Zerno Innovations – Variable Feed Rate Prebreaker
Zerno Prebreakers
Our prebreakers control the flow of your beans while cracking them shortly before they enter the grind chamber.
The Result
Regulating flow allows your burrs to be more effective and productive, resulting in lower frictional temperature, which prevents premature brewing of your grounds.
Why it matters
This method produces a more uniform & consistent grind with every brew. Finally, you are able to experience all of the subtle qualities that each bean has to offer.
ZERNO is driving prebreaker innovation
Our engineering team spent years of R & D testing methods to find the ideal combination of feed rate and burr rpm – with the goal of achieving control over particle size distribution and ensuring grind uniformity.
