Introducing the fantastic Atom grinder by Eureka. Featuring long lasting titanium flat burrs. Stepless grinding adjustment gives you an “infinite” range of settings which allow you to really fine tune your grind to your espresso machine. Turn clockwise for a finer grind and counterclockwise for a coarser grind. The adjustment knob is located on the top right of the grinder, underneath the bean hopper. This helps keep the overall width of the Eureka Atom low compared to other grinders that have it on the side. This also protects it from hitting against other equipment.
The bean hopper sits comfortably on top of the grinder. There is a rubber neck guard which helps protect the neck of the bean hopper from cracking. The set screw secures the hopper to the grinder. Prevents users from quickly removing the hopper, spilling beans everywhere. Convenient finger guard prevents users from “accidentally” putting their fingers in the grinding burrs. A door near the bottom of the hopper can be pushed in to close the opening. This allows you to remove the hopper with beans inside so you can easily change the beans. There will be some beans already passed in the burrs which will have to be ground out first before removing the hopper.
The Atom also has an integrated portafilter fork used mainly for espresso grinding. The distance from the portafilter fork to the coffee chute is approximately 2.5″. There is a built-in lip that helps hold most portafilters in place. The distance from the portafilter fork to the lip is approximately 1.5″. The fork can be adjusted up and down by loosening the holding screw with the included Allen key.
The Atom also has easy to use electronic controls and time based grinding. The “1-cup” mode can adjust from 0.5 seconds to 25 seconds. The “2-cup” mode can adjust from 0.5 seconds to 35 seconds. You can adjust the time by 0.1 second increments. The semi-automatic mode tracks the time from start to stop. When semi-automatic dosing, the display switches to a picture of a grinding burr with a timer in the center. It will count up by 0.1 second increments until you stop. When electronic dosing, the screen will highlight whether you select “1-cup” or “2-cup”. The timer will count down when you start the grinding cycle.

- Order processing can take up to 48 hours (typically much sooner).
