Hi, I have been so satisfied with my Hearthware home roaster that I purchased in about 1997. This original unit is not even commercially available but it works just fine. I am thinking about purchasing a scale-up unit and have looked at info about the Sivetz fluid-bed roasters that many small commercial operations are using. The claim is that the aromatics in the roasted bean are preserved using fluid-bed roasting rather than convection heat due to the lower temperatures, and also that there is less carbonized, burnt flavor in the beans. Could someone tell me about the prices and what is available for larger fluid-bed roasters? I would prefer an electric powered fluid-bed unit. Thank you, Fiona Geiser
Fiona, Have done some research on this. Check out sonofresco.com.
It's just a claim. Another claim is that air roasting roasts too fast and does not give the bean enough time to develop flavor. Both claims are hogwash when beans are roasted properly in any competent machine. ********************* Ed Needham "to absurdity and beyond!" ed at homeroaster dot com (include [FRIEND] somewhere in the subject line of any email correspondence) *********************
Found my notes--Sonofresco is $3500.-uses gas for heat.
The Sonofresco may be the least expensive 'commercial' fluid-bed roaster at roughly $3500 from the manufacturer. It's an attractive idea, a 1 Lb, fully automated, table-top device - which, with its optional vent hood could realistically be used indoors. BTW, I believe that the Sonofresco and the Monster Coffee version use 110V for the control circuits, but roast using Propane from a bottle. Unfortunately, the basic machine has been through several versions and manufacturers - and has gotten a reputation for being somewhat fussy and unpredictable to use and for having expensive and difficult to obtain parts - specifically the glass roasting 'carafe.' I don't know if the current production has improved the situation or not. The small Sivetz roaster as shown on their website may not be in production any longer - at least several requests for price information have gone unanswered - it used to be about $2200 several years ago, which seems at bit expensive for what is essentially a kit which you have to complete The 5Lb Sivetz is about $6500 and there's a 12Lb version on Ebay which has gone begging for several auctions, but is expensive. In wandering around the 'net, I did run across this small 'pearl' of wisdom from a little-known coffee reseller:http://www.sweetmarias.com/tiny_joy_html/tinyjoy-augsept-03.pdfAlso, you may want to consider the upcoming Gencafe roaster - it uses a rotating drum and pressurized hot air to roast- its getting good press in Europe - and should cost about the same as a Hot Top. I think that Tom may have some more information on this device. It's very frustrating - my Alpenrost is slowly dying, and I'd like to replace it with a table-top machine which could reasonably roast 1-2 Lbs batches and (if necessary) do several batches per day - but suddenly the price delta for increasing the batch size is appears to be an order of magnitude - jumping from $350 to $3500 (and up) in a heartbeat. Yeah, I know that this class of machine is intended for commercial service and is built to last forever, and has nifty features, and is haunted by the ghost of Jabez Burns himself, and yadda, yadda, yadda - but 10x the cost? Mutter, mutter, mutter Look, I'm not alone, and I'm not asking for much - Just a Hot Top Senior, or an RK Junior Drum in an assembled machine - one has to wonder why this hole in the market continues to go unfilled. Cheers Jim
Jim - 1 to 2 lbs, you say? OK, consider that my target range for a project I'm embarking on. Details once a prototype is in beta. ;-) I'll only hint that it's going to be a bit unusual. Seconding Ed's remarks on claims and performance. Since extending all my popper roasts to any duration I want (I generally run between 12 and 16 minutes), it's been easy to see that the "too bright" thing is from duration, not method. A drum would probably be bright too, if it were sane to do 7 minute roasts in one.
From comments I've read on the Roaster's Guild board, the Sonofresco is fragile and the companies that support it are difficult to deal with. You could do better by not sinking your hopes into that particular machine.

I hasve purchased coffee in the past from a guy who uses a sivitz roaster and he swears by it, if i were starting a roasting company(which i and i be= t all of us would love to do) i would get a diedrich drum and a sivitz roaster, as each has different qualities and beside the geek in me would think it was really cool!!

In response to that article, Thunder Brew Coffee Roasters uses a couple of Sivetz machines in its Crivitz, WI operation (combination espresso bar, roasteria and retail store in a "manufactured housing" building. Its stock in trade is roasting batches of 1/4-1 lb. to order while you wait. Dunno what they use at their Algoma headquarters. Kate of Marquette, MI's Dead River Coffee (who uses drum roasters) tells me there have been instances of fires in Sivetz roasters, at least one of which took down an entire building.

I would like to know more about the Gencafe mentioned. Anyone have further info or links on this new item? MJB
Mark - There's a fairly long-running thread over in the CoffeeGeek site - go to 'forums' and search for 'genecafe' - note that I misspelled the name in my post. Cheers Jim
