Winnowing system

Winnower

The two-stage crushing process in the Winnower delivers maximum yields in cocoa processing. High-capacity sieving with 3 to 7 sieve decks and integrated shell aspiration minimizes fines and gives you precise control for beans of any origin.

Key benefits

Swing-out aspiration box makes maintenance and cleaning easy
Lifting the aspiration box provides immediate access to the sieves, making sieve changes, cleaning and maintenance fast and simple.
Automatic parameterization for optimal product quality
Automatic parameterization (vacuum control) enables you to maintain efficient separation, regardless of varying product throughput or the condition of the sieves.
Optimized sieving system for efficient shelling
The sieve dimensions can be optimally matched to your production capacity to ensure efficient separation of your nibs from your shells.

Highlight features

Maximum total yield

Two-stage crushing principle for maximum total yield

A two-stage crushing process with two impact crushers allows you to precisely match the crushing intensity with the specific cocoa bean origin. The first stage crushes gently. The second stage crushes the unopened beans more robustly. You can precisely set the forces depending on the characteristics of the beans in each batch.

High winnowing efficiency

Choose the sieve decks to suit your production

You can select between three and seven sieve decks to suit your processing throughput: The compact winnowing systems have 3 sieve decks each, the medium sized ones offer 5 sieve decks and the high throughput ones incorporate 7 sieve decks each.

Tight control

Separation settings to suit your beans

Separation efficiency can be reproduced and optimized for each origin of beans by up to 9 measurement points and by making breaker speed adjustments.
