This destemming process operates without beater shaft nor rotative cage. It uses an ample swinging motion of the one or two cages to separate the grapes from the stems by inertia.
Thanks to the inertia effect, there are many advantages:
• Preserved integrity of the berries (and thus limited production of juice and vegetal characters)
• Preserved state of the stems (no break, no grinding up),
• Fully separation of the grapes from the stems
• Elimination of shot berries, verjus, dry grapes, unriped grapes which remains on the stems
Delta Oscillys operate within a throughput range of 3t/h to 20t/h* * depending on grapes varieties, condition and grapes nature
Grapes are introduced through the hopper and are progressively brought to the de-stemming speed rate without any impact. The cage and the mixer rotate in the same direction to prevent any shearing effects on the grapes.

Bucher Vaslin has developed a new destemming concept for superior protection of the most fragile grape varieties. The objective is to separate grape berries from MOG while keeping their integrity throughout the operation for a minimum juice release.
Output: 4 t/h depending on the grape variety, state of grapes and feeding mode.
