Z1 Upgrade Announcement - Toothed Medium Feed Auger

This is an improved iteration of the original Medium Feed Rate Prebreaker—This design includes added 'teeth' that initiate the prebreaking process & regulate the flow of beans through the grind channel. 

This improved design facilitates a more consistent feeding of beans into the burrs—This consistency results in a more predictable result with every use.

This improved auger design is now shipping on all Z1 orders, and is available at the Zerno Online Store.
