Topic: Hot spot in popcorn popper (3 msgs / 120 lines)
1) From: Todd Musselwhite
Hey folks,
I've been using my poppers for a while to roast.
I have one that I've modified (separate power to fan/heat controlled with
dimmer switch) I used exclusively now and have noticed there is a definite
hot spot.
I'm using a Wearever 1250Watt pumper.  One side of the chamber has turned
black, while the other is still metallic.
This isn't a problem except I roast with the popper tilted so depending on
how I tilt, the beans are either on the hot side down, or cooler side down.
My roast quality has been inconsistent.  Figured out why. :)
What is the opinion of the knowledgeable people here as to what side should
be down.
Up till now I've not used the thermometer since I started using a hurricane
lamp globe for the chimney but plan on drilling a hole for the candy
thermometer.
1) Should I have hot side down with thermometer tip angled down to the hot
side to prevent scorching?  
2) Hot side up where most of heat blows through the shallow side of the
beans as they agitate thermometer tip down on cooler side keeping roast from
stalling?  
3) Hot side up, thermometer tip on hot side?  (Not sure why I'd do it that
way but open to advice).
Thanks in advance.
Todd.

This isn't likely, but thought I'd pose it anyway.... Was wondering whether
the black metal is on the "uphill" side the way that you usually tilt the
popper. If so, it is not "burned" so much as not burnished by beans during
the roast.

Brian, 
It is on the uphill side of the way I normally tilt.
 
I roasted with the popper level and let the tip of the thermometer follow
the beans around the chamber and was surprised by the temperature
difference.
 
I'm tilting, I mean leaning, towards putting the hot side down with the
thermometer tip down on the hot spot to keep from scorchng the beans.
