Roasting PNG with an eye on energy use
I pre-heated the FZ94 more than before to see if I could save energy overall. I used a bit more energy actually. Maybe I can lower the fan during warmup, because the fan sucks hot air out of the machine into the exhaust. I do want some airflow though, to ensure an even distribution of the heat. Taking care its not just the bottom of the machine getting hot.
Switched the machine on at 18:02
After warmup, 0.9 kWh had been used.
Gradually, the heater power declines from 2800W to 2000W during roasting.
1t 18:35 I DROPped the beans at 1.389 kWh used
After roasting, the machine with just some airflow and drum rolling takes 180W
