Coffee Roasting 121126

I roasted coffee again today taking somewhat better advantage of the heater controller.  As before, I ran the following profile:

  • Drive heat to 300F and hold for 5 minutes to dry the beans
  • Raise heat to 400 for 2 minutes
  • Raise heat to 450 with heat at max to drive through 2nd crack
Here are the profiles


The second profile seemed to work generally well with the heat held at 8 for 5 minutes, then increased to 10 for the remainder of the roast.

I've also improved the chaff collector and remounted the controls so they are all on a single board.


Improved chaff collector and controls mounted on single board
I also tried a simple vertical collector.  This did not work well as the chaff fell back into the beans when the fan was turned off.
