— Mill City Ovens is proud to announce its launch M seriesa modern line of automation-ready commercial coffee roasters, designed for the highest levels of precision and durability.
Now available in 6kg, 10kg and 20kg capacities, the M Series represents a breakthrough in specialty coffee technology, but also an crucial case study in overcoming the challenge of land-based production in today’s economic and political climate.
The M Series is the culmination of a five-year development cycle that aimed to bridge the gap between artisan coffee roasting and newfangled automation. Each machine is designed and built in Mill City’s state-of-the-art, 40,000-square-foot, solar-powered facility in northeast Minneapolis.
ENGINEERING EXCELLENCE AND INNOVATION

- Next-generation HMI with haptic control: The series debuts the RoastPATH touchscreen interface, featuring a specially programmed jog wheel with haptic feedback for intuitive, touch-sensitive precision of baking parameters.
- Acoustic Optimized Environment: Specially designed silent exhaust fans reduce ambient noise, improving the baking environment without sacrificing cooling power.
- Future-proof technology: All M Series roasters feature remote firmware upgradeability and a comprehensive remote diagnostics suite, enabling proactive maintenance and seamless addition of modern features.

After investing in massive equipment, specialized tooling and assembling a production team specializing in craftsmanship, the company now produces over 400 unique components for each roaster at its headquarters in Minneapolis.
