Diedrich Roasters launched the DR-140 in October, a commercial coffee roaster designed for batches of 70 to 140 kilograms. The model updates the CR-140 and completes Diedrich’s shift away from infrared burner systems in its gas-fired lineup; production and support arrangements for older machines remain relevant to existing owners.
Diedrich Roasters launched the DR-140 in October, adding a gas-fired commercial roaster designed for 70- to 140-kilogram green-coffee batches and completing the company’s transition away from infrared burners in its gas-fired lineup. The Idaho-based manufacturer describes the machine as an update to its CR-140, with redesigned heating and airflow systems, more drum-speed control and expanded automation aimed at commercial operators.
Diedrich says the DR-140 can produce up to 560 kilograms (1,232 pounds) of coffee per hour. That is the manufacturer’s stated maximum output; the report does not provide operating conditions or independent performance testing for the figure. The roaster’s stated batch range places it between smaller specialty-scale machines and higher-capacity production equipment.
The design includes insulated roasting drums and revised airflow systems, which Diedrich told Daily Coffee News are intended to give operators more control over heat and air moving through the beans. The company said these changes can support more predictable roast curves at larger batch sizes. 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 in-house control software and Allen-Bradley controls. It also supports Cropster and Artisan for third-party roast logging. Diedrich says programming and support are handled by its engineering and service teams, with factory-trained technicians and hands-on training available through facilities in Idaho and Schaumburg, Illinois.
A New Option for Mid-Scale Production
The DR-140 gives commercial roasters seeking a machine for 70- to 140-kilogram batches a new option within Diedrich’s updated equipment range. Its stated capacity and hourly output may be relevant to businesses scaling production, including coffee roasters and food manufacturers. The company’s claims about improved control and efficiency describe design aims, rather than independently verified gains.
For existing Diedrich customers, the shift also marks a change in the company’s current product lineup. Diedrich has ended production of the older IR and CR models, but says it will continue providing parts and service for machines already in use. Select newer components can also be installed as upgrades on some existing IR and CR machines, according to the company.

Diedrich’s Move to DR Models
Diedrich began introducing its DR generation in 2021 with the DR-25. The DR-3 followed in early 2022, replacing the IR-1 and IR-2.5, while the company subsequently replaced remaining infrared models in its specialty line and began moving its larger commercial equipment away from the CR designation.
The DR-140 follows the DR-280, launched in December 2025. Together, the two models represent the latest part of that commercial-line change. Diedrich CMO Launtia Taylor told Daily Coffee News that the DR-280 had attracted orders from midsize and larger commercial coffee and food manufacturers in the United States, including multi-machine orders. Those examples refer to the DR-280, not sales of the newly launched DR-140.
“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.”

Performance and Sales Details Pending
The available report does not give the DR-140’s price, delivery schedule, order volume or confirmed customer list. It also does not provide independent measurements comparing energy use, roast consistency or throughput with the CR-140. Diedrich’s stated maximum output and descriptions of process improvements should be read as company-provided information, not as independently tested results.
Details about the extent of compatibility between newer components and older IR and CR machines are also limited: Diedrich says select upgrades are available but does not identify every eligible model or component in the report. The company’s continued service commitment is reported, but no timeframe or terms are specified.
Orders and Customer Results
The next indicators will be delivery information, customer installations and operating results from DR-140 users. Those details could show how the machine performs across its stated batch range and whether its design features translate into measurable changes for commercial operators. Diedrich has not provided a specific date for customer deployments or public performance data in the source report.
Existing IR and CR owners can contact Diedrich about parts, service and whether their equipment qualifies for a component upgrade. For prospective buyers, pricing, availability and service arrangements are points to confirm directly with the manufacturer before making purchasing plans.
