Topic: Altering the ambient temperature (was: Is there a way to recalibrate an Alpenrost?) (55 lines)

Here's an update on the results from my Alp:
I roasted yesterday, outdoors  - air temp 55 degrees.
Changed the batch size to 7 oz.  Instead of 8 oz.    I am roasting by
weight, not volume.
I also placed the ALP under an old upside-down garbage can, which has a few
holes in the bottom.  Did this to create a "warm" environment for the
incoming air to the roaster.
Set the Alp on "12" and let it go.   The results were a perfect roast of
Guatemalan Hue Hue!  Dark, with a spot of oil showing up on some of the
beans after resting 14 hours.
I'm convinced that the results from last weeks roast were seriously impaired
by too cold of air temperature.
The reduced batch size helped as well.
For now, I'm going to use the 7 oz batch size as my standard.   I will roast
again today, as the temperature will be about the same. This time I will
monitor the ambient temperature inside the garbage can to see where it at
during the roast.   I'll document my results.
 On another note...   Swissmar is sending me a manual.
