Solar dryer is an economical way of drying various agricultural products. The limitation of solar drying is that it available only during sunshine hours. An integration of phase change material (PCM) is one of the options to extend drying process after sunshine hours since it store heat in form of latent heat. In this work, an indirect, forced convection, single pass, batch type solar dryer with phase change material (PCM) was designed, constructed and experimentally investigated. Solar collector consists of rectangular pipe type absorber and it works as a PCM chamber. The experiments are carried out on solar dryer test rig under various loads, with PCM and without PCM. The main aim to carry out experiments is that to investigate the feasibility of using a solar dryer with PCM to store the solar energy in form of heat during the daytime, and to release it during the night or cloudy weather. Experiments were conducted to evaluate increments in cycle time, increment in collector’s and dryer’s efficiencies.
