Looks good. With the back of the machine - is that with a cover removed, or is that just how it is with the 240V exposed to prying fingers???? If that were mine, I'd be rigging up some kind of cover for the rear. Ignore me. Just read that was with rear cover removed :doh:

Nifty but very robust looking 1kg roaster Would be following this thread as testing begins :thumb: KK

Oh, btw, I call dibs on it when you fall out of love.

Nice looking unit Tim, looking forward to reading about your roasting experiences on your new baby :thumb: :thumb:

Expensive to buy as an unknown and untested item, but looks like you got something at least as good as you would have expected. All Fotek gear - same as the SSRs I use with my PIDs.

Looking like the business! Great stuff mate...keep it coming!

First roast looks the goods. Does CCR have an air pulser/flow setup inside the drum? Impressive unit so far :thumb: :thumb:

I think I bought the first one of these, getting it a few months ago. John, 'coffee roaster' and ebay merchant, emailed copies of the manuals to me. Not sure how to upload the file with this message editor though.

One can also upload a PDF file in the same way as a photo KK

i see on ebay they have an Electric one, for 1kg, still in favor of electric, simple to use and no potential risk than GAS one. have a good try mate and let us know your findings. :angel:

what a genius work ! a real guru on coffee roaster. :thumb: 20 minutes roasting. Result was still a 20 minute roast but I am a little happier with the result. 80% power used for the first 6 minutes then reducing slowly to 60% before FC then 50% just after FC to the end. It responds well to airflow control but I have kept that simple at 1/4 until FC then 1/2 until the end. is this could-be the reason ? because the coach told me, for the first 2 mins of roasting, tune the power to about 50%, for moisture evaporated, then can be all the full power to roast, that is 100%. and the airflow control, they told firstly keep it shut, open to 3~4 when FC, then shut again, open til 3~4 again at SC. i think, if following coach's method, time will be less 20 mins. is it ?

:laugh: yes, lots of way to roast it, so that's the goodness of the manual roasters brings, everything can be customized. roast it to suits your requirements. some even prefer over-roasted coffees, they call it Charcoaled coffee, or something. 😃 read an article the other day, asking coffee belongs to acidic drink or alcaline ? a not well-known fact is, or a secret is, keeping your body in a alcaline state, then you won't have cancers ever. so there's some saying is, one cuppa a day, cancer-proof in a way. even me starting drink coffee. 😃 the pic is what i made myself, from roasting, grinding, to making a cuppa. you know, i'm totally a newbie on coffee. :stir

Hi John, lots of ways to roast a bean 😉 I like a little airflow as one thing I dislike a lot is anything smokey or grassy taints in my roasts so I have always used a little fan even early in the roast. Increasing it around FC and again toward SC if I am roasting into it decreases the smoke in the drum and moisture and lots of other things. Some may take issue with this method but it has worked for me. I will have a play with 100% power after I get a few more roasts done and don't mind destroying some beans. To much heat and I am a little concerned of charring the outside of the beans due to the configuration of the elements and perforated drum but some experiments are needed and my concerns may be unfounded. My plan is to fit a datalogger into the roaster in the next week then have a serious experiment with just one specific bean and stay with 1kg and then play with the variables and see what I like more 🙂

1.8kg roast in my Torrefattore--drop temp 160 on full heat, turn on air pulser at 5min. mark and pulse for 6 seconds every two minutes, back off heat approaching first crack around 200C mark when I switch off auto air pulser and go manual, PID cuts out around here and heat momentum in the beans is sufficient to keep roast developing without stalling until I reach the roast level I am seeking, during this period from 1C to approaching 2c I manually pulse air through the drum to purge chaff and smoke and slow down temperature to required level. Dump and cool as quickly as possible, with a 1.8kg roast I transfer 50% to my old extractor fan cooler as built-in external cooler does not cool fast enough for my liking. My datalogger which sits in bean mass near viewing glass usually runs 12-15deg higher than the drum air temperature probe. First crack 12.30-13.30 mins. end of roast around 3.30min-4.30 depending on roast level.

The pin on the end of the drum - does that go into a bushing, or bearing? A Bean temp probe will be an interesting challenge. Perhaps taper the end of the fins back a tad so beans still get turned, but a probe can go near to the top of the fin? Either that or a fine notch at the base of the fin and a fine probe, but need to avoid places beans can get caught so clearance would be tight. Where is current probe? Is that it just below the trier?
