Solar dryer for agricultural produce with temperature control
Design, build and test an indirect solar dryer for local produce such as chillies, dates or mango slices, comparing drying rate and quality with open-sun drying.
Scope
- Size the collector and drying chamber from heat-transfer calculations.
- Add sensors and a small fan controller to keep temperature in the safe range.
- Measure moisture loss over time and compare with open-sun drying.
A practical, low-cost project with clear local relevance to Multan's agriculture.
