Developing a solar dryer for coffee

Drying is a critical aspect of coffee processing, since the quality and price of the coffee beans depend on how dry they are and also the way in which they have been dried. Even though coffee has been cultivated for decades the technologies used for drying are limited. In 2001 El Colegio de la Frontera Sur (ECOSUR) initiated a participatory research process to develop a solar coffee dryer with a group of organic coffee producers in Tziscan, Chiapas, Mexico
