Your assumption may be correct. But it'll take awhile to dial in starting roasts for particular varietals. Plus it would help to measure bean density, at least by volume, and starting moisture content in order to pre-adjust your roast. You'll always be dialing in toward better results. This is one o...

Gary, I don't know if this latest experiment challenges your previous generalization because you're testing very distinct and different coffees from different places, one natural and one washed

Humidity sensor on exhaust - other gas sensors ?
In Rob's case, I don't think so. He is concerned with inlet temperature not being excessive and manages that with high airflow to distribute heat through the roasting chamber. In my fluid bed roaster, I don't do a maximum load so that the air will freely circulate through the bean mass. With my 1 Kg...

Yoshan DY-1 tipping
You might also set the air flow at maximum so that roasting temperature is spread through the roasting chamber. That's what I've done with a North TJ-067 1 Kg propane roaster. I start with the highest power setting when the beans are most able to absorb heat and bring it back throughout the roast. I...

Humidity sensor on exhaust - other gas sensors ?
Rob Hoos sets airflow at 100% from the outset on his 3Kg USRC roaster. At least that's how I understood that point in his paper on tipping. I do that now on my 1Kg propane drum roaster and get very good results, applying consistent heat without tipping. It helped to get used to a fluid bed sample ro...

Red/brown water when emptying La Pavoni Europiccola boiler
It's hard to tell whether that's rust or brass showing through where the chrome was removed by intensive descaling. With the siphon tube, you could try seeing whether Evaporust removes that coating. If not, it's copper. But it looks rough rather than shiny. I think someone mentioned earlier in the t...

Red/brown water when emptying La Pavoni Europiccola boiler
Agreed. I've never had a siphon tube look roughly red like that. They're either black with oxidation or pink, smooth copper

Humidity sensor on exhaust - other gas sensors ?
I can take a photo and measurements for 3D modeling, but we should also compare my trier to Eddie's. A spare part of a North or Mill City roaster could be hard to obtain without a special order from the manufacturer. An alternative is to find a pipe that fits the insert. BTW it really helps to have ...

Red/brown water when emptying La Pavoni Europiccola boiler
Do you have a rusted siphon tube? Also, BTW, if you do lots of descaling, that doesn't necessarily clean coffee oils in tight and remote places

Me too, if you'd like. I'm across the river from you and have a TJ-067
