20251ME6: Solar seed dryer
Brief Description & Functionality
A Solar Seed Dryer is an eco-friendly, non-electric drying system used to remove moisture from agricultural seeds using solar energy. It ensures proper seed preservation, increases shelf life, and prevents fungal growth—especially in rural farming, seed banks, and post-harvest processing.
- Reduces seed loss due to mold and moisture
- Enables clean, renewable drying without electricity
- Essential for sustainable agriculture, especially in off-grid areas
- Protects germination potential by drying at controlled temperatures
How it works:
The system works by converting solar energy into thermal energy, which is used to dry seeds:
- Transparent cover (glass or polycarbonate) traps solar heat inside
- Black absorber surface converts sunlight into heat
- Heated air rises inside the drying chamber, carrying moisture away
- Vents or fans allow hot humid air to exit and fresh air to enter
- Seeds placed on perforated trays dry uniformly under controlled airflow
How Equipment Works
| Component | Description |
|---|---|
| Solar Collector Panel | Transparent surface traps solar heat inside drying chamber |
| Drying Chamber | Houses seed trays arranged for uniform airflow |
| Ventilation Holes / Fan | Allows moist air to escape; fan increases efficiency |
| Seed Trays | Mesh trays allow airflow from below |
| Frame & Insulation | Built using wood, metal, or plastic for structure and heat retention |
| Optional Temperature Sensor | Ensures heat doesn’t exceed safe seed-drying limits |
