Hacia la Mejora del Secado Mecánico del Café en Colombia

This work is a review and analysis of the state of art of mechanical technologies for the coffee drying and potential actions to increase the efficiency. Also, it describes the importance to use alcohol as fuel, which could be obtained from subproducts of the humid benefit process of the grain, pulp and mucilage; this could be an option to improve carbon dioxide and particles emissions in comparison with conventional mechanics drying systems in Colombia.
