Anyone out there with a bread machine motor with CO top? I have been working on one for about 3 months. I like the strength and speed of the motor. Roasts a finished weight 1# easily with 13min fc. And the roasts are SUPER even. Test roasted a whopping 3# green batch today stopped just at beginning of rolling 2nd at 23mins. The slowest degree/min rise was 6 degrees at the slow point of 1st crack. Not happy with the time but the roast came out surprisingly well with no baked taste. Am going to cut my pot down 1 1/2" to increase the heat . Goal is to do about 24-28oz roasted in about 13-14 mins http://coffee-roasting.blogspot.com/ ps have done some mods after these pics, stir motor on/off switch on front. chaff exit slot.
This is a multi-part message in MIME format. Very impressive Edward--well done. You're goal of 13-14 min. for 1-2 = lbs. sounds right. My RK runs right in that range for city+ roast. VegasBob
Thanks for posting the pics! Brian
Nice work Edward, I have been using a similar setup for well over a year now. Check this out:http://www.homeroasters.org/php/forum/viewthread.php?forum_id2&thread_id1In the process of making a larger one, but in the mean time my PGR has been working fine :) My goal is to do a Kilogram or better, and my PGR does almost this much, but the capacity is a bit low. I found that insulating the outside of the roasting chamber helps a lot. Best, PeterZ Edward Bourgeois wrote: <Snip>
Edward, I have sampled some of Peter's homeroast and it is excellent! Les On 10/21/06, Peter Zulkowski wrote: <Snip>
Does anyone remember where I can find directions how to mod a bread machine so it constantly stirrs? I can't seem to find that again. Thanks in advance. Any other BM/TO how to's would also be appreciated. Chad
I've used 5 different brands of bread makers, and each and every one of them stirs long enough on the dough cycle to roast 1.5 pounds of beans with a heat gun. No modding at all. My sunbeam starts with two minutes at a slower speed stir, then will do 20 minutes at a fast pace, pausing for 3 seconds every 30 seconds or so. When I was experimenting to see if I could roast a kilo at a time, I turned off the machine for about 5 seconds, which let it reset to the beginning, about 7 minutes in so I would have a total stir cycle of about 30 minutes. I didn't end up needing it, but I wasn't sure how long a kilo would take. vicki Chad wrote: <Snip>
Chad A friend did mine. All i know was he bypassed and removed all the circuit board and ran a switch right off the motor leads.
Vicki What sort of BM roaster are you using? Ed
My roaster is an an oldish (1999) model 5820 Sunbeam 2 pound bread making machine. I have roasted in several other machines with the same results though, and without modding. v Edward Bourgeois wrote: <Snip>
Vicki Would you tell me a little more about your BM roaster. I saw that you've referenced my site http://coffee-roasting.blogspot.com/ so you know what I'm using. A friend wants me to make him a roaster. Mine is designed to do larger roasts than he needs but he does like the BM concept over the sc/ufo/to types. I picked up an oster 5821 at a tag sale for 2 bucks and might consider using it. Do you use the heat element in the BM? What's your process for doing a roast. thanks, Ed
I use a heat gun with my bread machine, Ed. I have been reading with interest the posts from folks who mod the bread machine so they can use the machine's heating element, but I'm not all that interested. My main goal in using the bread machine (well, other than the batch size) is to get good control over the roast, and the heat gun gives me that. I like the hands on part of this kind of roasting. I have some info on the way I do it on my weblog. See, http://taming.motime.com/post/597194.I have written about this before, so you could find it in the list archives, but the changes since that first roast are mostly related to my discovery that I can do up to about a kilo in my bread machine, and that I can fine tune the interval between first and second crack pretty precisely by switching to the lower temp on my heat gun, when first crack gets going, and then coasting. My goal is to maintain the temp for a bit, before going back to the higher heat gun setting, and bringing the roast home. I am, btw, using a really cheap heat gun, $34 CAD, and a very basic bread machine. If either of them goes, it's no great loss, and the heat gun is very light--a factor for me as with MS, my ability to manipulate a heavy object is sometimes compromised. In fact, the reason I decided on a bread machine, rather than a dog bowl, was related to my disability. I have an IR2 for backup, when even this is too difficult. Depending on how much I am roasting, I get to first crack between 9 and 12 minutes in. I have never gone beyond 20 minutes total time for the roast, and my bread machine stirs just fine on the dough cycle for that length of time. I have used other people's bread machines, five or so different models, and have yet to find one that couldn't handle 1.5 of greens without modification. That being said, I am new to this, and other people are probably better sources of information about this mighty fine roasting method. vicki Edward Bourgeois wrote: <Snip>
