Topic: US Roaster Corp Sample Roaster (22 msgs / 411 lines)
1) From: miKe mcKoffee
Anyone have direct experience with the US Roaster Corp's Sample Roaster? Or
know anyone that does? Now that the deal on the used San Franciscan has
seemingly fell through I made the mistake of calling them. Discovered $1600
less than equally outfitted SF1! Not as good looking as the SF1 and still
not cheap at $3600, but roasts profilable from 5min blast roasts to whatever
you want, variable pressure gauged gas cast iron burner, variable air flow,
gear driven drum, tryer, sight glass, greens hopper drop, Watlow temp
controller with "J" type bean temp probe, 65rpm solid wall vaned drum with
meshed ends for air flow and 1.2# max batch size. Data logging additional
option. Sweet sounding and looking mini- commerical drum roaster.

No direct experience here, but I just met a roaster that uses 
one.  They are happy enough they are going back for another larger 
one.  Wandering Goat roasters in Eugene.  You should be able to call 
and talk to them about it, or come down for a visit.
I will of course chime in that that is pricey for a 1.2# propane 
roaster.  Ever consider building your own?  Even with some of the 
fabrication that might need to be done, designing is a kick and you 
get exactly what you want that way and you can way undercut that 
$3600 (if money is of any concern)

I built my sample roaster for about $600 and that included contracting out some 
of the sheet metal work.   Dan

I built my ghetto version of Dan's for about $200, but
mine is ghetto wallboard, Dan's is COOL sheetmetal!

<Snip>
Both roast the same, GREAT!   Actually, even with insulation, I would not call 
my sheet metal cool.   ;)

7) From: Michael Biondo
Jason, Dan...
<Snip>
Do either of you have any pictures of your roasters posted anywhere?  As one of
those pesky newbies, I'd sure like to see what others are doing with this type of
homebuilt roaster.
Thanks...

Sure.  I removed my roaster page on the server at work, but you can see the 
"Homebuilt Roasters" section of www.homeroasters.org

Quoting Michael Biondo :
<Snip>
There are some web sites with pictures of home-built roasters, like this one:http://www.sweetmarias.com/homemade-homeroasters.htmlWhat I'd love to see is something showing the design of a sample roaster, maybe
some pictures of a half-assembled roaster. I don't think it's going to happen
soon, but one day I'd like to build my own sample roaster, and it would be nice
to have a working design to start with.

10) From: Dan Bollinger
<Snip>
Paul,  I plan on doing that sometime next year.  I took the sample roaster's 
function and designed it to be made in a home shop using a minimal amount of 
sheet metal and machining tools.  Even then, most people will have to contract 
out some of the work.  Jason's version is a home shop version.  Check out his 
website. I think there is enough information in the pictures to build one from.

11) From: Tom & Maria - Sweet Maria's Coffee
Sorry to hear about the sample roaster deal falling through Mike - I 
was about to email you directly to see if you had received it yet. 
Basically I am having trouble keeping up on email since I pack orders 
for at least half the day! It's crunch time. Anyway, I have looked at 
the roaster at it is cute, have heard that one broker friend I know 
liked it, but also heard that at the Roasters Guild everyone avoided 
their roasters. I would not touch anything bigger from them, since 
they are refitted Turkish roasters, but this sample roaster seems to 
be a custom build product. I have some other personal comments though 
about the company themselves, and will email you those offlist. Also, 
did you see that crazy lightly-used Italian-made elec. sample roaster 
on Ebay. It sure is good looking!!! - sounds reasonable that it was 
made for 1 kilo but the owner says it is better as a 1 lb roaster... 
they are in the bay area but I don't know the company.
Okay - back to the orders.... I did update my sample log, but not 
many other web changes lately. Off to Panama, El Salvador and 
Nicaragua on Jan 10 to cup and find some new crop lots...

To which I add: How about the Ambex?   Their small unit, the YM-2 is 
reasonably handsome and roasts up to 5 pounds at a time.  Anybody know the 
asking price, too?

The Ambex YM-2 lists for $5500. I went to visit Ambex in Clearwater,FL 2 
years ago and got a first hand look at them. They are nicely made and 
look like they would be easy to fix if they ever broke.

Did you perhaps miss that the second set of pictures down(Derek

half-assembled roaster" there.

15) From: mIke mcKoffee
Not too bummed about the SF1 fading away, not too happy either but it's an
oh well the guys a jerk! Yeah, I saw that Balestra but have very little
confidence in any roaster touting batches much over 1/2# running 110v. Just
not enough heat power to have much control of the roast. Was also watching
one that just went too high for me, a Diedrich IR7LP, went for $6900, a good
price for it but not a super steal.	
Alchemist, sure I've thought about building a drum roaster on and off over
the years. But it would have to have everything I want: off the top of my
head a tryer, bean and drum temperature probes, variable air flow, variable
heat, insulated drum, chaf collector, beans dumped to fanned cooling tray
(without having to man handle the drum and needing welding gloves), sight
glass a plus but not mandatory. I somehow don't think I'd ever get one built
I'd be happy with so looking to buy. But that's ok as far as I'm concerned.
I didn't build my espresso machine or gas range or M&K speakers or TEC high
temp grill or Traeger smoker grill etc etc etc either! 
Ambex wise I'm leary if for no other reason Tom doesn't believe they're that
great of quality build wise. Though I'm still considering the YM-2, have
talked to a number of satisfied users, though doubtful of the experience or
standards of Tom. And that $5500 price is going up about a Grand after
12/31. FWIW Ambex will be coming out with a smaller one pounder next year
similar to US Roaster Corp's while US Roaster Corp is coming out with a five
pounder similar to Ambex's 5# Y2 (Except US Roaster Corps 5 pounder will
have two separate fans, one for cooling and one for drum air flow so you can
roast while the just finished roasting batch is cooling). Think they're in
competition with each other!?-) 
For today anyway I'll continue along FrankenFormer Rosto 1/2 pound roasting!
Which would likely remain my normal personal use batch size whatever roaster
I may or may not move up to.
Now off to roast a batch of Honduras @35F ambient and still hit my profile,
just finished a batch of Yirgacheffe before this post:-)

Mike, that may be true for a fluid bed roaster, but not for a drum 
roaster.  I may not be able to do a fast 4 minute inceration roast at 
a pound, but I can easily do a pound at virtually any profile form 
7-20 minutes.  There is a lot of energy in 14 amps at 110v.  With my 
full power now, I have to really watch out that I don't have the 
roast run away from me.

Alchemist,
You are putting your power where it counts.  How much power does it take to
run all the bells and whistles of those sample roasters?

Probably no more than a couple of amps.

The only other bell and whistle is a fan I think - not too sure 
though.  I will be adding one soon anyway, so I will find out.

That was not including the heat supply. I had assumed it was gas, but I 
guess you meant the whole works with electric heat?

Alchemist, I stand corrected on the 110v electric heat being an issue for
one pound batches. Slipped my mind after you added the second heating
element in your wall insulated drum roaster you gained ample heat headroom,
good to know. Any idea what the largest batch size you can roast to a say
minimum 10min FC at say ambient 50F? It'll be interesting to see how much
adding airflow affects performance. Doesn't take much flow so likely not too
much. To answer someone else's question drum airflow isn't simply mixing the
internal air like convection, it's blown through for a cleaner roast taste.
And usually adjustable so if you want an old drum style smokier roast you
can.
The other bell and whistle drum motor of course. Very minimal draw from fan
motor and any electronic temp monitoring devices.

This is rather a Gestalt guess only, but I would say about 24 
oz.  That would be preheating like I always do, and full bore, no 
profile, rip through 1st into 2nd, pull before it hits 3rd :).  I 
have done 20 oz at a 15 min controlled profile and routinely 16 oz 
right now at 13-14 minutes (my choice, not the roaster's).
