Abstract: Preservation of farm produce is one of the major problems faced by farmer in the developing nations of the world. A lot of farm produce perish before reaching the final consumer due to inadequate preservation method in these countries. These countries do not have constant power supply and technology to process there farm produce which will help make it last longer. They result in sun drying which is not efficient due to unsteady nature of the solar radiation. This work focused on using solar dryer to preserve tomatoes in developing countries. The experiment was done in University of Nigeria, Nsukka during the winter period to ensure that solar radiation was steady and to get a better result. The experiment showed that solar dryer could be used to preserve tomatoes produced in developing countries and as well make it reach the final consumers in good condition. The maximum atmospheric temperature recorded during the experiment was 31°C. The result achieved weight reduction of tomatoes used in the experiment from 30Kg to 4.5Kg.
