Abstract
Se diseñó y evaluó un sistema que evite incorporar al bulto de caña se azúcar (Saccharum spp) en el alce mecanizado impurezas tales como piedras, tierra y rastrojos. El principio es que el cortador debe colocar los tallos de caña sobre una estructura metálica de manera que ésta no esté en contacto con el suelo (separada a unos 20 cm) y además le de forma al bulto para que la “araña” o “jaiba” de la alzadora lo pueda tomar en una sola acción. Para determinar la efectividad del sistema, durante la zafra 2007-2008 en la zona de abasto del ingenio Central Motzorongo, se evaluaron dos aspectos, el rendimiento del cortador y porcentaje de materia extraña acarreada. Los resultados sometidos al análisis de varianza permiten aseverar que el sistema de contenedores es superior al tradicional al reducir o eliminar la tierra y piedras y con ello aumentar el beneficio económico y de operación. Se recomienda continuar la generalización a todas las zonas de abasto con condiciones similares a la del estudio.
