  3. Drum, Burner and Air System
    1. Double-wall drum in stainless steel.
    2. Burner: Riello or Premix.
    3. Flame is adjustable, and both the air flow and the flame are modulated continuously through the roast.
    4. Gas pressure regulator built, so the flow reaching the burner stays even.
    5. Insulated body, which holds the heat where it is wanted and trims energy use.
    6. Chaff collector, with a cyclone of its own downstream that separates at high efficiency.
    7. Cooling chamber worked by air vacuum: a strong fan pulls air through the beans while a sweep turns the batch over.
  4. Control and Instrumentation
    1. PLC control with a touchscreen operator panel.
    2. Works with Cropster and with Artisan roast profiling software.
    3. The roast curve is logged and drawn on the touchscreen.
    4. Dual thermocouple, reading bean and exhaust temperature at minimum.
    5. Extra sensors on the inlet air and on the cooling exhaust air.
    6. Electrical and control gear is Siemens and Schneider.
  5. Safety Systems
    1. Novasit gas breaker valve, which cuts the gas by itself should the pressure wander off its set band.
    2. Emergency button that drops every system at one press.
    3. Audible alarm that sounds once the temperature climbs to the level set for it.
    4. CE certification.
