Coffeetool Manual R-models (from September 2015 onwards) with Gas Control, Airflow Control, and Drum Speed Control measurements - Roasting Intelligence (RI) Setup

This manual shows you how to setup Gas, Airflow, and Drum Speed Control on Coffeetool machines manufactured from September 2015 onwards to Cropster's Roasting Intelligence.

Please note: This machine integration is in the process of being transitioned from a Beta version of the Roasting Intelligence (RI) software, to the newer RI5, and currently, requires a set up on RI4. If you notice any inconsistencies in the following manual that prevent you from connecting your machine, please contact Customer Support and we will help you get set up.

  1. Open the Roasting Intelligence app.
  2. Go to Account > Preferences > Machine tab. 
  3. Scroll down to Gas control.

    If you cannot find the Gas control measurement within the RI settings, learn how to add the Gas control measurement online. 
  4. Select Coffeetool PLC for the Gas control measurement.

  6. The RI needs to be restarted.

Replay assist preferences

When using Cropster's Replay assist feature, by default the gas setting will be reset within 5 seconds after the end of a roast to the selected profile's initial gas setting, so the roaster is heating up to charge temperature. To revise the settings: 

  1. Go to Account > Preferences > General tab. 
    • Enable replay feature: When this box in unchecked, no Replay button next to the Start button appears. 
    • Reset profile gas setting: When checked, the gas setting will change to the profiles initial gas setting after X seconds.
    • Smart detection: When checked RI will detect the start of the roast once the beans drop the temperature and the end of the roast once the beans are released out of the drum causing the temperature to drop.

Note: Check out Using Replay assist to learn more about using the feature.
