Roasting Intelligence (RI) Preferences

The following article shows how to set your RI preferences. 

Opening the preferences window

  1. Log in to the Roasting Intelligence (RI)
  2. Click Account > Preferences.
  3. The Preferences window with pop open, and it consists of the following tabs:

General tab

Units

Revise your preferred weight, temperature, pressure, and roast value units.

You can save two roast values (Roast value 1 and Roast value 2), one for whole beans and one for ground beans, with your roasts.

User interface 

  • Language: Choose your language from the drop-down menu. When "System default" is set, the RI takes the language settings from the account settings. 
  • Reset productivity hints: When clicking this initial usage hints will be shown one more time. 

Roasting

  • Timer: 
    • Modulation timer
      • Drying phase: From start until color change.
      • Maillard phase: From color change until first crack.
      • Development phase: From first crack until end of roast.
    • Development timer: First crack triggers development time. 
    • None: Switches off the timer
  • Alarm: When checked, an alarm will go off, 60 seconds before first crack and end of roast (according to the reference curve set).
  • Confirm end of roast: When checked, the RI requires a second click to confirm end of roast. 
  • Smart predictions:
    • Bean curve prediction: When checked, the RI predicts the bean temperature and RoR two minutes into the future. 
    • First crack prediction: When checked, the RI will predict when the first crack will most likely happen.
    • Flick prediction: When checked, the RI prompts a modal on the roasting chart to alert you about the flick's possibility during the roast.
  • Rate of Rise (RoR) settings: There are three RoR settings that define the speed (responsiveness) and smoothing (Recommended, Sensitive, Noise smoothing).
  • Between Batch Protocol: When checked, after stopping a roast, the RI will track the time elapsed between roasted batches.

Automation

  • Gas replay
    • Enable replay feature: Check the box to enable the Replay assist feature. 
    • Reset profile gas setting: When checked, activated Control measurements (e.g. Gas/Airflow control) will change to the reference roast's initial setting after the selected delay.
  • Temperature-based auto-start and end of roast: The start and end of a roast is triggered by a significant temperature drop when filling, or unloading the drum with coffee beans.

    Chart tab

    Chart axes

    X-axis

    The picture above shows the default values set for the Chart when the temperature unit is set to Fº, and Time expression is set to 60s.

    • The X-axis shows the length of the Chart, in terms of roast duration in minutes.

    Avoid setting the X-axis too close to your roasts' duration; roasting beyond the X-axis range set may lead to issues.

    If the X-axis (Time) settings need to be adjusted from the default values to better suit your roasting-style, we recommend to add 2 minutes to your longest roast's duration.

    For example, if your longest roast has a duration of 15:00 minutes, we recommend that you set the X-axis's time range to 17:00.

    Y-axis

    • The Y-axis displays the temperature units on the left side.
    • The RoR units are displayed on the right side.

    Note: Please keep in mind that the Y-axis's ideal range may vary depending on your roast machine, and the temperature unit, RoR setting, and Time expression set.

    If the Y-axis settings needs to be adjusted from the default values to better suit your roasting-style, we recommend that you set the set the Temperature Min, and Max ranges, as described below:

    • Max temperature: We recommend to set the maximum temperature based on the the hottest temperature measurement monitored from your roasting chart. Identify the hottest temperature during your roasts (e.g. Stack temp - 1200ºF/649ºC), and add 30ºF/17ºC to find out the Max temperature value.

    • Min temperature: We recommend to set the minimum temperature based on the lowest Bean temperature. Identify the lowest Bean temperature (refer to the Turning point) during your roasts, and subtract 30ºF/17ºC to find out the Min temperature value.

    Events and comments

    • Mark events by: Choose whether you want to mark events by Bean Temperature or Time.
    • Auto-mark development events: When checked, Color change, 1st crack and 2nd crack will be marked automatically based on to the reference roast
    • Hide past reference curve comments: When enabled past comments (except development events) will disappear from graph as the roast is progressing.
    • Show Gas curve as comments (on the reference curve): When enabled, each gas change logged on your reference curve will be displayed as a comment to the main graph. If the amount of gas changes in your set reference has reached the threshold defined in your settings' input field (Show gas curve as comments when there are more...), the gas changes will not be displayed as comments.

    The Show Gas curve as comments feature is only for roast machines able to track Gas automatically via the RI.

    Your roast machine is able to track the Gas measurement automatically,  when the measurement is set up from the RI's Machine preferences.

    Customize comments

    • Show Gas curve as comments (on the reference curve): When enabled, each gas change logged on your reference curve will be displayed as a comment to the main graph. If the amount of gas changes in your set reference has reached the threshold defined in your settings' input field (Show gas curve as comments when there are more...), the gas changes will not be displayed as comments.

    The Show Gas curve as comments feature is only for roast machines able to track Gas automatically via the RI.

    Your roast machine is able to track the Gas measurement automatically,  when the measurement is set up from the RI's Machine preferences.

    Reference curve

    • Sidebar: By marking the checkbox for the comment type (Gas, Airflow, Color change, etc.), you are choosing to display the comments from the right-hand side of RI.
      • Comments to display: Set the maximum amount of comments that will be displayed on the sidebar.

    Note: Having too many comments enabled in the sidebar can lead to display issues depending on your screen size, and the amount of measurements you track on the sidebar from RI. If you have a small screen display, we recommend that you do not set more than 3 comments to display.

    • Chart lines: By marking the checkbox for the comment type (Gas, Airflow, Color change, etc.), you are choosing to display the comments as chart lines on the main graph.

    Current roast

    • Add comments: By marking the checkbox for the comment type, you are enabling a button to have the ability to mark the corresponding comment type during your roast via the comments window.
    • Pre-fill toggle buttons (): If you have Gas/Airflow comments set on your reference, the RI will pre-fill the Gas/Airflow value according to the next Gas/Airflow comment set from the reference.

    Machine tab

    Within the machine tab you can connect your roast machine with Cropster. 

    If your machine is not yet successfully set up, look for the corresponding setup manual in the Cropster helpdesk or get in touch with Cropster support

    From the RI's Machine tab, you can set:


    Graph settings (1)

    • Color: Choose your preferred color for each measurement.
    • Chart: When checked, there will be a curve shown in the chart for the respective measurement.
    • Value: When checked, the current temperature of the measurement shows up at the right hand side of the chart.  

    Offset (2)

    If the temperature of Cropster and your roast machine slightly differ, enter the difference as an offset. 

    Note: A deviation of a few degrees is common, especially when the signal is spliced. If the deviation in temperature is bigger than 5°F/3ºC or if there are any uncertainties, please feel free to get in touch with Cropster support

    Rate of Rise (RoR) (3)

    Enable the RoR for each measurement by toggling the corresponding button on (green).

    If you have not looked at our FAQ on Rate of Rise and have some questions about its purpose, we recommend you do! Here is the link
