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.

Artisan v2.4.6


Artisan v2.4.6 adds structures to calculate energy consumption and CO₂ production per roast.

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.

Artisan v2.4.4

This version improves some established automation features to better support the control of preheat and between batches protocols.

Supporting Between Batch Protocols

Here is our response to Scott Rao's call out to makers of roasting software to offer structures supporting the tracing and managing of BBPs (Between Batch Protocols) and warmups.

Blend Replacements

It happens that you run out of certain green beans. Often those beans can just be replaced by another one. However, if those beans play a part in one of your blends you might want to replace them with comparable beans without changing the recipe otherwise. Especially, if you just received the new harvest of that very same bean. Here we assume that you are managing your green bean inventory with
