This paper presents the development of a prototype for humidity and temperature control during coffee drying at the Institución Educativa Agropecuaria La Capilla (Cajibío - Cauca). The prototype was developed using electronic instrumentation and computer aided design. The designed control system allows for the drying process to be carried out automatically. A silo-type mechanical equipment was designed, with a total capacity for a 5 kg load, allowing for a reduction in the drying time as compared to manual drying. [ABSTRACT FROM AUTHOR]
