12. Packaging
Description: Flour is weighed and packed into bags.
Equipment: Automated weighing and bagging machines.
13. Quality Control
Checkpoints:
- Moisture content (after conditioning).
- Purity (post-cleaning).
- Particle size (during sifting).
- Nutritional compliance (post-fortification).
Equipment: Moisture meters, lab sieves, spectrophotometers.
Flow Diagram Summary:
Raw Maize → Cleaning → Conditioning → Degermination → Milling → Sifting → Grading → Fortification → Packaging.
By-Products: Germ, bran, and residual coarse particles (recycled or sold).
Key Notes:
- The process is a dry milling method, optimized for 50-ton/day capacity.
- Sifting stages ensure high extraction rates (≈70-80% flour yield).
- Modular design allows scalability and customization (e.g., fortification).
