High Performance

  • Double wall carbon steel drum design for optimal heat transfer. 3mm gap between layers ensures perfect heat transfer for homogeneous roasting whilst reducing the chance of the bean tipping.
  • Additional insulation in the combustion chamber to ensure more efficient operation and retention of heat.
  • Very quick cooling 2-3mins with high capacity 1.5kW cooling motor.
  • Simultaneous roasting and cooling for maximum production output.
  • High efficiency Cyclone featuring detachable chaff bucket with level site inspection window.
  • Sight glasses for viewing in Drum Roasting, Burner Flame and Hopper Level.
  • Coffee sampler for removing coffee beans and inspecting during the roasting process.
  • System is prewired for easy addition and installation of an afterburner or destoner aftermarket.

Coffee Sweet Advanced Automation and Controls.

  • Next generation Coffee Sweet PC control system designed specifically for the Phantom Series of roasters.
  • 8 x faster processing speed with 3 x independent processors for increased functionality, additional storage space and future upgrades.
  • Real time graphing of all 4 thermocouple temperatures, Gas, Fan, Drum Speed and Rate of Rise on all.
  • Independent control module on the roaster with its own memory as well as PC connection allows for backup in case of computer issue.
  • Independent ambient temperature monitoring and relative humidity sensor.
  • 150 synced profile memory with automation. Infinite non-synced profiles can be stored on a PC.
  • 0-100 finite control over burner and drum fan. Control in 1% increments allows for more precise control over the roasting process. Burner modulation is from 0-100 in less than a second.
  • RS232 or Bluetooth (to come) interface with Coffee Sweet PC Software. Full control and automation on PC.
