Abstract: An experimental set up has been developed to investigate the performance of natural convection solar dryer for drying of selected material. Measurements of total solar radiation on the plane of the collector, ambient temperature and humidity, air flow rate, temperature and relative humidity inside the dryer as well as solid’s moisture loss-in-weight data are employed to study the performance of the dryer. A data logger and a computer were employed for data acquisition. First, detailed diagnostic experiments were carried out with no drying material on the trays. Next, a number of experiments were conducted using potato slices. For all the test conditions, the material gets dried with system’s efficiency of 15.9%. The drying time compared to sun drying was reducing by about 19%. The protection of the dried material against direct sunshine, dust, and insects results better quality product.
