Description -
The pendulum swing of the cage moves the bunches from the top of the cage and applies a graduated force as the bunches move down. Berries are separated from the stems by inertia (the force applied to the berries is stronger than berry/pedicel bond) and pass through the holes of the cage.
Berries and stems are collected on a roller sorter in order to remove all undesirable elements (vegetal parts…). User can easily make some adjustments according to the variety of grapes by setting the swing speed and the diameters of the cage’s holes.

Advantages -
Delta Oscillys ensures an efficient and qualitative destemming.
This new technology of destemming with a pendulum swing allows to:
•  Preserve the integrity of the berries (and thus limit the production of juice and vegetal characters),
•  Preserve the state of stems (no break, no grinding up),
•  Fully separate the grapes from stems,
•  Remove shot berries, verjus, dry grapes, unriped grapes which remains on the stems.

Results -
Delta Oscillys is five to ten times more qualitative than traditional destemmer. The residual vegetal parts are around 0,2% to 0,5% against 2% to 4,5% with a traditional destemmer.
