“ROLLTEC” roller sorting table

ROLLTEC is a selection table with rollers conceived for the separation of the grape berries from all waste parts, such as leaf stems, leaves, stems, small not ripe or dry grapes, and other foreign bodies. ROLLTEC is equipped with a vibrating hopper in the machine inlet that spreads the product evenly on the separation rollers. The series of rollers is subdivided in two parts; on the first section there are six rotating shafts with rollers, having a profile specially conceived to eliminate small not ripe grapes, dry grapes,.residues, etc; on the second section there are nineteen rotating shafts with rollers, having a profile suitable to let the whole grapes drop below, retaining above the stems and the leaf stems until they are eliminated to the discharge conveyor. The spacing between rollers is easily adjustable in a continuous manner through special handles placed outside the machine. The adjustment of the first series of rollers is independent from the second, so the work can ideally adapted either for the separation of the grape waste or for the whole grape screen.
