Roasting coffee on a boat

I posted this basic roasting method a few years ago. It is as simple and space efficient as it gets. Coffee beans endure long voyages at sea from Africa to the US in burlaps, although higher end coffee are in GrainPro bags which is mostly polyethylene plastic. "Charcoal Roasting"

Buckeye BC-1 Deconstructed - Magnehelic Parts List Note

It is indeed a good find. Thanks Ed for this info! If ordering directly from Dwyer, go to the custom page. The dual scale gauge can be ordered in Pascal and flow rate in m/s and everything is in metric, for the same price. Part number 2000-00MV
