Process Flow
Process Description
Raw Material Preparation
Neem seeds and leaves are thoroughly cleaned, sorted, and milled to the optimum particle size to maximise extraction efficiency while preserving heat-sensitive phytochemicals.
Cold Pressing (Optional)
Where Neem Oil production is required, cleaned neem seeds are processed through cold pressing before solvent extraction of the residual oil cake.
Advantages include:
- Premium cold-pressed neem oil
- Higher overall oil recovery
- Better utilisation of raw materials
- Designed to support process economics
Solvent Extraction
Prepared material undergoes extraction using food-grade or pharmaceutical-grade solvents under optimised operating conditions.
The extraction process provides:
- High azadirachtin recovery
- Uniform extraction efficiency
- Reduced oxidation
- Consistent product quality
Filtration
The crude extract passes through pressure filtration systems to remove suspended solids before downstream processing.
Vacuum Solvent Recovery
The clarified extract enters high-efficiency vacuum evaporators where extraction solvent is recovered, condensed, purified, and reused.
Benefits include:
- Designed for efficient operation
- Environmental sustainability
- Enhanced process safety
- High product purity
Vacuum Concentration
The extract is concentrated under low-temperature vacuum conditions to preserve thermolabile active compounds.
Membrane Clarification
Microfiltration and ultrafiltration systems improve product clarity while retaining valuable phytochemicals.
Advantages include:
- Improved purity
- Better colour
- Enhanced stability
- Lower product losses
Purification & Standardisation
Advanced purification systems enrich azadirachtin and standardise the finished extract.
Typical specifications include:
- Azadirachtin Content
- Nimbin
- Salannin
- Limonoids
- Moisture
- Bulk Density
- Particle Size
Spray Drying
The purified extract is converted into a stable free-flowing powder suitable for pharmaceutical, nutraceutical, and agricultural applications.
Quality Standardisation
Each production batch is analysed for:
- Azadirachtin
- Nimbin
- Salannin
- Limonoids
- Moisture
- Residual Solvent
- Heavy Metals
- Pesticide Residues
- Microbial Limits
- Particle Size
- Bulk Density
