大家覺得點呢? 大家都可以試下,平過你買domestic coffee roaster~~我用左$108 AUS to build up this machine. 不過domestic coffee roaster我都有 (IMex cr100).

The max patch size for cr-100 is 130g (I reckon). But the breadmaker can roast up to 1kg depends on the size of the basket. I use my cr-100 as a sample roaster and the breadmaker heat gun to roast a larger patch (normally 300g). Also, the cr-100 doesn't have temp control. So u can't really control the roast (U can't ramp). But as u can see, for the breadmaker, i inserted a temp probe into the basket and have a driller holder which can adjust the height of the heat gun, there is more conrtol of the roasting temp. The breadmaker heatgun method is called the "corretto" in Australia. Use "corretto" as a keyword for research if anyone interested. U can also find video from u tube.

Having said that, u can't compare any domestic roaster and the breadmaker heatgun to the commerical roaster. As the commercial roaster has a better temp control. U will know when u compare the graph between the both

I am trying the popper to roast bean and it is pretty difficult to control as the roast is quite uneven and it goes into very deep roast often. I am looking for other setup or machine such as Hottop. I saw your Corretto, and it appears it is worth to try. do you have any further comment, as comparing with popper and Hottop. Thanks Tony.

Hi VG,

I recently built a new one. It works very very gd. I'm very impressed with the result. I can't say it's better than the hottop cos I haven't used a hottop be4. However, one thing which is better then hottop is, it can roast up to 1Kg with gd result.
I found it is very easy to control the temperature. I'd done 3 roasts so far with my new corretto, it all came out very even. From my prespective, it gives a much better result than popper cos of its temperature control. And it's very cheap to built. My current one costs me $108 AUS (included Digital thermometer). So, it's cheaper than hottop and other domestic roaster.
If u are interested, u can pm me and i can give u my msn. So we can talk about the details.

Cheers,

Tony.

Maybe I should post my new corretto setup and the result

breadmaker: Palsonic breadmaker係二手店道買($20)-checked
heatgun: Ryobi EHG 2002係BUNNING道買($38)-checked
Digital thermometer: QM-1324 ($39.95)-checked
tripod(腳架): 上網買($11)-checked
fan:自己有唔洗錢-checked

所有野加埋總共用左AUS$108.95(大家成5就等如HK$)〔嘩!平過d咩 ”hottop” domestic roaster ~仲可以炒多d豆~正! )

將所有野加埋一齊就ready to roast(如圖)〔個腳架可以adjust高低,咁就可以control roasting temperature〕


可以開始!今次炒既係Costa Rica Royal Tarrazu.第一次試依隻豆.唔知係點ga呢? (300g)(炒豆日期:20/11/2008)


開機~~


8分鐘後 (開始有香味啦~)


12分鐘後(好香啊! )


14分鍾後~1st crack~~(好響啊 !果然係hard bean啊!)


6分鐘after 1st crack, first snip of 2nd crack就開始(炒完)立刻cool down~~(因為太忙,影唔到相 )


炒完~very even roast~net weight 257g幾好~~有15.6% weight lost.放入one way valve bag, age7日再cup~~

Hello Tony,

Thanks for your sharing. I have also setup a Corretto and the pricelist(HK$):

1. Breadmaker - $250 (from 2nd hand shop but brand new, I guess a new one costs about $600)
2. Heatgun - $250 (with variable temperature up to 600 deg, 2 wind speed, from Apliu St)
3. tripod - $50 (from Apliu St)
4. Infrared thermometer - $220 (from Apliu St)
Total: HK$770

I used the popper before, and I definitely agree with you that the roasts are much more even and controllable. I made 3 roasts, ~250g, time 18-23min, weight loss 15.6%-18%. As a Corretto beginner, I can see a great improvement from the popper (surely still far away from Shing Master la).
I have no idea if it is compared with I-roast or CR-2 but the cost is more economical at least. One demerit of it is that the silver skin may be blown everywhere that it is more suitably done outdoor.

My home computer is down, so I wish I may post some photos when it is repaired.

So far, I have the problem to hear the bean crack since the process is quite noisy (from both breadmaker stirring and heatgun), I don't know if it is my machine problem or may I need to increase the roast size (say up to 350g or more) so as to make it loud. Any suggestion?

VG

嘩!Infrared thermometer - $220 好平啊!!都係香港好!買咩electronic野都咁平 Very Happy .我覺得corretto出黎既result好過我個I-mex.
你講得arm~炒豆時,真係幾噪.要習慣下咁噪.我覺得i -roast同i-mex仲噪.所以我慣左.
係澳洲,有人用corretto炒豆,炒到攞獎.仲要個比賽mainly係比commercial roastary參加.所以corretto係work既~~我下個目標係要control個temperature好d

I see ~ I need to train my ear~~

As a DIY home roasting method, the adjustable temperature profile is the big advantage of Corretto vai
1. variable heatgun blow temperature
2. heatgun blow speed
3. heatgun height /position
4. use pan cover to maintain /release the heat

It is really an interesting method, I love it~~ thanks for your introduction.

BTW how you would cool down the bean?

I'm glad u like this setting. I can't take all the credits as I'm not the one who invent it. But I'm happy to share the information from Australia to Hong Kong coffee fans. Thx to "Corretto" - the one who invent this roasting method.

如果你可以等下,我今個weekend會整個trier.咁你就唔洗練聽聲練得咁苦辛啦~~~ Very Happy

cool bean我會將d豆放係個筲箕再用fan係咁吹.

Mine has two temp settings. One is 60 degree and the other one is 600. I switch my heatgun to its highest power setting. I adjust the height to control the heat.

Happy roasting. Have fun

Tony.

I look forwards to your new test.

I used fan and screen to cool ~80g bean from popper before and it took about 4 min to room temp. Recently I try to use vacuum cleaner to cool ~200g from Corretto, and it takes 2 min only, pretty effective. Perhaps you may try try.
