Eureka Drogheria MCD4 85 Commercial Shop Grinder

85mm Burrs for High-Volume Commercial Service

The Drogheria MCD4 85 is Eureka's top-tier commercial espresso grinder, designed for high-traffic cafés and specialty coffee bars. The 85mm flat burrset provides the highest throughput in Eureka's lineup—grinding double shots in approximately 2 seconds or less depending on grind setting. The MCD4 designation indicates the fourth-generation doser-free electronic commercial platform.

Professional Installation

The Drogheria MCD4 85 is a commercial appliance intended for professional café installation. Place on a stable commercial bar counter with adequate clearance. The machine requires a dedicated outlet meeting its power specifications.

Digital Controls

The MCD4 features programmable single and double dose settings via the digital display, stepless micrometric grind adjustment via the rear bottom-burr knob, and ACE anti-static technology for clean consistent dosing. Dose counters and maintenance tracking are accessible through the display.

Programming for High-Volume Service

Set single and double dose times via the display. With 85mm burrs, doses complete extremely quickly—timing precision is critical. Use a calibrated scale to verify dose output and adjust grind time in small increments.

Grind Adjustment at Commercial Volume

At high daily volume, check your grind setting at least twice per shift—once before opening and once during peak hours. Burr heat and bean density changes throughout the day can affect extraction time. The Drogheria's grind adjustment should be made while the grinder is running for accurate calibration.

ACE System in High-Volume Environments

At 85mm and high RPM, the ACE anti-static system is especially valuable—it reduces grounds scatter at the high output velocity the 85mm burrs generate. Keep the ACE chute clean and clear for best dosing accuracy.

End-of-Shift Cleaning

After each service shift: brush the chute and portafilter fork area, remove grounds from the removable chute assembly (where applicable), and wipe the exterior. Empty the bean hopper if leaving overnight to prevent stale grounds.

Weekly Deep Clean

Run grinder cleaning tablets through the grinder weekly at commercial use levels. Remove and brush clean the burrs if accessible via the top burr access. Check the ACE anti-static system for grounds buildup at the chute exit.

Inconsistent Dose Weights

At 85mm speeds, small variations in grind density have amplified effects on dose weight consistency. Verify grind setting stability, ensure the hopper is adequately filled, and run cleaning tablets if burr oil buildup is suspected.

Machine Running Hot During Extended Service

The 85mm motor generates substantial heat during extended service. Ensure adequate ventilation around the grinder and allow brief natural cooling between extremely dense service periods. Contact Seattle Coffee Gear if the machine triggers a thermal shutoff during normal service.
