Diedrich Roasters launched the DR-140 in October, a commercial coffee roaster designed for green-coffee batches of 70 to 140 kilograms. The model updates the CR-140 and completes Diedrich’s move away from infrared burner systems in its gas-fired lineup; production status, pricing and delivery schedules were not reported.
Diedrich Roasters launched the DR-140 in October, adding a gas-fired commercial coffee roaster built for green-coffee batches of 70 to 140 kilograms and completing the company’s shift away from infrared burners across its gas-fired lineup. The new machine updates Diedrich’s CR-140 and is aimed at midsize and larger roasting operations.
Diedrich says the DR-140 can produce up to 560 kilograms (1,232 pounds) of roasted coffee per hour. The company describes the machine as a redesigned platform, with changes to heating and airflow, drum-speed controls and automation intended to give operators more control over roasting at larger batch sizes. Those performance and efficiency benefits are company claims; the launch report did not provide independent performance testing or comparative energy-use figures.
According to Diedrich, redesigned insulated drums and airflow systems manage the movement of heat and air through the coffee more precisely, supporting more predictable roast curves. The machine also has water-quenching systems for controlled cooling during roasting and emergency cooling of the drum, cooler, cyclones and chaff barrels.
The DR-140 uses Diedrich’s proprietary control software, built around Allen-Bradley controls. Customers can use the company’s in-house engineering and service teams, and the system supports third-party roast logging through Cropster and Artisan. Diedrich also offers access to factory-trained technicians and hands-on training at facilities in Idaho and Schaumburg, Illinois, according to the report.
A New Option for Mid-Scale Roasting
The DR-140 gives commercial roasters a new machine option between smaller specialty roasters and higher-capacity industrial equipment. Its stated batch range of 70 to 140 kilograms and maximum hourly output of up to 560 kilograms may suit companies seeking to scale production while retaining control over roast profiles. Actual output will depend on operating conditions and production practices; Diedrich’s stated maximum is not an independently verified result.
The launch also marks a product-line milestone. Diedrich says the DR-140 completes the move away from infrared burner systems in its gas-fired lineup, replacing the CR-140 with a DR-series platform. For existing customers, support arrangements matter too: the company says it will continue providing parts and service for older IR and CR machines, and that some newer components can be purchased as upgrades.

Diedrich’s Shift to DR Models
Diedrich began introducing its DR generation in 2021 with the DR-25, then launched the DR-3 in early 2022 to replace the IR-1 and IR-2.5. The company has since replaced the remaining infrared models in its specialty line with DR machines while moving its larger commercial equipment away from the CR designation.
The DR-140 follows the DR-280, which launched in December 2025. Diedrich CMO Launtia Taylor told Daily Coffee News that DR-280 customers over the past year included midsize and larger coffee and food manufacturers in the United States. Taylor cited one buyer operating two machines at one facility and another that ordered four. Those examples are company-reported customer activity, not overall sales figures.
“The DR-140 builds on the legacy of our CR-140 by introducing a completely optimized platform that bridges the gap between artisan-level precision and high-volume industrial throughput.”

Pricing and Delivery Details Pending
The launch report does not state the DR-140’s price, order availability, delivery timetable or how many units Diedrich expects to sell. It also provides no independent testing to quantify the claimed improvements in energy efficiency, roast consistency or process control compared with the CR-140.
Diedrich has described customer interest in the DR-280, but the report does not give sales totals for that model or disclose DR-140 orders. Its stated maximum hourly capacity is a manufacturer figure, and the production rate customers will achieve in practice remains unreported.
Orders and Operating Results
The next useful indicators will be the DR-140’s pricing and delivery information, along with customer installations and operating results. Those details could help roasting businesses compare the machine’s capacity and running costs with existing equipment. Diedrich has said it will continue parts and service support for IR and CR machines already in the field, but has not provided a timetable or further specifics about the availability of upgrade components.
