Grape crop sorting table has zones with two different mesh sizes to separate unripe fruit, mature grapes and leaves/stalks

摘要

The sorting table consists of at least one surface (18) over which the harvested grape crop flows, made up of zones (28, 32) with two different mesh sizes for separating smaller elements (30) such as unripe fruit, and larger ones (16) i.e. mature grapes. In the second zone the mesh size increases progressively between its beginning and its end sections, which slope down and up respectively. The table is also equipped with a vibration generator for its upper surface (18) that causes the grapes to move along it, and a compressed air system for blowing away the lightest components (34) such as leaves and stems. The grapes can be delivered to the table through a hopper (24) fed by a pump or elevator.
