Probe Arrays

There are a number of reasons why using an array of probes to measure temperatures inside a roasting machine, instead of using single probes, seems to be a good idea. The intrinsic redundancy of probe arrays allows a machine to handle probe failures silently and to report them early on to the operator, avoiding down time. Another advantage is using averages of all readings per sampling time. This increases the stability compared to single probes. Averaging of readings gathered in parallel avoids also the main disadvantage of common software based smoothing, the introduction of delays caused by averaging readings gathered sequentially. Are probe arrays worth it?

10 degrees above FCs

Michael just asked me to extend the alarm system of Artisan to allow him to add an alarm that would speak to him once his bean temperature increased by 10 degrees after first crack start.

Tracking Energy Consumption & CO2 Production in Coffee Roasting

Artisan v2.4.6 introduces a new capability to estimate the energy consumption and CO2 emission for every batch roasted with Artisan.  This first-of-the-kind calculator uses logged burner settings, roaster machine specific specification data and energy source information to provide a consistent and methodical view of the roast machine’s performance.
