Record discoloration and efflorescence
With Kaffelogic, you can record the "Color Change" and "First Crack" timings that occur during roasting directly from the unit.
These records are useful for adjusting profiles and analyzing roasting results.
Recording Color Change
When the beans start to change color during roasting, perform the following steps:
- Press the "≡" (three lines) button on the unit.
- Press the "－" button to display "Color Change".
- Press the "▶" button.
This will record the color change timing.
Recording First Crack
When the first crack begins, perform the following steps:
- Press the "≡" (three lines) button on the unit.
- Press the "▶" button.
This will record the first crack timing.
Utilizing the Records
By recording the timing of color change and first crack, you can adjust your roast profile while comparing it to the actual bean reaction.
Please use this feature when repeatedly roasting the same beans or when creating new profiles.
How to Check Recorded Timings
When you record Color Change and First Crack, you can check them on the Studio graph after roasting.
On the profile, the predicted timings for Color Change and First Crack are displayed. The timings actually recorded during roasting are also displayed on the graph, allowing you to compare the profile's predictions with the actual roasting results.
- Left yellow vertical line: Predicted timing of Color Change
- Right dark yellow vertical line: Predicted timing of First Crack
- Triangular marks on the graph: Actual recorded timings of Color Change and First Crack during roasting
By comparing predicted and actual values, it becomes easier to understand the differences between the profile and the bean's reaction.
Please use this information as a reference when you want to improve the reproducibility of the same beans or when creating new profiles.
