I have found an extremally frustrating and at the same delightful change in my roasting profiles after installing a 6in cloudline to help in exhausting the smoke in house.
Delightful in the manner that the fan performed well in keeping the miss happy and it changed my profiles immensely.
Wait, Changing my profiles was not the objective. That’s the frustrating part and profoundly changed the way I roast.
Bullet => Direct Exhaust by a duct out the window.
Play with Power and fan to keep the profile.
Bullet => Elevated 8to6in reducer => 6in splitter (Sucking the air from cooling tray => Cloudline 6in => Window.
Play with Power and fan to keep the profile
Cloudline starts at 50%, at the start of yellowing (usually at 150’c) up it to 75%, 5’C prior to FC up it to 100%.
Sample Roast of previous setup:
Sample Roast of current setup:
Things I have found out:
- Requiring less preheat. It dropped from 20’c to 30’c on most of the coffees I roast.
- Less overall heating from the bullet. Usually I start at P7 and keep it running. I find myself dropping to P6 at yellowing and P5 prior to first crack.
- ROR after FC usually drops bad and crashes even at P7. At P5 now and just keeps rising.
Only thing I can concur is that somehow the inline is basically working to remove excessive humidity from building inside the drum.
Anybody faced the same?
