How to track airflow or gas while using the RI

We currently support gas and airflow for the following machines:


  • Loring
  • Giesen (after 2014)
  • Probat Probatone (after 2012)


  • Probat Probatone (after 2012)

      For other machines: 

      Depending on the roast machine and on the machine's PLC or PID, we might be able to show airflow or gas reading.

      If you are using a Cropster Connector (data bridge) to connect to your roast machine, your readouts are limited to a maximum of four temperature values. With the help of a gas technician you can add extra hardware to retrofit your machine to facilitate gas readings in Cropster.

      Please send us a message via if you are unsure which connection type your roast machine supports.

      How to manually track Gas and Airflow within Cropster? 

      In case Cropster does not support Gas or Airflow measurement of your roast machine, you can track the measurements manually.

      1. Start roasting with the Roasting Intelligence (RI)
      2. When you adjust Gas or Airflow, click anywhere on the chart with your mouse and a comment-window will appear.
      3. Enter the value (just the plain number) and hit "Gas" or "Airflow".
        Note: The fields will be pre-filled, according to the gas/airflow adjustments of the reference roast you've set.
      4. The gas or airflow comment will be marked with a red line on your chart. 
      5. After you've synced your roast, Cropster creates a chart from the entered values, which you will see within our online platform C-sar.
