Surgical Convection
At 15 kg batches, precision is everything. The R15 Master utilizes 70% precisely calibrated convection heat (up to 250°C hot air). The advanced air premixing optimizes heat transfer, resulting in a significantly cleaner flavor profile and maximum sweetness.
The Axle-free Drum
Traditional central axles create uneven, direct contact heat. By removing the axle and coating the double cast iron drum with a far-infrared ceramic coating, the R15 eliminates roasting defects such as unilateral or bilateral burning.
Full Master Automation
The R15 Master does the heavy lifting for you. With full PID control, integrated bean suction (Auto Bean Loading), and Smart Cloud Sync with over 160,000 global profiles, you can replicate your signature roasts with a single tap on the screen.
Industry in a Slim Format
Space optimization is crucial in a modern micro-roastery. The ultra-slim cabinet houses a 750 kg heavy cast iron powerhouse but occupies minimal floor space, while the powerful insulation keeps room temperature completely out of the roasting curve.
Santoker R15 Master – Industrial volume with surgical control
Are you facing scaling your coffee production without losing the soul, sweetness, and clarity your customers love? The Santoker R15 Master is the answer. This professional model in the R series has been thoroughly upgraded with a fully automatic roasting system, groundbreaking airflow technology, and an ultra-slim cabinet that minimizes floor space in your roastery.
With a combination of massive cast iron, an advanced insulation layer, and a unique axle-free drum, the R15 delivers smoothness and flavor depth that traditional drum roasters can only dream of at 15 kg batches.
Technological superiority: Premixed convection heat
At 15 kg batches, precise heat control is everything. The R15 Master uses a high-performance hybrid system based on 70% convection heat (hot air) and innovative heat optimization:
-
Thermal air premixing (Airflow Pre-mixing): Using integrated premixing technology, hot air circulation is optimized, significantly increasing the efficiency of heat transfer.
-
Axle-free drum (Axle-free drum): By removing the traditional central axle, direct conductive heat transfer is reduced. This effectively eliminates classic roasting defects such as unilateral scorching and bilateral burning.
-
250°C High-energy hot air: The powerful hot air reaches up to 250°C. This ensures unparalleled roasting efficiency, perfect bean ripeness, and an exceptionally clean flavor profile in the finished cup.
-
Anti-interference insulation: The newly designed insulation layer ensures stable operation and completely uniform temperature curves by making the machine immune to external temperature disturbances in the room.
Master version: Your automated partner in the roastery
With the Master version, full automation is your personal guarantee of total consistency:
-
Full PID control & Smart Curves: The machine supports fully customized temperature curves. You can easily copy and permanently save your most optimized profiles – ready for reuse with a single tap on the screen.
-
Smart Cloud Sync: Access over 160,000 shared profiles in the Santoker app. Learn from the best roasters in the world and customize profiles directly to your own setup.
-
Auto Bean Loading: Avoid heavy manual lifting. The Master series comes standard with automatic bean loading that effortlessly sucks up the beans and starts roasting automatically.
-
Hyper-speed cooling (2-5 minutes): The ultra-powerful cooling cycle completes the process in 2 to 5 minutes. It immediately stops development and locks in the volatile flavor and aroma components.
"The R15 Master does the heavy lifting for you, so you can focus on flavor nuances. The ultra-slim design houses a 750 kg powerhouse delivering hands-free production with surgical precision."
