Abstract. The harvest is one of the most important activities in coffee crops; on the one hand, it provides employment opportunities for a large group of rural workers and on the other, it supplies mature fruits for the production of high quality coffee. In the present study, a device was designed and evaluated to assist in manual coffee harvesting, called Alfa, which employs a threetoothed blade beater, a DC motor powered by dry batteries and a system for receiving detached fruits. The research proceeded in two phases; in the first, the device was designed and built; in the second, an evaluation was carried out by using traditional manual collection as a comparison. The evaluations were developed in four locations: three experimental stations of Cenicafé and one private property. The variables studied were: number of fruits left on the ground after harvest, percentage of immature coffee in the harvested mass and yield. The device presented an operating time of four days without recharging, a weight less than four kg and an absence of technical failures; the operators had no problems with its use; and, in addition, it was possible to increase the yield of the operators by almost 70%; the percentage of immature coffee was between 4.5% and 3% and losses were between one and 19 fruits per site. |

La cosecha es una de las actividades más importantes en el cultivo de café; de un lado proporciona empleo a un amplio grupo de trabajadores rurales y de otro brinda frutos maduros que contribuyen a la obtención de café de alta calidad. En la investigación un equipo llamado Alfa fue diseñado y evaluado para asistir la cosecha manual del café. El equipo consistió de un impactador de tres paletas dentadas, un motor DC accionado por baterías secas y un sistema para recibir los frutos desprendidos. La investigación contó con dos fases; en la primera el equipo fue diseñado y construido, en la segunda una evaluación fue adelantada empleando como comparación la recolección manual tradicional. Las evaluaciones se realizaron en cuatro localidades, tres centros experimentales de Cenicafé y una finca particular. Las variables en estudio fueron: número de frutos dejados en el suelo luego de la cosecha, porcentaje de frutos verdes en el café cosechado y rendimiento. El equipo presentó un tiempo de operación de 4 días sin recarga, el peso fue inferior a 4 kg y no se presentaron fallas técnicas. Los operarios no manifestaron problemas con su uso y fue posible incrementar el rendimiento de los operarios hasta en 70%, el porcentaje de café verde estuvo entre 4,5 y 3% y pérdidas entre 1 y 19 frutos por sitio.application/pdfspaUniversidad Nacional de Colombiahttp://www.revistas.unal.edu.co/index.php/refame/article/view/47833Universidad Nacional de Colombia Revistas electrónicas UN Revista Facultad Nacional de Agronomía MedellínRevista Facultad Nacional de Agronomía MedellínMoreno Cárdenas, Edilson León and Oliveros Tascón, Carlos Eugenio and Álvarez Mejía, Fernando (2015) A Portable Device to Assist in the Harvest of Coffee in Colombia.
