| Abstract | Preliminary investigation were .undertaken to evaluate the performance of inexpensive tubular type solar collectors using tin and black plastic material to heat the air for the application of grain drying. Black plastic pipe and blackened tin pipe equal in diameter and length were tested for their performance as air heaters under different solar intensities and with different air-flow rates. A maximum temperature rise of about 20°c above ambient was recorded in 24.4 meter long 30.48 cm in diameter pipe when airflow was 11.73 cubic meter per minute and subjected to flux intensities of 1.5 cal per sq. cm per min. Performance was improved by connecting the pipes in parallel instead of connecting in series. The results of comparison of drying of paddy with solar heated air and natural air were strongly in favour of solar heated air drying. |
