STiR coffee and tea 39 A highly efficient heat recovery system reduces energy costs by 20%.

Photo credit: PROBAT Smart Automation — Not Over-Automation To make the Cx70 more accessible to roasteries just starting out, the standard configuration has been set to a more basic level and is available in either manual/assisted or higher-automation configurations — allowing roasters to choose the level of process automation that matches their exact needs. "Now we can reach roasteries that simply want to roast coffee, but the machine is configurable to also meet the higher demands of customers seek- ing advanced technology, the highest level of automation, and greater energy efficiency," adds Weimer. PROBAT's industrial machine control software, ProCS M, addresses the growing demand for AI technical integration. "The Cx70 comes with ProCS M, PROBAT's tailor-made, web-based control system and user interface available across our entire product portfolio," explains Fichthorn. ProCS M offers a wide level of flexibility, allowing the Cx70 to run as a semiautomatic or fully automatic system. The operators can decide how much they themselves want to control or let the system control operations. "So it's very scalable and flexible," adds Fichthorn. The Reflex roasting feature allows the roaster to directly see how the ma- chine is operating. "The roaster can set their target profile, and the current profile runs against it," says Fichthorn. "The system automatically shows if there are deviations, and the control system immediately adjusts the necessary parameters." For roasters seeking more hands-on control, the advanced features can be disabled, and the machine can be operated manually. Best Total Cost of Ownership Designed to maximize overall equipment effectiveness (OEE), the Cx70 of- fers excellent total cost of ownership (TCO) rates. The all-electric roasting option, zero pneumatics, and optional partial exhaust air circulation all con- tribute to lower energy consumption. "From my point of view, the Cx70 is engi- neered for performance and designed for profit, with the best price-to-performance ratio on the market," says Weimer. An advanced heat recovery system recircu- lates emissions and reuses the thermal energy that would otherwise be exhausted into the atmo- sphere, reducing energy costs by 20%. "When we're talking about emission reduc- tion, we implemented highly efficient catalyzers to be ready for the global demand," adds Weimer. "There, we can configure the catalyzer to meet regional and country-specific requirements to re- duce emissions." The Cx70 is highly configurable but deliber- ately modular — customers pay only for the fea- tures they actually need. By enabling lower capi- tal expenditure (CapEx) and delivering reliability and proven PROBAT quality, the customer also profits from low operating expenses (OpEx) and, in the end, the Cx70 delivers an unbeatable price- to-performance ratio, "including return on invest- ment," adds Weimer. "This is the core benefit of the Cx70." Designed to Last The new-generation Cx70 drum roaster represents pragmatic industrial roasting: fewer compromises and unnecessary features, and a sharper focus on efficiency, reliability, and profitability — without abandoning roast quality or process transparency. "As our customers' needs evolve and their busi- nesses expand, the Cx70 is designed to grow and adapt with them for decades to come." The new Cx70 debuts at Hotelex in Shanghai, March 30-April 2, 2026. Visit PROBAT at booth C22 in hall 2.2 for live demonstrations and more information.
