Topic: Chaff fire in Quest M3 (5 msgs / 98 lines)
1) From: sci
I had a little chaff fire in the Quest just now. I was roasting Sumatra
Aceh Dry Hulled, hoping to hit V-, climbing up to 2C, around 425F I got a
torrents of billowing smoke clouds coming out the back vent. Looking inside
the chaff collector I found a little fire going, so I just let it burn out
by turning down the fan a little. This is my first Quest fire. Nothing bad
happened, except some smoke in the kitchen. I roast so the smoke mostly
goes into my outdoor vented hood. I do clean out the chaff collector about
every other roast, but will probably start doing it every time. I'm usually
roasting 4-5 batches back-to-back.

I also roast 4-5 batches back-to-back and have been cleaning the 
chaff collector on my Quest after every roast using a small shop vac 
dedicated to that purpose. It literally takes about two seconds to 
vacuum the inside area and the mesh strainer. I do this mainly to 
keep the airflow consistent from batch to batch, but it may also help 
reduce the risk of a chaff fire.

wow, this is the ONLY roaster I have not set on fire. I am either being
more careful or simply lucky.
chaff will light up fast. I still have burn marks on my deck when I totally
burned up a Hot Top; it was on fire...
CLEAN OUT THE CHAFF COLLECTOR EVERY ROAST, let's not be lazy. you will end
up with not only less concern
about fire but a better roast because of all around air flow.
why would you not clean the chaff collector aster very roast?

I have performed CPR on the equipment sent to the ER by Ginny.  I advocate
the eschewing of chaff in favor of more frequent disposal.
Respectfully,
