<p>The present invention relates to a machine suited to separate the seeds from the pulp and from the skin of preferably broken grapes from which the stalks have previously been removed. The machine comprises at least a couple of counter-rotating parallel shafts (2,3), from at least one of which at least a spiral-shaped rib (6,7) projects, said rib (6,7) necessarily delimiting a groove (8,9) which is spiral-shaped too; in case the ribs (6,7) are provided on both shafts (2,3) of the shaft couple, the ribs (6,7) and grooves (8,9) on one shaft have an opposite, symmetric design of those on the other shaft. Between the surface of a shaft (included the ribs that possibly projects from it) and the opposite surface of the other shaft of the same shaft couple, an opening (P) is formed that does not allow the seeds to fall down, but lets the pulp and skin of the grapes pass. <IMAGE></p> |
