Increasing of the Particle Size of Chopped Arundo for a Better Storage (original) (raw)

European Biomass Conference and Exhibition Proceedings, 2015

Abstract

Giant reed (Arundo donax L.) is currently harvested using the common self-propelled forage harvesters (SPFH). Often the product presents a distribution skewed towards the finer particles that can negatively influence the qualitative traits of the fuel and the efficiency of power plants. The Consiglio per la Ricerca in Agricoltura e l'Analisi Economica-Unità di Ingegneria Agraria, in collaboration with Spapperi Ltd, has designed and developed a prototype for cutting and sectioning the Arundo plants in order to produce a higher proportion of chips longer than the ones obtainable from a forage harvester. A study has been conducted to compare the characteristics of the product obtained from the prototype or from a SPFH. The percentage of the finest particle was statistically reduced in the prototype's product. At the same time, the fraction ranging from 6.3 to 12.5 mm arose of about five-to ten-fold. The first results show that the lengthening of the particle size is attainable.
