Forced-Convection Solar Dryer for Agricultural Produce
Approx. component budget: Rs. 10,000 - 14,000
Objective
Study drying rate and drying time of a product (tomato, chilli, banana) vs open-sun drying, and find collector efficiency.
What you will build
Solar air collector (GI absorber + glass), drying chamber with trays, DC fan run by a small solar panel, temperature/humidity sensors and a weighing scale.
Results you can expect
- Moisture content vs time curves
- % reduction in drying time
- Collector efficiency
What you will learn
Heat and mass transfer, renewable energy and practical agri-engineering with a real-world use case.
Tools and notes
Excel/Python. Results depend on weather, so test on several days.
Resume points from this project
- Built and tested Forced-Convection Solar Dryer for Agricultural Produce; objective: study the drying rate and drying time of a product (tomato, chilli or banana) vs open-sun drying, and find the collector efficiency.
- Measured and analysed moisture content vs time curves and Reduction in drying time (%); wrote the report and presented the results in a viva. Add your own numbers: [x].
Replace [x] with your own measured results. Write only what you really did.
