Hi there to all experts in coffee land.
I have been using the BM and an el-cheepo heat gun for a month or so now but was given a new fandangle heat gun for xmas. While this is great my problem is that i can set the gun to any temperature that i want up to 630 degrees and two fan settings.
It has by default 3 fan settings
I can then use the LCD display at the back of the gun to change the heat to what ever temperature i like.
My question is what temperature would i set the heat gun to for roasting purposes, i notice in the fantastice post by Corretto that there are temperature changes at different stages of the roast, is this a function of the roast process ie., as the beans change or is it a change of temperature due to changing settings on the heat gun?
Any suggestions?
Thanks

It has by default 3 fan settings
- setting I only goes to 50 degrees
- setting II goes to 630 degrees
- setting III also goes to 630 degress but with a higher fan speed
I can then use the LCD display at the back of the gun to change the heat to what ever temperature i like.

, Low is 350 C and low air speed and High is nominally 650 C with a high air speed). Because the larger batches soak up the extra heat input, the roasts actually profile to around the same times with my setup except that when the 1st Crack is well under way, I reduce the HG back to Low and allow the beans to coast up to 2nd Crack.... If I left the HG on High for the entire roast, 2nd Crack will start much earlier, as in about 2 minutes after the end of 1st Crack, which is not really ideal and doesnt allow for the same level of roast control.
