Topic: odd Caffe Rosto problem (2 msgs / 38 lines)
1) From: Bill Crew
Hi all,
I'm new to the list and to homeroasting, and have what I suspect is a 
newbie question.  I just purchased a Caffe Rosto, and the first batch of 
coffee I roasted in it went well.  However, the last 3 batches I've tried, 
after 3-5 minutes of roasting all the beans have been blown into the chaff 
collector.  Any thoughts on what causes this?
Thanks for any tips,
Bill

Too small a batch size.  If you have a scale try 150 grams.  If you don't have 
a scale use the provided measuring cup *full* of beans . . . in the roaster the 
green beans should come up to the edge of the dome, or at least fully cover the 
air vents.  As the roast starts the beans will barely move . . . as they dry 
(and become lighter) movement will pick up.  At "first crack" the beans will 
expand, and will cover the dome (even if you couldn't hear the "crack" you 
would recognize it by the bean expansion) . . . by then movement will be quite 
"vigorous", and a few beans, but not many, may make it into the chaff collector 
.. . .
