Abstract
These study relates to coffee dryers sourced from solar energy, the main objective of these experiements are make solar drying tools more effective, save time, and get good quality coffee beans, so that they can be received by the community. The parameters that are used in this combustion are temperature, rh, sun intensity, weight, and Mr. the results obtained are that the temperature can vary between 40-60°C, with a maximum rh is 5%, weighing 4.291 kg, and finally getting the drying rate. The main conclusion are these temperatures are very suitable for drying coffee beans, the higher the intensity of solar radiation will reduce the drying Moisture ratio and can be reduce of mass coffee.
