Topic: my first chaff fire (6 msgs / 218 lines)
1) From: Benjamin VerHage
I had just an awful day yesterday and was in a bad mood but I decided to ro=
ast anyway since I was out of coffee. The last thing I wanted to do after a=
 bad day was start the next day with no coffee. Anywho, I loaded up the Beh=
mor with 8oz of Ethiopia Kembata and let her rip on P1. Usually on an Ethio=
pian I let it go through first crack and stop, but this one was recommended=
 to go a bit darker so I let it roast on. Well apparently I let it go a lit=
tle too far past 1st as it got in to 2nd and I started seeing smoke billowi=
ng out the front of the roaster. I looked inside and saw little glowing emb=
ers of chaff burning so I turned it off and it died out pretty quickly. Onc=
e it was out I started it back up on the cooling cycle to try and save the =
roast. It looked ok, a little dark but ok. Smelled it this morning and it s=
till smelled pretty smoky so I didnt try any yet. Oh well. I need to clea=
n it tonight and run a cleaning cycle (it was due anyway). Hopefully
 the machine is ok. There are a couple small scorch marks inside the roaste=
r near the door and that's about it. The chaff collector needs a good scrub=
bing too but that should clean up easily enough. Has anyone had this happen=
 to them and have any tips for cleanup or things to look for?
I've probably roasted DP Ethiopians more than any other bean and never had =
a problem, but like I said, I only go through 1st usually and then turn it =
off. Guess the warning was there for a reason.

Ben I did have one chaff fire a while back. Clean up was easy; just use
Simple Green, rinse with moist cloth or sponge (not too wet), dry and run
cleaning cycle. I haven't had any recurring problems or issues since.
I do find sometimes on the left side by the door I get scorch marks after a
roast but it cleans up easily with a little elbow grease.
The roast I had the chaff fire with I let rest a little longer than normal
and it was ok. Not the best but still better than $'bucks.

Been there done that more then once. You need to keep a hot mit near by so
next time you can pull out the chaff collector and let it continue. I've had
a major over roast (read fire) and after a lot of scrubbing, the mighty
Behmor carries on without issue. It sure looks well used at this point but
keeps roastin up good coffee. Simple Green works great on the coffee
roasting residue.
Cheers!

The machine should be fine.  Prudence is usually good in this case, 
you can let chaff fires burn if you can handle the smoke.  They are 
not a roaster damaging fire.  They are very low energy and just show well.
As John said, Simple Green does the job very well.

Cleaned the inside of the machine last night with simple green. It took the=
 small burn marks out of the front corners with ease. I cleaned the chaff c=
ollector with some barkeepers friend and that worked well too. I ran a clea=
ning cycle and noticed a strong smoky odor coming from the smoke supressor =
so I ran a couple more cycles and it seems to be a lot better now. Going to=
 roast tonight for the final tryout. Thanks for all the suggestions.

I've been using Bon Ami (all natural polishing powder) to clean up any burn
marks that Simple Green won't get.  I usually have a few beans drop through
the drum to the chaff collector and they'll get burned and leave a mark on
the collector.
