Petiole: It is the small woody stem which is more than 3 mm long connecting the grape to the bunch twig. Petiole Stem Remover is a machine used to cut the stems of the product placed through the upper part without damaging the product, thanks to the axe blades located inside. It is mostly used for raisins. Optional alternatives are available as double and single. In cases where dry petiole stem removing is not required, the by-pass oscillator located at the upper part can easily be used.
