Abstract: The inventive raisin or grape seed extractor is used for a product made of crushed and destemed raisins or grapes which are introduced in a fast-rotating perforated conical drum for pressing the product; and a worm screw which is arrange inside the drum and turns slightly slow for controlling the forwarding of the product which penetrates in the top part of a cylindrical perforated separation drum arranged on the same geometrical axis that the other drum which is slightly tilted with respect to a horizontal line and turns slowly, thereby passing the seeds through perforations. The treated product is removed through the lower end and a spout towards fermenting tanks, the seeds being removed through an opening by the worm screw. The term “raisin”, translated from French, is understood to be raisins or grapes in English.
