservation of heat-sensitive nutrients
- Reduced steam consumption
- Better product stability
- Improved concentration efficiency
Purification
Advanced purification systems remove unwanted pigments, fibres, and insoluble impurities while enriching nutritionally valuable compounds.
Solvent Recovery
The closed-loop solvent recovery system recovers extraction solvent, supporting solvent reuse.
Recovered solvent is:
- Condensed
- Purified
- Recycled
- Reused in production
Spray Drying
Concentrated extract is converted into a premium-quality powder using controlled spray drying.
The finished product exhibits:
- High solubility
- Low moisture content
- High antioxidant activity
Blending & Standardisation
Finished extract is blended and standardised according to customer specifications before packaging.
