With exclusive ElectroFlame® technology and smart Heat Management Software, it pairs a powerful electric burner with a ceramic drum housing, ensuring a superior roasting experience and cup profile.
The Stingray is an electric coffee roaster, engineered to deliver exceptionally consistent roasts with the power of innovation. Featuring our exclusive ElectroFlame® technology and smart Heat Management Software, the Stingray revolutionizes the roasting process by pairing a high-performance electric burner with a meticulously designed ceramic drum housing.
At the heart of the Stingray is ElectroFlame®, a breakthrough in electric roasting. This high-performance electric burner, housed within a custom ceramic drum, ensures precise control over heat distribution. The fully insulated chamber operates at sub-atmospheric pressure, creating an environment for exceptionally consistent roasts. With the Stingray, roastmasters have complete control over the roast profile, enabling them to bring out the full spectrum of flavors and aromas from every batch.
The Stingray integrates seamlessly with the Commercial Avirnaki—a fully electric smoke elimination system designed to eliminate harmful emissions like CO and NOx. Operating without reliance on fossil fuels, this system ensures a cleaner, more sustainable roasting process.
The Stingray E7 combines the benefits of conduction and convection, utilizing high-pressure airflow to precisely direct heat during the roasting process. This innovative approach ensures smooth, controlled, and precise roasting, resulting in coffee that’s clean, complex, and rich, free from undesirable aftertastes.
Optimizing thermodynamics and heat preservation, the Stingray delivers high performance while minimizing energy consumption. With a powerful, efficient burner, the machine ensures long-term, reliable performance, all while using less energy than traditional methods.
Built with stringent safety standards, the Stingray features multiple built-in safety mechanisms, including a sub-atmospheric chamber that prevents harmful emissions from escaping. Coffee-Tech Engineering ensures a safe, efficient, and sustainable roasting environment for both operators and the planet.
