Laboratory winnowing system for cocoa beans
Efficiently crush cocoa beans and separate shells from nibs with precision and control, streamlining your pre-processing phase and enhancing product quality. Ideal for scaling operations or refining product formulations.

Crushes and Separates Cocoa Beans
The LAB Winnower from Bühler Group is designed for precision in cocoa processing, providing a compact solution for labs and small-scale production environments. It employs a frequency-controlled crusher and adjustable air classification to efficiently crush cocoa beans and separate nibs from shells, minimizing product fines and maximizing yield. Capable of processing up to 150 kg/h, this winnower is ideal for producing cocoa nibs, cocoa mass, and chocolate liquor. With its stainless steel construction, the LAB Winnower ensures cleanliness and meets high food safety standards. Its closed design reduces dust pollution, enhancing safety and maintenance ease. Equipped with sampling capabilities, it facilitates process optimization and quality control, integrating seamlessly into pilot and continuous operations within cocoa and chocolate processing industries.
