Cocoa bean winnower

In cocoa and chocolate manufacture, the dehulling of cocoa beans and preventing nib loss is an important step in order to ensure maximum yield. An optimally functioning dehulling plant ensures clean separation of the nibs and shell.

The winnower includes a screen raking system. The winnower processes the cracked beans and the outer husk is blown away. A series of screens sorts out the cracked cocoa beans into various sizes, now called cocoa nibs.

Bottom Line Technologies has built a small-scale winnower.

The winnower is suitable for artisan chocolate makers or for R&D.

Various bean breakers are offered for roasted or raw beans, as well as systems for loading beans into the breaker. The winnower has four screens, which can be specified by the user. A screen raking system maintains the flow of product through the screens. A vacuum system collects shell debris. Optional bean loaders are also available. The footprint of the winnower is approximately 3.7 x 1.2 m and it has a capacity of 150 kg/h.
