In this video I’m connecting a coffee roaster to a computer for automated roast profile logging. The roaster is a Diedrich SR-1 sample roaster, but the procedure is similar for any recently manufactured commercial roaster. In this video I’m using a NI USB 9211. The software I’m using also supports the NI USB TC01 which only supports a single thermocouple channel and only works with computers running Windows, but is also much cheaper than the 9211. The software displayed is a single probe configuration of Typica 1.3.8, a free program that I wrote to make my work easier. www.randomfield.com
We use our sample coffee roaster to try out a recently arrived batch of Dominican Gold. This video is a little old, and the roaster has since seen some modifications. We were shooting for Full City + on this roast, and as you can here at the end may have hit just past it.
Experimental prototype of bubblebed (fluidbed) coffee roaster. This is a non roasting experimental-only version to determine optimum perforated plate pattern.
John Burton was awarded a NZ Coffee Roasters Association Lifetime Achievement Award at a formal awards ceremony on Saturday 21 May held at the Northern Club in Auckland. Many of the roasting fraternity were present at the screening of this tribute movie, as well as family and friends. Thank you John for your contribution to specialty coffee in New Zealand.
Use an old Kirby vacuum motor for the air flow and two Master Appliance 14.5A heatgun elements. The structure is cement board. Control is a Fuji PXV3, but I’m only using that for a set temperature. More info on the build here: www.homeroasters.org -CHAD
