This paper presents the design of an experimental solar assisted dryer for palm oil fronds. The system consists of collector, a dryer, an auxiliary burner and a fan. The collector is of the double-pass configuration with porous media in the lower channel. The dryer is of the batch type where hot air introduced from the bottom. The size of the collector is 120 cm width and 240 cm in length. The upper and lower channels are adjustable for optimal operations. The size of the dryer is 100 cm width, 100 cm long and 80 cm in height. The project is funded by the Malaysian government and will be carried out at the Solar Energy Research Park University Kebangsaan Malaysia, Bangi.
