(3)-1 Roasting method - Important points before roasting
1) Fresh beans
- Educate yourself about moisture and quality of fresh beans
* Dryness in the beans may affect roasting results
2) Preheating
Excessive moisture inside or outside the machine may result in scale
accumulation or roasting failure. Begin roasting only after sufficient
preheating.
3) External environment
Weather: Condensation caused by cold or humid weather may influence
roasting results. Allow sufficient preheating time.
Ventilation: Roasting is a combustion process requiring adequate amounts
of oxygen. Please check ventilation conditions.
4) Exhaust
Cleaning: Failure to keep machine clean may result in poor cooling due to
vent pipe blockage and decreased air flow. Taste and aroma of the beans
may be adversely affected if waste (grounds) is not discharged properly.
Always inspect vent pipe and cooling unit before roasting.
5) Roasting level
-Set to appropriate roasting level (hand drip, espresso, etc.)
◎ Attention
① Press the Reset switch. After approximately 15 minutes, visually
confirm that high voltage electric flow is being emitted from the
high pressure electrode.
② Confirm that the end of the igniter is making proper contact with the
fuel mouth (proximity of about 3~5mm)
③ Confirm that the heat sensor behind the igniter is making proper
contact with the fuel mouth (proximity of about 5~7mm)
