Here the research results are presented for two 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 extent and duration of the vibrations, the mistreatment on the vegetation and the harvest’s characteristics were measured. Finally, an evaluation of the enological transformation was carried on. The results have shown differences between the two grape harvesting machines and to a lesser extent between the adjustments used with each machine. Considering the different conditions shown by the two vineyards, the vertical shaking system has allowed for an easier regulation thus for a better performance.

Abstract

Here the research results are presented for two 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 extent and duration of the vibrations, the mistreatment on the vegetation and the harvest’s characteristics were measured. Finally, an evaluation of the enological transformation was carried on. The results have shown differences between the two grape harvesting machines and to a lesser extent between the adjustments used with each machine. Considering the different conditions shown by the two vineyards, the vertical shaking system has allowed for an easier regulation thus for a better performance.
