Temperature Monitoring with Poplite
Dann-Oh	#1 Posted on 05/11/2016 10:50 AM

I am roasting a batch of Lavanta's Papua New Guinea beans. I know I like lighter bright roasts that highlight the bean and terroir flavors. I'm not too sure I'm hitting the temp ranges to achieve this since I don't have a way to see what temp I'm actually roasting at, I believe I need to hit about 426 deg F for a light city to city roast I could be wrong. I have ordered and received a thermocouple to monitor the temps during roasting as well as a glass chimney to try to help minimize bean escape during the roasting. My question for this post is where is the optimum location for the thermocouple? I have both a rigid probe and a flexible probe. At this moment in time I am not looking to record temp data I'm just looking to monitor the temp data.

For my set-up with the funnel insert, this results in the beans continually circulating over the copper tube the thermocouple tip is mounted in with the intent of getting more of a bean mass temperature than inlet air temperature. *So many beans; so little time....*
