Title: 1st batch roasted with Sonofresco
Post by: Tex on January 22, 2009, 11:40:24 AM
Sorta of dark (~Vienna), roasted with profile #7. The next batch was done at #5 and it looked a lot better. Both batches had 624 grams of green beans.

Should you desire to have a little more control, you can get a digital thermometer (similar to this (http://cgi.ebay.com/Digital-Thermometer-w-2-K-Type-Thermocouples-Sensor-A4_W0QQitemZ270331134524QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item270331134524&_trksid=p3286.c0.m14&_trkparms=72%3A1205|66%3A2|65%3A12|39%3A1|240%3A1318|301%3A0|293%3A1|294%3A50)) and measure bean temperature.   While doing that you can stop the roast at a specific temperature by turning the burner switch off.   I use the preset times as a safety if I'm multitasking.

I've had pretty good and consistent results this way.

I roast generally using preset 2 which gives me a City+ to Full City, depending on the bean. Of course my ambient temp here in the Philippines is around 80 deg F. I find that beans with a higher moisture content tend to roast darker quicker than drier beans.
For now, I await with anticipation Larry's widgit. I would love to be able to use the SF like I do my Hottop.
Cheers!

Interesting, because if I set mine on #2 I'd barely get past 1st crack... 3 takes me to about city, 4 city +, just past 2nd crack, 6 viena to french,  8 3rd crack... that's why I want to redesign the controller... it works as well as it can with the presets, but I want more control.

Yeah, but your machine is sucking in 35?F air instead of 80?. It was a balmy 71? @ 8:30 AM when I did this. Profile #5 gave me a FC+, which is what I usually prefer for espresso.
:icon_sunny:
The roast was of my Mongrel Blend (everything I have that's less than a full batch gets dumped into a 5-gallon pail & thoroughly mixed. This blend gave me enough for three 620 gram batches. It had C. American, SE Asian, India, & African, Arabica, plus a *bit* of good Indian Robusta for the tang.

Surprisingly, more folks like my Mongrel Blends than like the SO's.

Winthrop Harbor, IL, to Pearland, TX? That would be too much culture shock, not to mention what the sudden warmth could do to your body! Stay home & toss another log on the fire.

Check out this video at ~8:30 in (http://video.google.com/videoplay?docid=-3560051465057454694&hl=en), it shows the roast I did Dec. 20th. It was done on the other side of the house because the wind was from the opposite direction than today's wind.

It's almost worth the occasional hurricane to live in such nice weather. I can roast outdoors pretty much anytime I get the urge.

That reveals something about the drinkers, the Blends, or the SO's.   ;D

It's like the old tale about the Texan rancher visiting the farmer in PA.  They touring the PA farmer's spread, and Tex says, "Why, my ranch is so big, it takes me a day and half to drive my truck around it."  PA says, "Yeah, I used to have a truck like that."   ;D

Now using the second batch, having tossed the first batch as undrinkable. This one is a Full City (http://home.earthlink.net/~cm_harmon/images/P1240831%20(Large).JPG), and is very drinkable. The photo makes the FC roast look darker than it really is.

Once you get the hang of it I think you'll fine the sono very repeatable... with that said it may take a roast or two to become one with your new roaster.   Enjoy the trip.

Right milo,

And I'm sure that once I put a temp probe in the bean mass I'll get more repeatable results. It was the same with the UFO/CO - color & sound are good indicators, but for absolute control, temp is the only way to judge roast.
