Maintenance & Cleaning

The cleaning process for the EG-1 is easy.  The grind chamber can be opened, thoroughly cleaned and resealed in about 30 seconds. The top and bottom funnel caps form a clam shell grind chamber and are secured together using sets of strong rare earth (Neodymium) magnets. The caps easily snap off the front of the unit, providing the barista with complete and unobstructed access to the burr set and wiper system.

The upper dosing dish has also been designed to be easily removed for cleaning. Held in place by a pair of Neodymium magnets and a set of stainless steel pins, the dish can be quickly uncoupled from the grinder for a quick wipe down.

At the end of the shift, in the middle, or even when changing the beans, it’s fast and easy to clear the grinder of any lingering residue. Ease of cleaning offers more options for using different roasts in high volume environments or in other service situations such as cupping rooms or roasting labs.


Burr Alignment

A common complaint with commercial grinders is the inability to check or adjust burr alignment. In the majority of machines, burrs are buried deep inside the grinder which makes a visual or mechanical inspection impossible. If there is an issue, evidenced by uneven burr wear or inconsistent shots, manufactures don’t offer adjustment mechanisms to calibrate a burr set after assembly.

We designed the EG-1 to make it simple for the user to both verify and adjust burr alignment. Without the use of any tools, the EG-1 burr set is fully accessible in less than 20 seconds. Ease of access to the burr set facilitates both regular maintenance and daily cleaning. If necessary, adjustments to alignment can be made with a 4mm metric hex key in a matter of moments without having to disassemble the grinder.


Burr Replacement

We reinvented the burr mount to make this easier to do than with any other commercial coffee grinder. With a 4mm hex tool and 5 minutes spare time, you can swap and perfectly align your EG-1 burrs to any of our 3 burr options depending on the grind profile you are going after.
