Roasting Intelligence (RI4) - Getting Started

This manual shows how to successfully perform your first roasts with Cropster Roast.

At the bottom, you will find some important recommendations that help you assign roast profiles and enter the green coffee inventory. This is a basic requirement to get the most out of Cropster Roast, optimize your roast consistency, track production statistics and create efficient workflows!

Make sure the RI software is downloaded and configured and that your computer is connected directly to the roast machine (plug and play integrations) or connected via USB through a Cropster Connector (data bridge). If you need assistance installing the RI, check our knowledge base or contact support.cropster.com.

Roasting Intelligence (RI)

Roasting Intelligence (RI) training video

This video shows you the basics of your first roast with the RI. For more information have a look at the manual below. 

  • Windows: Look for “Cropster Roasting Intelligence” in your program files.
  • Mac: Look for “Cropster Roasting Intelligence” in your applications.

In both cases, you might already have a shortcut on the desktop. Double-click to start.

RI - Pre-roasting

When you start the RI for the first time you will find the following sections:

  1. Menu
  2. Production section: Team member (=today's roaster) and today's production history show up here.
  3. Roast section: Profile and green inventory to be roasted can be chosen here.
  4. Measurement section: Displays real-time temperature and roast machine measurements.

Troubleshooting - no measurements shown

  • Can't see any temperatures or other roast machine measurements on the bottom right?
    Go to the application menu and click Account > Preferences > Machine to review your machine settings.
    Find the value that is not shown and make sure the channel is enabled and that the value and chart are checked as Visible.
  • Can't find the measurement value you are looking for? None of the expected measurements are shown?

    Log in to the online platform and go to the machine settings, by clicking on Gear symbol > Machines. There you can select the measurements you want to see in the RI.

RI - Start roasting

When you use the RI for the first time you will find a test profile Profile #1 and a test lot Green 1 to use for your first roasts. We recommend creating your own roast profiles and setting up your own green coffee inventory as soon as possible after your test roasts. 

  1. Select the name of the roast technician in the production section. 
  2. Select a Profile (e.g. Profile #1)
  3. Select Green Inventory (e.g. Green 1)
  4. Enter the Total start weight
  5. By doing this the Start-button becomes active. Load the hopper with green coffee.
  6. Click on Start.
  7. Within 30 seconds of hitting the Start-button, charge your roaster with beans. The roast starts.  

Note: By default, Cropster's automatic start and end detection are enabled so you can start recording the roast first and then charge the coffee. Cropster will detect a drop in temperature and mark the real beginning of the roast. The same is true for the detection of the end of the roast. You can edit this functionality under Account > Preferences > General. 

RI - During the roast

RI4 - Roast screen

You can see following information on the roasting screen:

  • Available temperature curves and their values on the right-hand side of the chart
  • Rate of Rise for all temperature curves (when enabled)
  • Available machine inputs like gas, pressures, rotations (machine and connection dependent)
  • Modulation chart at the bottom of the graph
  • Roast duration in the bottom right corner
  • Modulation phase timer (triggered by adding the comments Color Change and First Crack)
  • Event buttons

Under Account > Preferences you can edit which of the above information you would like to see on the screen.

Marking events/making comments

  1. Click anywhere on the graph to open the comments field.
  2. The comments field pops up. Enter the information you want to log for your roast, either by making a custom comment or clicking the event buttons like Color Change or First Crack. Comments/events are shown as a red vertical line on the graph and are saved for further analysis. 
  3. You can customize the comments field by clicking on the Gear symbol next to the heading Comments in the sidebar. Some of the possible comments are: 
    • Color Change: Click Color Change to mark the start of the Maillard phase.
    • First Crack: Click First Crack and start the development timer and development time % tracking.
    • Gas: If your machine does not provide automatic gas tracking through Cropster, you can use this button to track gas changes manually. Just enter the number without the unit (e.g. 40 for 40%) in the comments box and hit Gas to mark the comment.
    • Air: Enter the number without the unit (e.g. 20) in the comments box and hit Air to mark the comment.
    • Comment: For other information simply type text in the comment box and hit Comment.

      If you are roasting with an existing profile, information like gas comments are pre-filled so you always know what is coming up.

Note: You can also add comments after the roast is done. Simply click on the small timer to edit the time you want the comment to appear at and then enter your comment.

RI - Stop and finish roasting

There are two ways to finish your roast: 

  • Open the flap: Cropster RI features an automatic start and end function. After opening the flap, cool air will trigger the end of the roast. 
  • Hit the Stop button and click Confirm (within 3 seconds). 
  • Upon stopping the roast, the Between batch timer will start count.
Note: Check out the Between batch timer.

Before saving your roast, you can adapt the profile you have been roasting, e.g. by adding the roast times, end weight, color readings, notes and more.

When you have entered all relevant information, click Save to synchronize the roast with your Cropster online account C-sar.

You cannot edit the roasting curve after saving the roast. 

RI4 - Post-roast screen

You have successfully tracked your first roast with Cropster Roasting Intelligence using test data. Well done!

Stop and finish a roast - Between batch timer

Consistent starting conditions are key for consistent roasts. To help you with consistency, after stopping a roast, you can track the time elapsed between roasted batches. This will will help you stay within the time boundaries of defined between batch protocols. 

The Between batch timer starts from the moment you Stop the roast, and will continue to count until the next roast is Started.

Aborting a roast will result in loss of the timer count. Upon abortion of the roast, the timer will disappear until another roast is stopped.
