CCR-1kg Coffee Roaster

I think the simplest method is to get one of those portable industrial fan blowers (about $200) and run some flexible hose so that the outlet of the roast smoke flows about 2-3 feet away from the inlet of the blower. As it picks up the smoke it will also gather about 80+% free air and mix the smoke with the free air resulting in some excellent disbursement of the concentrated smoke. The solution allows for a mobile operation so you can move it around depending upon the direction of the prevailing wind.

I forgot to also add this type of solution can assist with roaster airflow as it aids the exhaust - I've seen it used on some roasters that have poor inherent airflow design.

Damn, regretting coming over here to have a look at this thread thanks to your poking me on CS's!! I thought I was done with upgraditis and had nowhere to go, but shoot that looks like a damn fine bit of equipment. Gas is not really an option for me so this would be perfect. I like the idea that with next financial years new depreciation rules I could write the whole thing off in one hit too!

Then that's true I suppose, because the engineer told me that factory manager picked up some scrap metal from those residues, which left behind after making aircraft carriers. So I think that's the reason for hardness. :thumb:

That's a very thick piece of front panel metal BF Looks close to 10mm KK

go arduino/tc4. you could even Bluetooth it if you wanted wireless data logging

if space is tight, the tc4c is good, but I would suggest an arduino mega as the preferred controller if you have physical space. some apps are pushing the memory limit of the arduino and, while tweaking programs to optimize them is an option, a few dollars for the more powerful controller is cost effective. My Mega was $5 more than the base model. oh - there is also the option for the arduino to handle the heater and blower control functions. But that is probably best left until later, given everything currently works.

Tim - I think your charge temp looks ok as you are reaching turning point exceptionally fast for a drum roaster (sub-2 mins). Generally speaking, charge temp has a relationship to the turning point, rather than overall roast duration (although it obviously affects that as well). Lifting it a little may introduce internal scorching of the bean due to the rapid fall/rise. As a guide, I generally use 200 but that's for my gear and it may not work on other types.

Timbo, decafs have a habit of ramping too fast, regardless of the drop temp. Yes, lowering the drop temp will help dampen the ramp, but you need to think of decaf as perhaps a 0.7 of your normal batch. e.g. use around 70 - 80% of the energy Once you work out the metrics or factors for your different origins, varietals and processing type across various batch sizes, the good 'ol 3/4 rule for decaf works a treat ! Many a decaf was ramped too fast - even by the pros :-[

Don't forget that higher airflow on most roasters = faster thermal rise time !

I have been doing 200-300gram light roasts with good results on my Torrefattore so you should not have any problems doing the smaller batches--happy roasting!!!

Considering buying one of these with tax return money. For personal use and possibly as a way to begin a very small business (as a side income). Do you think the 1kg electric is a viable option for this? I noticed the seller on ebay but was questioning the legitimacy until I saw this thread. I've being trying to get into the roasting industry for 2 years with very little luck, may as well do it for myself! 🙂 (And yes I'm aware of the romantic notion remember I said 2 years!) Regards.

Thankyou for the welcome and reply bean. I have being roasting with a behmor for a couple of years. I'm not looking at even supplying a cafe, just a simple mail order for friends, family, and perhaps an ebay market. As i'm purchasing 20kg of green frequently it makes sense to upgrade from such a small capacity roaster to something a little bigger. To me this isn't necessarily a toy, though I understand it is compared to a 120kg industrial setup or something like that. And I suppose i'm attracted by the price. $4000ono isnt too bad considering the jump to 3kg is going to be more like 6-10k minimum (at a guess).

Just thinking out loud here, so to speak. Even though it may not make commercial sense long term to use one of these for roasting and selling coffee, it could be a good way to learn at a low entry cost and then resell for a significant portion of the original purchase price when the time comes to move up to larger (or outsource roasting work once suitable roast profiles and blends have been developed). I have no experience of commercial roasting, so anyone with more experience please feel free to correct me where I am wrong

Hi Bean Flying I just joined to express interest in this roaster. I have been chatting to John via email, contemplating purchasing this roaster. I currently have the Gene Cafe but looking to upgrade to a slightly larger capacity roaster. How is the roaster holding up? Are you still happy with built quality, tweakability, consistency of roasts? This sounds like a really dumb question but I cannot figure out how all the beans fall out into the cooling tray when you open door, as the drum seems to be sitting horizontally. I must be missing something? Thank you.

The thing (one of anyway) i like about the look of this unit is the profile where Tim (BeanFlying) has shown a couple of roasts on the same chart that demonstrate a reasonably high level of consistency (reply #76). The unit certainly appears to be adequately tweak-able with regard to profile with nice simple & solid electrics. The 2kg discaf recently for sale has similar drum volume & claims to roast a larger mass with fewer kW (don't stab me please RM), to me this may indicate the CCR has adequate power to mass ratio for a range of roasts on the snappier side rather than the bakey-er side (which is a style preference i know, but one i happen to like the possibility of), ie. no huge claims re. capacity, which is also nice John was very helpful in answering my queries re. build & communicated with me and the factory to resolve any questions. I'll certainly post here when the unit arrives & i've had some opportunity to get it running.

Hi guys, thanks for the responses, really helpful. It is reassuring to know the level of consistency the roaster has and tweakability as well. I have looked at the very helpful photos as well and the 'innards' seems sturdy and of commercial quality - would you agree Tim? I know the finish outside is not as nice as the European machines but I could care less about that. As long as the essential components are built to last I will be happy.

Thanks Bean Flying and all the other contributors to this thread, for some very interesting and informative info about this roaster. In as much, it has re-installed the "upgradeitis" virus into my system. :coffee2: I have been looking at the 500gm unit John has on the bay and emailed him. The 1kg unit being ideal for doing larger roasts, but it pulled me up price-wise. Having five 650W heating elements, it seems the 500gm unit would be capable of easily doing 500gms or more, based on BF's "rough boundaries" test roasts with the (5) 700W elements in the CCR-1kg. The max 1lb capacity of my well-used and aged Behmor was always a struggle, so 350gms became my preferred roasting "zone". 8) Just needing some more twisting of the arm and I'm there. :rofl: Cheers

if i didnt need a 15amp plug i would've probably already have one 🙁

Kevohere

That's an excuse :question: Haven't got a 15 amp plug either, but that's fairly easily rectified with a sparkie in the family. 😉
