High-Output Grind-by-Weight or Grind-by-Time

The Wendougee RKONE-90B-T is a commercial espresso grinder built around 90 mm titanium-coated flat burrs and a brushless reduction motor. It is designed for cafés that need fast grinding, hands-free portafilter support and a choice between time-based and weight-based dosing.

Published output is approximately 8–9 grams per second, fast enough to reduce grinder queueing during a rush when the burrs, coffee and recipe are correctly matched. Electronic grind adjustment and saved profiles aim to make recipe changes repeatable. A straight outlet is designed to reduce retention and keep the dosing path easier to clean.

Workflow Features

  • 90 mm flat burrs: large cutting surface for commercial speed and consistency.
  • Titanium coating: intended to extend burr life under heavy use.
  • Grind by weight or time: choose the dosing method that fits the bar.
  • Automatic activation: starts grinding when the portafilter is placed in the fork.
  • Digital grind adjustment: controlled changes rather than a purely mechanical collar.
  • Brushless motor: high torque with reduced brush maintenance and noise.
  • Straight grounds path: intended to reduce retention and scatter.

Grind by Weight vs. Grind by Time

Time dosing is fast and familiar, but the delivered mass changes as coffee density, burr condition and grind setting change. Grind-by-weight measures the dose directly and can reduce day-to-day variance, though the weighing system still needs calibration and a clean, stable portafilter position. Many shops use weight mode for the main recipe and time mode as a fallback.

Who Should Choose It?

The RKONE-90B-T is aimed at busy espresso bars where dosing speed, repeatability and electronic adjustment justify a large commercial grinder. A low-volume restaurant may not benefit from the size and complexity. For a full comparison, browse our commercial grinder collection.

Dial-In and Cleaning

Season new burrs, calibrate the weighing system and dial in with the actual coffee after warm-up. Record target dose, beverage yield and shot time. Purge only what is necessary after adjustment, brush the chute daily, keep the fork and scale contact points clean, and follow the manual before removing burrs or panels.

Frequently Asked Questions

Does grind-by-weight eliminate the need to check doses?

No. Verify doses with an independent scale during setup and periodically through the day.

Is 8–9 g/s guaranteed?

No. Output changes with burr condition, roast level and fineness. Treat the published rate as a reference.

Can it grind for filter coffee?

It is presented as a commercial espresso grinder. Confirm adjustment range and burr geometry before buying it for another brew method.

How many recipes can it store?

Published regional material references saved profiles, but the exact count and firmware behavior should be confirmed for the North American version.

What electrical outlet is required?

Wait for the certified North American cut sheet; do not wire from an overseas specification.

Great customer service! Joe worked with me from purchasing a grinder to ultimately returning and changing to a different grinder. It’s a tough decision buying without seeing or using and the fact that a business is willing to work with their customers goes a long way with me.
