Not sure, I understand the question, are you asking if I can transfer the roast profile to a drum roaster? If so then no, a drum roaster behaves quite differently than a fluid bed roaster, but it will help on how I’d like to develop a roast on my drum roaster.

So it does not make sense to buy a fluid bed roaster for improving drum roasts. I will start with a low dose in my 1kg drum roaster and try to transform the data to a full load roast. I thought, there is a formula to translate a fluid curve into a drum profile. Useless hopes. So it could be only good for sensoric comparison. Thank you.

It makes sense to buy a small roaster like this if you need/want to sample coffees as these are usually only sent in 50/100g bags. Also if you want to see how coffees taste with longer or shorter development profiles and of course if you only have modest requirements re output quantities and or limited space

Love it!

Hi Dylan, don’t roast on the Cormorant any more - have moved onto a 1.5kg Golden GR1+ The graph I posted had smoothing set too high. I have since changed my bean probes to RTD type as they are more accurate and less noisy. For a high grown African I would still chose a quick ish roast - but with a longer time to FC. I drop most of my coffee between 1.50mins to 2.20 mins past FC and I’d definitely be trying to avoid that flick at the end.

@@beanobsessedroasters9073 Thanks for swift reply. I saw that after, that you'd changed to a different roaster. Found your videos really helpful. Such a bloat of theory out there but these have been really practical and helpful. Interesting to close off the diffuser at FC - I will try this next roast. I'm trying to avoid soft crashes after FC.

You can’t make a connection directly at the moment. I have added some additional probes which I have running through the Mastech and then into the laptop - one could also use a phidgets. There are plans to introduce a Bluetooth module for the internal bare wire thermocouple which controls the PID, to provide live data in Kaffelogic Studio in the future. However I don’t think this will happen until after the rollout of the new chaff collector.

The Onboard’s primary function is to control the PID and has been designed to be highly responsive. The external probe is less responsive but gives an easier curve to read an provides a real time roasting curve. Kaffelogic will bring out a Bluetooth module at some point which should give a real-time curve.

@@beanobsessedroasters9073 by looking at the placement of the external probe, maybe it should read the ET, and the onboard reading BT. That's my guess, im having a modded popcorn popper that have similar setup using 2 probes, BT & ET.

Only just seen your query - I use on 18g VST basket, but it looks like at least 26mm height would be achievable. As you twist the coffee will keep being compressed, so even with deeper baskets most of the depth will have distribution, though at say, 30mm height the bottom few mm might only be compressed and not distributed by the propeller - hope that helps

It determines a roast is done by a set bean temperature, either preset in the profile or user adjusted in the profile software. The roast level setting adjusts this end temperature. You can manually set what end temps correspond with the roast levels.

Where about's are you Marcin?

Exactly what I want to know. Have you made a purchase?

The lower area needs to be cleaned probably every 20 roasts or so, depends on your roasting style. Never clean the drum. However for a deep clean further disassembly is required, all very straight forward though, unless you are completely ham fisted.

Like any “cooking” the darker you go the more smoke you get. I’m in the light to medium camp - so don’t really see much smoke - especially as they’re 100g batches. However I’d always advocate ventilation of some sort. I use mine under the cooker hood works fine.

How so?

@@beanobsessedroasters9073 cz in 1st batch you shown coffee beans are not roasted completly .

@@sidbokhani3427 - how would you know?

With the greatest respect Sid - this is a light filter roast of a natural process - Ugandan. I don’t expect the colour to be uniform with this bean. People who judge roasts by sight, have no clue. This roast had nearly 2 minutes post 1st crack development, with an end temp of 215c and an overall roast time of 9.30 minutes - plenty. Had I roasted this for Espresso/Mokka Pot - I would have developed it further.

@@beanobsessedroasters9073 from the View of Beans , 1st batch you shown.

With the placement of my probes loads of 500g are no problem

@@beanobsessedroasters9073 it’s the original placement?

@@itamarkas no I have drilled and tapped a hole in the bean door

@@beanobsessedroasters9073 Thanks, I have an option to purchase the 500g model. Do you think the 500g model would be better from the Cormorant? Or The Aillio? Are you happy with the Golden Coffee Roaster? Thanks!!

You can connect the roaster using a special lead and the existing thermocouples - but I have chosen to install my own more accurate RTD and K -types and use Phidgets.

@@beanobsessedroasters9073 Thanks. How does the control on the fan works? Does it have a electrical control on speed? Thanks

@@itamarkas It depends on which model you buy, I you watch my video closely you will see that is uses a damper system. You should probably contact your local distributor or speak to manufacturer - as they can be configured to work either way.

Will you post an update on the roaster? How it goes at different roast levels, new pros and cons etc? :-)

This measured a 23 on the Roast Vision

@@beanobsessedroasters9073 My last roast was an Yrgacheffe Rocko Mountain Natural - also a 23 :-)

the ocd is good but it only flattens the top layer. the lower layers are not evenly distributed. so the even distribution is quiet superficial.

@@e5211 it's been a year since posting and after all the fancy tools I'm back to a chopstick with a few acupuncture needles taped to the end and a 58.5mm piston tamp. I can consistently make great espresso this way.

@@hcr32slider yeah, same. Except with a toothpick hehe

@@e5211 about 2 weeks ago I went from sewing needles to acupuncture one's. Wish I did it earlier as there was a huge difference. They actually settle and fluff the puck much more efficiently. Worth the $5 off ebay.

@@hcr32slider might give that a go. Thanks for the tip

Charge temp - will vary according to charge weight, bean density/size, altitude it was grown at, moisture content, ambient temperature and also the desired length of roast.

Hi Will - perhaps best if you join the Cormorant Facebook group - it's a great community there. Thanks Philip

Yes but I no longer use it - use VINT HUB and TMP 1101_01

@@beanobsessedroasters9073 thank you. i currently have an air roaster and ready to upgrade. was considering a small step, like the behmor or the gene.....maybe the hottop. but the cormorant seems to check all the boxes and overcome shortcomings of the 'cheaper' ones (albeit 2x the price of the hottop). is there a blog site where i can post some newbie questions about this roaster? nothing beats real world experience.

@@michaelelder9821 Plenty of users over on Home Barista in the roaster forum or if you put yourself on the waiting list which doesn't cost anything, but is fairly long - you can join the Facebook page.

@@beanobsessedroasters9073 thanks. i just joined HB. i was trying to dance around the event horizon, but appears i'm on a slippery slope :)

Yes - for the price - though can’t guarantee calibration. Did pick up on a batch of Indonesian green I had that was roasting oddly - which turned out to have a moisture content of 13.5%!

@@beanobsessedroasters9073 I’m looking to purchase it just wanted to make sure it hand some accuracy on green coffee beans. Thanks for this info Philip🤝

jakke fair point and amended - though I’m not really posting these for hits. Seriously though have pretty much stopped posting videos - takes ages to do them right and there’s always someone who finds fault in them - usually those that don’t put up any content themselves..

@@beanobsessedroasters9073 I didn't mean to be negative in any way. I fell in love with this machine (ordered one already) and this vid didn't turn up in my search results before. I just stumbled upon it through youtube recommendations. The only reason I mentioned it is that interested people get to see a bit more content about this roaster. I do appreciate you posting this video and think it's a pity you won't be making more videos. This equipment doesn't get enough coverage on youtube IMO.

jakke - I wasn’t talking about you, it’s just a trend on TH-cam these days, I mean this video has a thumbs down ffs

@@beanobsessedroasters9073 I gave it a thumbs up though... I always wonder myself why people do that, they have the choice to view what is of interest to them. Don't like something, skip and stop wasting your time but some people have all the time to waste. Don't let those idiots spoil your fun, there are plenty other people who do appreciate what you do 😉
