Diedrich Roasters has launched the DR-140, a roaster designed to handle green coffee batches of 70 to 140 kilograms. The model completes the company's transition away from infrared burner systems in its gas-fired lineup.

Why it matters

The launch reflects Diedrich's move from its IR and CR roaster models to its DR generation, which now covers the company's gas-fired roasting equipment. For Idaho-based coffee producers and roasters, the update signals a shift toward newer, automated roasting platforms.

The DR-140 handles batches of 70-140 kilograms of green coffee and produces up to 560 kilograms (1,232 pounds) of coffee per hour. The source did not provide pricing or independent performance comparisons against the CR-140 it updates.

The players

Diedrich Roasters

Diedrich Roasters is a coffee roasting equipment manufacturer headquartered in Idaho that builds commercial gas-fired roasters for coffee producers.

The details

The DR-140 features redesigned insulated roasting drums, airflow systems, and water-quenching for controlled cooling, along with emergency cooling for the drum, cooler, cyclones, and chaff barrels. It runs on Diedrich's in-house control software built on Allen-Bradley controls and supports Cropster and Artisan for third-party roast logging.

• October 2025: DR-140 launched
• December 2025: DR-280 roaster launched
• 2021: DR generation introduced with the DR-25
• Early 2022: DR-3 introduced, replacing the IR-1 and IR-2.5

Roadmap

The DR-140 is the latest step in Diedrich's replacement of its CR-140 and infrared-burner roasters with the DR generation first introduced in 2021. The company has since launched the DR-3, DR-25, and DR-280 alongside the DR-140 as part of that transition.

Idaho coffee roasters and cafes weighing equipment upgrades now have a newer gas-fired option in the DR-140 to compare against existing machines. Buyers should expect that the DR-140 is designed for batch sizes of 70-140 kilograms, which fits mid-scale production rather than small craft roasting.

The takeaway

Roasters evaluating new equipment should weigh batch size and automation features against their production volume before deciding between the DR-140 and older CR-models. Comparing controls and data-logging compatibility with existing workflows can help avoid costly mismatches.
