Designing the grind
For Bühler, we designed the NOVA S Ball Mill, a cocoa grinding platform that refines roasted cocoa nibs into particles smaller than the tongue can perceive, creating the smooth melt that defines fine chocolate. The formal vocabulary translates Bühler’s brand DNA into an industrial machine optimized for efficient Swiss manufacturing, hygienic food processing, and safe operation in demanding production environments worldwide.






The machine architecture is divided into two structural zones: a food-processing zone and a drive zone. This clear separation supports the requirements of hygienic design. A vertical stand formally and functionally separates the aggregate section from the process area.

Clean joint lines structure and rhythmize the large surfaces. The design relies primarily on two-dimensional sheet-metal developments, avoiding complex welded constructions. This approach reduces manufacturing effort and allows the machine to be produced in Switzerland as efficiently as possible.
