Re: CoffeeAir - 1kg Indoor Electric Roaster Trial
It turns out that 1800W just isnt enough, even if the air is recirculated. I was able to take about .5Kg to about 170C in 15 minutes. Its just not enough.
So, I picked up a propane torch, and plan to honor RoasterRob by using his brilliant torch idea. But, trust me, I have no metal working abilities, so this will be nothing like Robs artwork! Ill put some sort of vent in so that the smoke/chaff is directed outdoors.
In the US, we use 120V AC, and I considered running a 220V outlet, but the cost was out of the budget for now. 220V would allow me to double the power from 1800W up close to 4000W. But, I would have to re-build everything. Ive already roasted enough money.
Thanks all! Ill still keep you posted.

. The Gas Torch idea really does work though and if you grab a couple of different sized burners to go with it, itll make it easier to arrive at an optimum setup. What I did with my rig, was to position the burner (a cyclonic one I think it was, rated at around 2.5KW) about 40-50mm behind a coarse brass mesh (platinum would be even better 
) so that the flame would heat this up and increase the efficiency of the heat transfer.... Worked like a charm but I guess any burner with a decent output would do the job.
