Been playing a bit more with this concept this weekend, logging the full range of heatgun settings and recording the inlet temperatures. These Bosch guns are amazing! Basically a 7.5 degree increase inlet temp for every 10 degrees on the gun - almost right through the range!
Anyway, I've been playing with my profile sheet to incorporate this information in a usable fashion. I've attached a copy of a blank profile sheet as well as a completed sample, based on the preferred profile I'm using at the moment.
The most useful thing in my books is seeing where in the roast the input temp is being increased & decreased, and by how much, to achieve the final curve. I'd be really interested to see what others are doing the achieve their favourite results on different beans? Maybe I'm just OCD - but this info has transformed my roast thinking :-)
Happy roasting everyone!
