Topic: Yellow Beans? (8 msgs / 175 lines)
1) From: Chris Hardenbrook
How will you distinquish the immature beans from the others prior to roasting?  That's the problem.  Fortunately, it's not too much of a problem to hand-cull the few obviously immature under-achievers after the roasting.

I spent most of the day today playing with my Behmor. I roasted five Lbs. of 
Costa Rican beans (Christmas gifts), and a few odds and ends. The common 
theme was the usual inclusion of a few beans per batch that just didn't turn 
color, but stayed a lighter color (usually light green or pea yellow). I 
have poked and prodded around the internet without finding out why these 
beans don't change color. I even went so far as to pick a bunch of them out 
of the roasted beans and tried to re-roast them. All I managed to do was 
make smoke. If anyone can briefly tell me what the deal is with the renegade 
beans I would appreciate it.
Another thing I noticed was that I get a nicer roast using the Behmor when I 
am roasting 1/2 Lb. than I do when roasting 1 lb. By nicer, I mean a more 
even roast, with all of the beans being the same shade. Has anybody else had 
this experience?
Thanks, Ken.

I believe you're referring to immature undeveloped beans, also known as
quakers or floaters. They're normally sorted out via floating to the water
surface during processing before drying in washed processed greens. They
just ain't growed up enough to roast! Poor little tikes, picked before their
prime:-(
It can normal for a maximum rated batch size to roast less even than smaller
batch size, larger mass of beans doesn't mix as well. Some roasters are
worse than others at their maximum rated capacity. Behmor's rather slow rpm
drum one culprit.

Thanks miKe,
Now I can take some action and cull most of the immature beans before 
roasting.  I see that I may be better off dropping to a smaller roast with 
the Behmor. If I get some time I think I will try a 2/3 Lb. roast and see 
how even the coloring is.
Ken.

It may also be that outlet just doesn't have the oomph to drive the roaster
at max capacity.  You can try to drop the batch size a couple ounces to see
if that helps even it out.

If roasting to desired degree of roast in reasonable time not an issue low
voltage would not be the issue. In fact, lower roast temp environment would
result in more even not less even roast for a given batch size/bean mix
movement/air flow.

They are likely unripe beans.

Sometimes they're obvious looking much lighter, usually yellow rather than
green. Sometimes don't know 'til after roasting, especially DP's.
