Installing a Data Logger on My Kaldi Coffee Roaster
« on: January 16, 2021, 01:06:01 AM »
Hello All,
I am an avid coffee roaster.  I buy green beans either locally or on-line and then roast them in a Kaldi roaster.
Successful roasting requires that one control the temperature and the roasting time.  In the past, I used a hand-held thermocouple, writing down time and temperature.  What I really wanted was to have all this information automatically recorded on a computer with a data logger.

After several false starts, I finally accomplished that goal.  I purchased a Heat Snob; https://heatsnob.com/Shop.html data logger and connected it to my PC laptop.  Now, when I roast, a time and temperature graph appears on my monitor using Roast Monitor, the included companion software for Heat Snob.  I click a button when I start the roast, when it reaches First Crack, Second Crack and when I dump the beans. 

I then save that roasting profile and use it as a template to follow the next time that I roast the same variety of coffee.
The new roast graph overlays the earlier roast so it is easy to duplicate time and temperature.

To learn more about my coffee roasting, see www.fullbean.com/coffee/coffee.html.  Details on my Kaldi roaster can be found at the following locations
