WS-300 300 g Lab/Sample coffee roaster has experienced several times upgrades to the latest version since 2014. It combines all features and functions which a commercial specialty coffee roaster should have to deliver customers better user-experiences.
What we upgraded based on the previous model?
1. 2-in-1 mobile Phone Bluetooth connection and Computer USB work with Artisan software for data logger.
2. Cooling tray buttons, one for cooling down, one for cooling mixing.
3. Brand new direct-row burner, the insulation performance is improved to better.
4. One key for warming up the machine automatically.
5. Hot airflow premixing technology increase the heat transfer ratio of hot air.
6. Improved precision, stability, and antijamming capability of temperature controllers.
7. Add drum speed control
8. Hot air pressure gauge for option
Solid drum and Perforated drum
We creatively designed the machine structure compatible with two roasting types: half-hot air roasting, and full direct-fire roasting by quickly replacing the solid drum and perforated drum.
Solid drum for half-hot air roasting, and perforated drum for full direct-fire roasting.
Drum still adopts the latest far-infrared shaft-less design, the raw material is carbon alloyed steel and it is coated by far-infrared ceramic coating. which can keep each bean inside the drum gets uniform heats during roasting, also it keeps clean drum inside and lower the machine noise.
High-performance direct-fire row burner
WS-300 adopts an improved high-performance direct-fire row burner to fix the flaws of controllability and stability by the previous normal burner. Fire flame is powerful to provide the even heats to drum. Temperature rise can be reached 16℃/minute, the first crack can be finished within 8 minutes.
Shaft-less Drum
Shaft-less drum is the best design for small capacity roasters, without shaft’s interference, coffee beans motion circle inside the drum reach perfect condition, that greatly improvs roasting evenness and flavor!
Fast Cooling
WS-300 equipped with powerful cooling motor works with cooling mixing arms, it takes 2 minutes complete beans cooling down job , rapidly lock the flavor inside the beans.
Dual– Channel Temperature Curve Output
WS-300 has professional roasting profiles tracking function, track hot air temperature and coffee beans temperatures simultaneously.
USB computer works with Artisan software and Mobile Phone Bluetooth wireless technology connects to roaster by “gangs of roasters” and “Roastmaster” two Apps achieve data logging.
Professional Chaff Filtering System
Dropped chaff inside the drum is drove out immediately by smoke exhaust system while roasting, no smoke remains. high-efficiency chaff separation device, chaff filtering rate can be reached 95% or above.
Maintenance-Free
WS-300 latest version Inherited and upgraded the maintenance-free design of WS-500, During use, only need to cleaning chaffs, no need for any professional or complicated maintenance.
Hot air pressure monitoring technology
Santoker patented hot air pressure detection technology, after installed the hot air pressure gauge, WS-300 still can achieve real-time display of exhaust condition. Hot air temperature control becomes more easier, even there is any chance of the external environment, everything is under control.
Far Infrared Coating Layer Drum
Far infrared coating is the protection layer for coffee beans, even the drum is heated by a strong fire flame, the ceramic layer can insulate the harmful high temperature, reduce the burnt and bitter taste.
