I am considering upgrading my home roasting setup to a gas Kaldi Wide. Part of what is so appealing is that this roaster is so bare bones and will be easy to modify to try different things.
I am going to drop a thermocouple into the bean mass to get my bean temp. Beyond that I want to measure the environment temperature as well. Where should I measure that? Somewhere above the drum? As is, this roaster has no forced convection. I am considering adding a duct hose and impeller over the bean hopper with a damper depending on how things go after my first few roasts with no air flow. If I did that would it be more valuable to look at this exhaust temperature? I am under the assumption that the advantage to trying to get an environmental temperature is that it would be more responsive than the actual bean temperature to show you where the roast is going - if I am thinking about it wrong please let me know!
