This was a great demo. I assume this is JohnF's toy ?
Is this the solid or perforated mesh drum option ?
Was the fan speed control a DIY or OEM ? The idea of just having enough airflow to move the smoke along during the roast is a good idea (IMO), then bumping it up for cooling of course. Is the cooling rate adequate ?
That was a neat air cooler that John had. I wonder how that works?
The Huky T500 is Taiwanese, ~$1300USD (+ extras), is reputed to do 500g (grams) or 1.1.lbs. Uses a heat source -- the IR propane cooker seems to be the common choice, but has some complaints wrt lack of tight flame/temp control.
The fan/blower unit is from the OEM. Not sure abt the speed control.
I was disappointed to see the beans not falling into the drum at startup. Having to do the lift/shake thing. That's a design flaw. I've also read that the blower/cooler can blow some beans out of the unit !
