Nucleus Link or Kaffelogic Nano 7 | Which is the best sample roaster for you? - Sous-titres bilingues
Hey Ingo,
what's the difference between the nucleus link and the catholic nano that's the question I heard the most the last days and therefore I decided to answer it to you in this video.
When you're looking at the machines, This is the nucleus link.
This is the catholic nano.
It's pretty obvious there is a close partnership between the two companies.
The machine has initially been invented by catholicic and still both machines are being hand-manufactured in New Zealand by catholicic.
The collaboration between the two companies started about four years ago when the nucleus team Mainly St.
Cora was looking for a And why they get in touch and started to collaborate together.
And some fruits of this collaboration have now been adapted to both machines,
so example, a chuff collector, new elements, boards, or some adaptions in the software.
But they
there are also some differences which are then catholicic or nucleospecific and in
this video we are going to have a look at the similarities and the difference between both machines.
But let's start with the similarities and you see the whole construction so the hardware of the machine is the same,
also the way the machine functions.
So it has this fan here which produces the airflow, sucks the air from the blows it until the top.
It has the heating element which is really fine granular and very fast which is then bringing the air to the necessary temperature.
Then it has the rose chamber which is kind of a cup which has no mass.
The idea behind it is to that the whole influence of the heat transfer is coming from the air so that you can really
fine and granular work on heat profiles and you have no influences from metal or mass in the rose chamber as well.
Just this super fast heat transfer from the air flow.
And then you have this so-called naked bean probe which is measuring the bean temperature
but it's constructed in a way that it's really super fast.
and that's the same in both machines.
Also with both machines you have this chaff collector which is made of glass so that you can see the coffee roasting process.
You have here this little cup where you can take out the chaffs after roast.
With both machines, you have a possibility to connect them with the cable to a software.
The is of course free with both machines, it's called Caffeologic Studio or Nucleo Studio.
You will realize also the basis for the software is the same and then there are some functions
which are then specific for either of the machines.
Now let's have a at the differences between them.
machines.
And the first thing we are going to have a look at is the amount of beans you can roast.
With the coffee logic in our know, as it comes, you are going to roast between 90 and 100 grams of coffee.
You have the possibility to buy a so-called boost kit, which enables you to roast from 50 to 200 grams of beans.
In the nucleus link,
the boost kit is already included, so you have a range of coffee to roast, but here it's limited to 50 to 100 grams.
So the whole machine is optimized for these amounts from 50 grams of green coffee to 100 grams of green coffee.
This is also the typical amount of coffee you get as a sample in coffee production, coffee trading at the roastery.
So 50 to 100 grams of coffee is the usual amount you roast in a sample roaster.
With this boost kit function, you are going to tell the machine exactly what amount of beans you're going to put in the machine.
The machine is going to adapt the roasting profile.
So here it is.
amount between 50 and 100 grams, then calibrate the machine to the amount of beans and it's going to adapt the roasty profile accordingly.
with the cathalo cheek nano,
when you're roasting without the boost kit, it's just going through one roasting profile, no matter what amount of pins you're putting in.
So you'll have a little bit of taste differences, but you can also play around with the amount of pins.
But also if you're using then the boost kit,
which isn't necessary for this machine,
you also have this granularity, and then you can also define the exact amount of pins you have and calibrate the machine accordingly.
Talking about calibration, there is another factor we have to have a look at.
on the altitude where you're roasting coffee at, the roast is going to behave differently.
And that's why the nucleus link has implemented a very simple calibration process, so you have an app.
you put in your altitude,
then it gives you a value,
which you can easily enter in the machine,
and the machine is then going to calibrate the whole system according to the altitude where you are at.
And the reason why they did this calibration process is that the machine is made to be taken,
for example, to coffee or rich in trips.
So if you have,
for example,
a in Hamburg,
where you're at sea level,
but you're going now to Nicaragua or Honduras,
us to search for coffees, you can adapt your machine to the altitude and then do a perfect roast there.
And more so,
if you,
for example,
have a partner in one of those countries,
you have your roastery in Europe and you want to precisely talk about the taste differences in the coffee.
The idea of the machine is that you can then calibrate the two machines.
profile and then you get the same roast and the same taste no matter where you are
and then you can easily communicate between coffee producers, coffee traders, coffee roasteries and you have a calibrated system.
With the Kafka check nano, you could do this fan calibration as well, but it's not that intuitive.
So you have the possibility to go into settings to a fan calibration,
but in order to make it really precisely,
you would need some measurements device or you're going to have a look at the movement of the beam.
So you have the possibility, but it's just not so much emphasis in the machine.
The machine is calibrated in a be used at any altitude that is going to produce a nice roast at any altitude,
but the roast is going to be different if you're using,
if you're roasting for example at sea level or at 1500 meters above sea level.
So if you're roasting the same coffee at different altitudes, you will get a little bit different results.
which is usually not an issue if you're just using the machine,
for example in your roastery or at home and you just want to compare different origins, you'll still get great results.
The big difference in the machines are the profiles and the logic behind profiles.
So the Kafka logic nano is coming with 12 profiles and the idea behind the machine is that it's
really simple and intuitive for anybody to be used.
So you just choose the right profile for your bean according to the altitude where the coffee has grown and usually you'll get this
information from your green coffee cellar that can give you the altitude where the coffee has been grown.
So you're just entities the machine is doing everything.
With the nucleus link there are 41 different roasting profiles and they vary depending on
the density of the bean you're roasting and also the processing of the beans.
So optimized for densities and processing of the beans.
And in order to help you finding the right roasting profile,
you initially going to measure the density of the beam, you get all the accessory that's needed for that with the machine.
It's not a too difficult process,
but still it's something you have to do before roasting,
you machine the density of the beam, you enter this in the app, you also then enter the processing of the machine.
The machine is then telling you which roasting profile to you, the roasting profile and do the roast accordingly.
In addition to that, you have for each profile five different characteristics and that these characteristics are defined in so-called pecs.
So when you're a bit more into roasting,
and you can also have a at the video I did with Rob House about that,
The of the roasting is differing depending on the amount it has been in different stages like the MyR stage,
the before the first crack or then also the development stage from first crack to the end of the roast and they adapted those profiles differently so that
they get a little bit different result out of it.
So you have,
for example, one pack which is a really classic cupping profile, but you have also a which is then more going into this.
Scandinavian filter roast,
or balanced filter roast,
omni roast,
or more espresso roast,
again different characteristic of the roast to play with so that the end you have more than 200 roasting profiles you can choose from.
We post machines you can choose any roast level or roast color.
The logic behind it in the catholicic nano are so-called roast levels which then are leading to a different roast color,
so a lighter or a darker color of the roast.
The of the roast is actually the factor that in France tastes most,
so you can choose this in the could also work with these rose levels in the nucleus link,
but you have also the options then to work with rose development time percentage.
So can enter different rose development time percentage.
and then go to a little bit lighter and darker roast and other feature and
difference between the two machines is that when you're marking first crack in the nucleus link it's going to adapt the profiles.
So for each profile there is an assumption of a first crack but it's going to When you mark the first crack,
then the machine is comparing am I in this range or am I out of the range and if it's out of the range It's going to automatically adapt the rose profile so that you get
then the right rose development time percentage and adapted profile It also has the possibility then to get a feedback.
So in the app that is coming with the machine you can as I said choose the profile but you
can also after rows go back to the app and then say with which profile you have
been working when you've reached first crack and then the nucleus database is
going to analyze if this has been the perfect roasting profile for you or
if it now would recommend another one for this particular beam and if that's the
case it would recommend you another profile and you can try a roast with another profile and compare the two roasts.
When you're having a look at the software the machines are coming with you also realize that the basis of the
software is the same catholic studio and nucleus studio
have about the same basis but then they have also some different features that are specific for the two machines.
But the similarity with both softwares is that the core functions are the same.
So where you have your database of profiles, your profiles saved, you can also adapt the profiles and work on profiles, you have your locks.
So you have the rows that you did before saved so you can analyze your locks and then do also changes
to roasting profiles according to the lock you have saved.
The software is giving you any information on the machine.
you different modes in the software,
you can go to engineer mode,
then you get really any value you can imagine from the machine and then adapt this if you want to find your new machine.
If you're a standard user then usually you're going to simpler modes where you don't just
have the settings you need to simply and intuitively work with your machine.
In addition to this the nucleus studio software has also the possibility to life record your OSU.
can connect it to your computer and then you'll see on your computer live where in the rows you are
so it's following the curve and give you a live information.
We have also been more granularities to enter the values for color change,
first crack start,
first crack end,
second crack start,
second crack end and then as said if you're marking first crack the system is going to analyze the roasting profile and if needed it's going to make changes and
immediately adapt the roasting profile according to the information that you have given.
Ecophologic Studio Software is available for Windows, Mac and Linux, and the Nucleus Studio Software is available for Windows and Mac.
When you're looking at the scope of the library of the two machines, you'll see quite some differences.
So, the Cafelor Chicanano is coming here as a roaster, it's coming with this chuff collector,
it's coming with a cable to connect your machine to the computer,
and it's coming with a little cup to measure the beans and then fill it into your machine.
The machine is being delivered in a sustainable packaging, in a cardboard packaging, which is then also really protecting your machine perfectly during transport.
When you're looking at the nucleus link,
you see the machine,
of course you will get the machine,
you also get the chuff collector, the machine is being delivered in such a strong case, this case is easy to be carried with you.
The whole machine with the case weighs about 12 kilos.
It's shock absorbent.
It's also protecting your machine from rain.
If for example outside on a coffee field trip, it's coming with such a cup.
It's coming with such a coffee tray and the density tube.
The density tube and the coffee tray are needed to measure the density of your beam.
It's being delivered also with a USB cable to connect the machine to your computer.
and it's coming with a smartphone app which is giving you the possibilities
to measure the configuration value for your machine as well as the profile and then
also do this feedback loop once you're done the rows to check if the profile
was the perfect for you or if you want to take another profile the next rows.
So all in all looking at the machine when you're scope of delivery of the features.
You see the machines are pretty similar,
but the nucleus link has been designed with more specific target group in mind,
which coffee producers,
coffee traders,
coffee roasters,
people that want to analyze green coffee and then also communicate together this green coffee which have a calibrated system so that no matter where they are the same roast
and they can then really work on coffees, work on profiles and deep dive deep dive into their green coffee.
Ticafelan logic nano been developed with a broader range of people in mind.
Of course,
also producers,
traders and coffee roses,
they really like the machine,
especially if you're using it more on one location because they still have all these features of the machine of this very
precise automated nice rose where you can just put in your coffees, your samples and rose it automatically and then compare them.
directly on the cupping table.
When it comes to home rosestica philochic nano is more into it.
So, still, I'm sure home roses will use the nucleus link as well, but you need to
have a particular interest into green coffee,
you're going to measure the density of the beans,
processing of the beans,
while the catholic and anion on the other hand is super into it if you actually don't need to know anything about coffee or coffee roasting,
you can just take your machine,
get a sample of green coffee,
put in the right profile according to the altitude where you've been at and then
to a lot of the rows and you get a really nice result in any case.
I hope this video was helpful for you.
I hope it gave you more clarification than confusion.
If you want to know more about those two machines then have a look at the other videos in our channel or go to our website rostrebles.com where you find
detailed information about the machine where you of course also can buy both machines.
Don't forget to follow our channel because we're posting a lot of videos.
