G’day Ron (and others),

While I eagerly await the delivery (second export to Oz?) of my drum, I’m checking out suitable BBQ grills…

One question I have: The grill I’m really interested in has the notch where the rotiserrie rod sits about 200m (8in) above the burners.

Given that the drum has a diameter of 8in, this will mean a clearance of 100mm (4in) between the bottom of the drum and the perforated plate above the burners.

Is this too much? IE, will this mean that the drum is too high above the burners?

Also, this is a 3 burner grill with a total output of ~45,000 btu’s (45 Mj) - is that sufficient for coffee roasting?

Thanks!

It is better to locate your drum as low as possible to the heat source.

1 to 2" if possible. The heat is hottest at the bottom of the grill. and this will allow the drum to operate more efficiently. It will also save you gas as the the higher the drum from the source the more gas it will take to heat the drum and the beans to roasting temp. You loose about 50 degrees for each inch away from the source. For example if you have your drum at 2" and the temp there is 450 then if you raise it 1" and leave the gas valve set the same the temp will be approx. 400
