Abstract:
Cheap and easy direct solar drying is still practiced by small farmers who mostly live in rural areas. This method results in slow drying and improper heating due to sub-optimal temperatures. This only relies on the ambient temperature which has an average of 32.26oC with a range of 29.38-33.88oC. In addition, small farmers need appropriate tools at affordable prices and materials that are easy to obtain on the market. For this reason, the research was carried out by thermally studying an indirect type solar dryer using a corrugated plate collector made of zinc material. The test results show that the ambient temperature can be increased by 34.54%. This increase was measured in the drying chamber without load with an average temperature of 49.29oC with a range of 38.20-56.84oC. With this condition, it is hoped that it can be applied in the post-harvest drying process for small farmers. In addition, dryers designed with local materials and readily available on the market have received a positive response from small farmers to speed up the food drying process.
