    Where you point the heatgun can help or hinder the flow of the beans.

      Yeah I wondered about that too. I point it at the opposite side.

        Could be the go G62....

        You might be able modify the stirring paddle to some extent so as to displace a greater volume of beans with each rotation... Maybe weld a short piece of stainless to increase the height of the paddle near its periphery so as to replicate a reversed L. Might be worth trying... :-?

        Oops, sorry Mal. I somehow missed your post. :-[

        I dunno about welding a piece on, but I could bolt something on. The paddle is made outa teflon coated aluminium (I think). I live round the corner from my Bros dairy farm and have unlimited access to mountains of stainless steel junk from the cow shed hes discarded over the years.

          Hi Gronk,

          I have the same setup as you, the BB280, Ryobi variable gun etc, but use a thermocouple to output to a PC. It gives a result like this when converted to an excel file.



          I do 300g batches which reduce to 250g after roasting. Anything smaller doesnt seem to move the beans around consistently. I havent done more so cant help you there, but this amount works for me. I start the gun off with the lights showing 200C and leave it at that for about a minute and then nudge it up just a little - maybe 3 of the little notches, then do this again every 45 secs or so as the roast progresses, increasing every 30 secs or so towards FC, and the heat gun is showing as being on the hottest setting, but there would be more to go on the dial.

          As FC happens, I turn back the heat to 500 and turn the pedestal fan to a higher setting, which slows the roast right down, then keep going to however far you want to take the roast.

          I really rely on the graph on the laptop, as it shows what is happening.

          Cheers
