Would be really easy to knock up a simple Trier/Sampler too Id reckon, cant beat daylight as the best light source.... 8-)

Re: FZ-RR 700 Baby Roaster

This is a really interesting piece of equipment and an interesting thought process youve got going there, Mark. I cant wait to have a look at a Baby at Denniss on Saturday.

Over the past week or so (inspired by the above posts), Ive altered my Corretto roasting technique. Ive always slowed the roast at first crack by turning the temp on the heat gun down whilst maintaining air flow. As with Steve, my roasts have to de-gas at least about 9 (or even 14) days before they reach their peak.

Im now trying to get more of a conductive heat process going after first crack by maintaining the temperature, but lowering the airflow. It certainly results in more smoke and chaff being retained in the roast. Bit early to tell yet whether the drying out process has been reduced and the "de-gas" period shortened. Im expecting it may well be.

Anyway, looking forward to Saturday.

Would be interesting to see what results you get. I havent roasted with a Corretto so am not that familiar with it. You only really need stronger air flow after the yellow stage towards 1st crack as this is when they will start to smoke and lose chaff. Maybe try also limiting the airflow earlier on as an alternative and then if you can pulse the airflow at short intervals once you get towards 1st crack that way you can clear some of the smoke and chaff (too much smoke after 1st crack for an extended period of time will probably present in the cup and be unpleasant). Not sure of you can do in the Corretto. Also once you reach well into 1st crack the beans have plenty of thermal evergy and usually dont require the continued application of heat to them if you are just trying for a drop right at the beginning of the second crack. You will find the temp should still rise without heat applied before stabling off. More so generally in a small roaster with a small chamber. By limiting the air you will find you will sacrifice some eveness of the roast as the heat will mainly be applied to a smaller surface area on the bean (if through a drum wall). I have found that this generally does not effect the roast as long as the variation in eveness is not too extreme and there are no burnt parts to the beans. In the larger roasters you can still get a very even roast due to the unsulated heat created in the combustion chamber so by applying playing around and limiting the air speed you should still be able to get a commercially presentable roast. I know a lot of commercial roasters do this.

The smoke from the Baby Roaster evacuates through pressure out some vent holes so has the advantage of not making the roasts smokey even though you are not introducing any new air to the drum. It is too hard to replicate on a larger scale so unfortunately roasting this way is limited to small batch. Main reason for this is that the bigger the batch size you really need to introduce more and more convective heat otherwise you would not be able to apply enough heat to roast the bean evenly and efficiently. Thats why good insluation in the large industrial roasters is extremely important to maintaining the heat inside the drum housing meaning you can play around with the amounts of airflow from fans creating a better mix of these different heat appliactions. I think you will find most comemrcial roasters will have there won theories on airflow but for most of the ones I speak to they know its effect is more than just clearing smoke and chaff.

Maybe if someone has a Corretto on the Gold Coast and they want to drop in I would be interested to have a look at it and see what it does. Have seen pics but never seen it in action.

Hi Mark

I will come down and bring the turbo  and heat gun setup.  I have used the motor out of my BM for the turbo but buy using  it with the heat gun would give the same results I recon.. after lunch tomorrow OK!

Cheers Graham..

Mate Im heading to Sydney tonight...not back till Sunday.

Maybe drop in Tuesday...the beans are on me.

Re: FZ-RR 700 Baby Roaster

I have just received my Baby Roaster from Chris at Talk Coffee and I am busting to have a go at this little roaster(my first roaster) however I was wondering if there is a breaking in procedure. Also there is a very small amount of surface rust on the centre shaft which I imagine will go after the first roast but will those beans be ok to use or should I do a sacrificial roast to be sure...to be sure?

Hi Jaymad,

Id definitely recommend a couple of sacrificial roasts to season the drum... Its the done thing with any metal drum

Enjoy...

Re: FZ-RR 700 Baby Roaster

OK, thanks Chris.

Damn, do supermarkets sell green beans?

Re: FZ-RR 700 Baby Roaster

Jaymad,

Your cheapest beanbay bean will be a great seasoner - one of the finest quality....

Use a Brazilian Pulped Natural or something.

@ $8 per kilo, 2 X roasts of 200gm isnt going to kill you....

yep, cant argue with that. The thing is I told the Chief I wasnt buying anymore green beans for a while(a specific time frame was not given ), so I must only use what I have in the stash.

Costa Rica Tarrazu SHB was the sacrificial bean for the roaster.

Having a play with the roaster while destroying some beans was interesting. From a newbie the hardest thing so far was working out the easiest way to remove the drum, while operating, from the base/drive unit without moving the base/drive unit off centre to the burner. Only 2 roasts in Im sure that will be solved soon enough.

With the drum seasoned now Im looking forward to tasting some of the beans.

I have a feeling Im going to like this baby roaster....a lot.

Looking forward to getting mine tomorrow

Re: FZ-RR 700 Baby Roaster

Id say roast the beans to season drum, keep the beans, try them, if you like it still drink it, if not throw them away. At least you now have a 50:50 chance of using the beans.

Re: FZ-RR 700 Baby Roaster

Thanks Dennis and Mark for a great afternoon seeing the baby in action.

Fantastic and logical explanation of the why and how and what to look for. Sampling and playing with so much variation and on a small scale. A perfect sample roaster which fits our needs brilliantly.

Made the trek from North West Sidernee very worthwhile.

Looking at my nice shiny baby roaster right now, trying to decide which bean gets it first ;D

Unfortunately though, back to Bunnings tomorrow morning as the Gasmate stove I bought on the way home has a non functioning igniter.... >

Thanks again guys, great afternoon.
