Delta Oscillys Destemmer at pendulum swing

Delta Oscillys

Definition

•Destemming :

– Destemming is the action of separating berries from stems and pedicel which structures and supports the bunches.

Data

Berry weight (1 to 3 gr) Separation strength grape/pedicel (1 to 5 N = 100 to 500 gr)

Settings

• Cage’s holes diameter depends on:

– Grape diameter,

– Stem length and fragility,

– 3 available diameters, 20 mm, 25 mm and 30 mm.

• Speed :

Cage changing

Delta Oscillys range

•Preservation of berries integrity for almost all grapes varieties. •Limitation of juice production.

•No oxydation before tank storage = less vegetal tastes. •Simple product.

Delta Oscillys advantages

•Hand-picked and mechanical harvest

•Easy to adjust : Speed with wire control, cages type •Easy to clean : 30 mn (Oscillys 200)

•Maximum flow rate : up to 20 T/h according to grapes varieties (Oscillys 200)

Delta Vistalys R2

The Bucher Vaslin solution : Delta Vistalys

•Hand-picked grapes or mechanically harvested grapes previously destemmed and drained.

•Flow rate up to 10 t/h according to grapes variety and conditions of use.

•Delta Vistalys replaces between 10 and 20 sorters (Staff assignment to other essential functions in the winery).

Technological choices

•Ejection system : high frequency pneumatic electrovalves

– Approved system in food-processing and industry.

•Image analysis : automaton + video camera

– Colour linear video camera

– Directly usable images (no shadow, no saturation)

– Calculator specifically elaborated for a high-rate optic system: Image analysis and a fast decision-making device

Technological choices

•Kinetics of objects : Conveyor with nozzles

– Designing goal: 100% of objects are analyzed and sorted through the optic system

– High-speed, steady levels and straight driving. – Homogeneous spreading of objects over the

Background

• Controlled lighting : LED electroluminescent diodes - Adjusted enlighting intensity : qualitative optic restitution of

the object

- Long-lasting stability and long-lasting life

Delta Vistalys

• Vistalys is meant to wineries that are willing to :

– Valorize their crop thanks to accurate, repeating sorting parameters.

– Constitute qualitative batches (example: sorting of thrown berries on first separation).

– Better control crop conditions (ensured qualitative sorting). – Productivity gains.

– To take advantage of the flexibility of a tool available 24 hours a day, 7 days per week (ensured efficiency all day long)

Harvest

•Used on a big variety of vine on several continents (Pinot noir, Gamay, Syrah, Carignan, Cabernet Sauvignon, Cabernet Franc, Cabernet Franc, Cinsault, Sangiovese, Barolo, Merlot)

•Programs adapted for the manual grape harvest or the machine •Handling facilitated by the auto-learning

•The flows allowed by the optical sorting give:

– A bigger flexibility at the level of the contributions – The possibility of making several qualities of batches

What to do with ?

•For the users, that is used to work out white and rosé wines adapted to the new consumers’ needs : fresh, fruity, aromatic, easy to drink, colour stable (rosé) wines

How it works?

•Inertys makes it possible to completely avoid the contact between oxygen and the grape or musts throughout all pressing.

•Inertys preserves the grape flavour precursors and makes it

possible the winemaker to reveal 100% of the potential of its type of vine

Competitive advantages

•Inertys is patented

•Only system able to provide neutral gas to the press with a sufficient instantaneous flow

•100 % of the musts are protected •Low consumption of neutral gas

•Customers testimonies

– « Valorization of last pressing juices which makes profitable the installation more quickly»

– «Rosé and white wines adapted to export sales» – « A great aromatic richness »

– « Colour stable rosés »

– « Global winemaking process in reductive conditions »

•During the blind-tests tasting, the Inertys method is systematically recognized

•The users are convinced of the benefit of Inertys technology and became our best ambassadors

Presentation context

• This presentation was given as part of a workshop on grape and juice processing equipment convened by the Australian Wine Research Institute (AWRI) at the 15th

Australian Wine Industry Technical Conference in July 2013.

• The main intention of the workshop was to provide attendees with information on equipment that is new or unusual or that has not been widely used in Australia.

• This and the other presentations given were prepared by equipment suppliers, not by AWRI, and AWRI does not necessarily endorse the views presented. Before the purchase of any major winery equipment, AWRI recommends appropriate background investigations being undertaken; including visits to facilities already using similar equipment, consultation with independent experts and the performing of in-house trials.

• AWRI received no payment from suppliers for the inclusion of their equipment in the workshop.
