Re: Building my own roaster
Hi Maheel,
The original idea I had was a flap at the back, but am also considering a flap like you get on the old RSL lucky barrel.

Re: Building my own roaster
Hey Seb welcome to CS
Love the idea, i have been tinkering a bit and was thinking of trying something like your design.
Have you worked out a way to dump the beans out quickly for cooling? Or are you just leaving the "high" end open and then just tipping them out? A hinged flap or trap door might work if you have not sorted it?
I was thinking for mine along the idea of running the barrel on rollers or cogs on an angle like yours, gas heater under on angle. then you can just lift the barrel off as its not "attached" enclose the roaster in some sort of enclosure.
keep us posted

Re: Building my own roaster
Hi Andy,
Thanks for your comments. Really impressed with the speed at which feedback is given on this site! The chaff is definitely something I need to sort out. The idea I had was to make small holes at the back of the drum (about 3 cm long and about mm wide) which will allow for the chaff to fall out, but not the beans themselves. From what I have seen in my current test device, the slight angle seems to make the chaff collect there, while the agitators keep the beans moving forward. Ill have a look how this goes, however, your suggestion may come in handy. Was thinking of having a small 12 volt fan (that can cope with the heat), which i could mount at the front of the device.
Anyway, still a lot of thought needs to go into this one.
cheers
Seb

Re: Building my own roaster
..ok... 404 errors are gone now but attaching images here means they stay in the thread and can be commented on easier.
Great looking project and your first shots, while a tad dark, look like a pretty good espresso.
I would suggest looking at an "upgrade" to move the chaff out in the middle of the roast. It might be a blast of air or similar (few seconds of a heatgun?) as roasting the beans without chaff removal might make your roasts overly smokey.
Look forward to seeing the project develop.

Re: Building my own roaster
To answer your question kk , It roasts about 300 grams of coffee. Currently this one simply sits on top of the stove. I have just got a bigger drum (believe it or not, but it was lying on the side of the road on the Pacific Highway) its a perfect size for about 1.5kg, so my roaster is becoming a reality now. Im not the typical handyman but am getting there. I will post more photos when Ive started the bigger version, but have to build my daughter a desk first.

Re: Building my own roaster
Yeah, I know the corretto. Have gone from pop corn popper to that (oh and the frying pan option), but the heatgun and other hot air roasters seem to not give as good a result as using a rotational drum heated by gas. I cant really specify what it is, but there is a definite difference. It must be the hot air blowing across the beans while roasting. Maybe Im a tad to picky?
Cheers

Re: Buildihttp://coffeesnobs.com.au/Templates/Forum/default/email2.gifng my own roaster
Hi and welcome Sebba
Good to see another passionate home roaster
Looks like a design of a Cyprian BBQ can roaster


What volume can you roast with this design looks like 250gr at a guess
If you want 500gr + batches you should consider some of the home built designs that have been developed right here on Coffee Snobs
And they work well
Eg Corretto ok KKTO

Building my own roaster
Having experience with commercial roasters, (my wifes adopted parents have a coffee farm in the Byron hinterlands and do their own roasting in an old greek-built 15 kilo roaster. Theyve let me play with it!) I decided I am not happy to go the hot air roasting path. Im working on a small roaster thatll roast my coffee like a good commercial roaster, but in smaller quantities. I have already built a tiny concept version, which has, after an initial roast which was too dark, produced some very good roasts of great consistency with some very well developed flavours .
Have a look at my postings on my blog. Im interested in feedback, hints and tips!
