The RX300 is a visual and mechanical masterpiece. The design is not just for looks; the extended side panels protect the critical probes, while integrated lighting gives you perfect overview of the trier and sight glass.
Labyrinth Insulation
Small roasters often struggle with stability. With our patented Labyrinth insulation, 30% of the heat is recovered. This makes the roaster immune to room temperature and ensures consistent roasting batch after batch.
Brushless Precision
No gear noise, only the sound of First Crack. The three advanced brushless motors provide silent operation and the ability to precisely adjust drum speed from 50% to 100% directly in the app.
Master Automation
Let the technology work for you. The machine automatically logs batch start/stop, and with the Auto-Roast function, you can replicate your preferred curve with a precision of ±1°C.
Cooling in 99 Seconds
Workflow is everything. Our high-speed cooling system stops the roasting process instantly and brings your beans to room temperature in under 99 seconds, so they are ready to rest immediately.
Santoker RX300 – When only the absolute top level is good enough
"Can you design a roaster that represents the pinnacle of what is possible on a small scale?" Chief designer Zhou Nan asked himself, and the result is the RX300. Winner of the iF Design Award 2026, it is not just a coffee roaster; it is a mechanical masterpiece created for sample roasting and the uncompromising enthusiast.
Mechanical Aesthetics: Form follows function
The RX300 is built with a "mechanical aesthetic," where clean lines protect the machine's vital components. The distinctive side panels are extended to protect the sensitive BT and ET probes, while an integrated light source at a 45-degree angle perfectly illuminates the trier and sight glass. Everything is placed directly in your line of sight so you can monitor beans, flames, and data without shifting your gaze.
Labyrinth insulation and extreme efficiency
Small roasters are often difficult to keep stable, but the RX300 solves this with its patented Labyrinth Insulation. By preheating the fresh air between the shell and the insulation, 30% of the excess heat is recovered.
Gas marathon: The extreme efficiency means a standard 450g gas canister can last up to 10 hours of continuous roasting.
Unwavering consistency: The preheated air makes roasting immune to room temperature.
The power of three "Dyson" motors
Where other small roasters often make noise and overheat, the RX300 uses three advanced brushless motors (for drum and fans). This gives you:
Quiet precision: No gear noise, only the sound of First Crack.
Control: Adjust drum speed precisely from 50% to 100% directly in the app.
Lightning-fast cooling: A full batch cools down to room temperature in under 99 seconds.
Intelligent Master Control
With the built-in Master system and Santoker App 3.0, data becomes your best friend:
Auto-Logging: The machine automatically detects when you "drop" and "discharge" the beans, and starts/stops your log automatically.
Curve Replication: Replicate a saved curve with a precision of ±1°C via Auto-Roast.
Flexible setup: Three mounting points for your tablet or phone give you the freedom to arrange your roasting setup exactly as you want.

Master 3.0: AI precision and data-driven perfection
The Santoker App Master 3.0 is not just an interface; it is your intelligent assistant that removes guesswork from the roasting process. The system gives you total control through three core technologies:
AI Curve Prediction: Simulates the entire process and calculates the optimal Rate of Rise (RoR) with mathematical precision before the beans hit the drum.
AI Image Recognition: Optical analysis detects microscopic color nuances in real time, ensuring perfect caramelization and eliminating human error.
Intelligent Atmosphere Control: Digital sensors automatically compensate for humidity and barometric pressure, delivering consistent roasting results regardless of the weather.
Scalability & Integration: Log all parameters via cloud technology, seamlessly transfer profiles from 500g to 120kg machines, and maintain full compatibility with Artisan software and Excel export.
The Story of Santoker: Engineering Behind Every Flame
The name Santoker (三豆客 – San Dou Ke) represents the balance between the three founders (San), the potential of the beans (Dou), and you as a guest/partner (Ke).
In 2012, two aerospace engineers and a nuclear engineer left their careers to solve one challenge: How to bring the precision of aviation into the world of coffee? The result is machines built with an accuracy that has made them a staple at the World Coffee Roasting Competition.
