Evaluation of Two grapes Harvesting Machine with Horizontal and Vertical Shaking
AbstractHere the research results are presented whit the aim of comparing two types of grape harvesting machines, one using horizontal shaking (SO) and another using vertical shaking (SV). Both machines have been tested for the mechanical harvesting of Trebbiano Romagnolo trained by Casarsa and by GDC. The attention was focused on the extent of the vibrations transferred from the shaker, on the effects on the products and on the plants and on the final features of the wine. The results have shown differences between the two grape harvesting machines and to a lesser extent between the adjustments used with each machine. The extent and the duration of the vibrations transmitted have affected the mistreatment on the vegetation, the harvest's characteristics and the results of the enological transformation. Thanks to a closer interaction between the plant and the machine, the vertical shaking system has allowed for an overall better performance.
