Technology
Meet ElectroFlame: Electric roasting redefined.
Introducing ElectroFlame technology, a breakthrough that brings electric roasting to a new level. Engineered to preserve the distinguished CTE cup profile, ElectroFlame combines a high-performance electric burner, housed within a custom-designed ceramic drum housing.
With a fully insulated chamber, the drum operates at sub-atmospheric pressure, ensuring exceptionally consistent roasting.
With the Stingray, roast masters gain complete precise control over the profile, enabling every roasting style, and delivering the entire spectrum of flavor and aroma.
Electric Smokeless Roasting
A fully electric Smokeless System: Zero Emissions, Maximum Sustainability.
For a truly sustainable roasting experience, the Stingray integrates seamlessly with the Commercial Avirnaki—a fully electric smoke elimination system designed for maximum efficiency and durability.
Providing a cleaner, more efficient alternative to afterburners, the Avirnaki operates with zero reliance on fossil fuels while completely eliminating harmful emissions like CO and NOx.
Heat Transfer Method
The best of conduction and convection: optimized for precision and control.
The Stingray E7 is a revolutionary conductive roasting system that utilizes an efficient, low-volume at high-pressure airflow to precisely direct heat within the roasting process.
This innovative approach balances the benefits of conduction and convection, ensuring a smooth, controlled, and precise roasting process.
The result? coffee that is exceptionally rich, clean, complex, and well-developed, free from excessive wood taste, smog, or cereal-like notes.
Efficiency
Optimizing Roasting Efficiency Through Thermodynamics and Heat Preservation.
The Stingray is designed for unmatched energy efficiency, with integrating state-of-the-art thermodynamic heat preservation and proprietary heat management software. This advanced system ensures consistent, high-performance roasting while minimizing energy consumption greatly.
Equipped with an exceptionally efficient and powerful burner, the Stingray maintains reliable, long-term performance. Precision-engineered for maximum efficiency, it delivers remarkably low energy usage per cycle—without compromising on power or roasting quality.
User Protection
Setting New industry Standards in user safety
As an industry leader in coffee roasting machines, we set the highest standards for user safety. Our roasters are engineered with stringent safety measures, each product comes equipped as standard with multiple built-in safety mechanisms—at no additional cost.
Most importantly, our sub-atmospheric roasting chamber prevents gases and pollutants from escaping into the user’s environment, protecting roastmasters from excessive exposure to harmful emissions. At Coffee-Tech Engineering, we take every measure to ensure a safe roasting environment for you and your staff.
