Solar Stone Flour Mill
Solar-powered stone grinding that turns grain into flour without grid power.
What is it?
A stone flour mill driven by a solar-powered motor, so grain can be ground on site during daylight hours without relying on the grid or diesel.
What problem does it solve?
- Grinding depends on unreliable grid power
- Cost of hauling grain to a distant mill
Who is it for?
- Farmer producer organisations
- Village flour mills
- Self-help group enterprises
How does it work?
Solar panels drive a motor that turns the grinding stones; output is highest in the middle of the day, so grinding is planned around sunshine.
Benefits
- No electricity bill for grinding
- No diesel or generator cost
- Grinding stays in the village
Limitations and trade-offs
- Throughput limited by available solar capacity
- Needs shaded storage for grain and flour
- Backup needed for cloudy-day demand
