ADVANCED DIAL-IN
This app feature is to be utilized after you run a new sample entry stage and perform a
roast based on the initial recommendation.
During this first log, It is best to take note of the time of Audible first crack (when it has
two or more consecutive “pops”).
Using the “new sample entry” function the profile suggested will have your sample
usually cracking between a range 5:50min and 6:30min
Please note some coffee samples or specific coffee species will not have an easy-
to-define first crack (these samples are best to leave the roaster running its auto-
programmed functions of the suggested profile in the first stage). As the advanced dial-in
mode needs a defined cracking point to further refine an exacting profile for your sample.
For suitable samples, once you have completed a roast and have the exact time
registered for crack, please go back into the profile selector and in the next screen select
Advanced dial in.
In the First line Enter the Minute on the left and the seconds on the right. Please enter
minutes as a single-digit number and seconds as a two-digit number (i.e. for 6:01min you
would enter “6” on the left in the minute box and “01” in the right second’s box).
Next please enter the Profile Number that the sample was roasted on in the start profile
box (i.e. if your new sample entry suggested 207, you would enter 207 into the start profile
box).
Once the 3 data boxes are populated, please select done.
The information will be run through the algorithm and a new solution for the suggested
profile with be shown on the next page.
Select this profile on your unit via the menu tab or send it to the roaster when the tether
connection is made by first selecting the new profile in the Link pro software profile inbox
and then clicking the send to roaster button in the bottom right corner.
Weigh out another 100g of the same green coffee from the first roast into your dosing
cup.
Place in the roaster and then put on the chaff collector and press play.
Your new suggestion should now have a more focused crack range between 5:55min
and 6:15min which will allow for the optimized development of Maillard, sugar browning
stages for a fully developed expression
SAMPLE PROFILE PARAMETERS
The link core profiles have a standardized roast time, temperature increase, and development
% for each core. to unlock an honest assessment of a coffee we strive to get as close to the
target with through the link profile selector app.
The standard range for a coffee sample is between 7-12% development 4-6c temperate
increase after 1st crack. The standard roast is between 6:30-7:00min. Recommended
development of 9-10% if manually terminating.
Allowing a core profile to run automatically you will generally sit within these parameters.
Expect coffee to have first “pops” between 5:50min and 6:10min.
And rolling the first crack to be around 6:00 – 6:20min.
For this unit call the point of crack at the rolling crack where there are 2 or more consecutive
pops and a continuation of the first crack from there. At this point click the FC button on
the logging software or by hitting the far-right menu button followed by the Play button to
activate the first crack development timer.
The rolling crack between in a window of 5:50-6:10. A user is recommended to manually
terminate a roast if the development counter is above 10.5% development and the auto
termination has not come into effect. This can be done by + and then – on the unit or simply
clicking end on the software.
If a rolling crack occurs after 6:30min you may want to consider Re-roasting the sample on
a higher-powered profile. Please consider that for every 5 seconds late, choose a profile 0.5
higher in the profile number.
• Eg a coffee rolling crack at 6min25 using 209.5 profile. Selecting profile 210.5 will speed
this up to approximately 6min15.
Alternatively, if a profile has an early rolling crack before 6:00min you may consider applying
the same principle in reverse. For every 5 seconds before 6:00min look to remove 0.5 in the
profile number.
• Eg a coffee rolling cracking 5:50 using a 209.5 profile I would suggest that 208.5 be used
for a correctly developed expression.
