Autosave File Naming

Artisan v2.4 introduces a powerful new capability to create custom data driven file names.

Artisan has always had the ability to automatically save a profile to disk at the end of a roast, or on a keystroke during the roast.  This is handy to prevent losing a profile due to forgetfulness or other accidents.  The file name auto-generated for saving included the roast title or a text string and the date for identification but was otherwise not very descriptive. 

Roast Simulator

The Roast Simulator allows to replay a previously recorded roast session. It allows to play with events, alarms, and other settings without wasting coffee.

Profile Transposer

The temperatures recorded and logged in profiles during roasts depend on the exact probe placement among other things like airflow. This makes it hard to compare profiles recorded on different machines. Luckily there are some points in a roast that can be identified based on physical changes of the beans during a roast, like the yellow point (DRY) and the start of first-crack (FCs). The recorded temperatures at those points can be compared and used to construct a mapping from profiles recorded on one machine to those on another machine. The profile transposer is a tool that supports the construction and application of such mappings along the temperature axis, but also along the time axis to extend or compress a profile.

Roast Comparator

While Artisan always allowed to load a second profile into the background, sometimes you want to compare the shape of more than two profiles. For this we introduced the Ranking Reports already in 2016 which allows to produce a nice Web page containing, next to sortable tables with the key data points of the selected roasts, a chart of all selected profiles. The drawback of this approach is that the report is static in that it is not possible to apply ad-hoc changes to navigate the representation. The Comparator allows to compare profiles dynamically.

Displaying Development Time Ratio in Artisan

Recent roast profile analysis has focused on using Development Time Ratio (DTR), rather than time, as being the appropriate measure for making changes in power or air flow after first crack begins.  Artisan allows multiple excellent methods to display DTR, and many other useful metrics too. This post will discuss how DTR can be displayed in Artisan during and after roast logging.

Artisan v2.1

This is the Artisan version we will use to prove Scott Rao wrong (or right). We extended Artisan in various ways to facilitate the application of his roasting theory.  Thanks Scott, for pushing us!

Profile Analyzer

Roasters often want to analyze their roasts to measure consistency, look for aspects of the profile that can be improved, and to create metrics to score the roast against a set quality measures.  Artisan offers many ways to provide information on a roast.  These include the Statistics Summary, Plotter and Math tabs, AUC (area under the curve), and many others.

Artisan v2.1 adds a new set of features to provide additional insights.  These features continue Artisan's heritage of exploring new ways of interpreting roast data.
