peveleth, It is better if you start a post in the forum with your question. These shouts go away in time.

For Gene Cafe Roasters I have an older Gene Cafe Roaster. Temp fluctuates probably showing age. Question: For recent owners of the newer Gene Cafe Roaster, your opinions?

Morning Ed, I haven't done any green coffee hoarding yet but am hoping the supplies don't end up like the toilet paper isles!

The site is working fine for me. I have to say the price is reasonable at US $3,947 if it can roast 5 lbs properly. Nice find!

The price is right to me, too. I have to laugh at the use of off-the-shelf components like restaurant food funnel RC, colander cooling pan, and mixing bowl vent hood!

I don't see how this could be called a true fluid bed since the perf plate doesn't go all across the bottom, but just a small portion. A true fluid bed does not have a funnel shaped bottom. While watching the beans in the video, this is clearing a spouting bed; just the central portion is lofted while the perimeter is sliding down the funnel sides.

I can't tell for sure, it seems to only have an on/off digital thermostat. If so, then no programmable profiles. That's pretty sad since it makes using it more difficult. And, since PIDs are about the same price, a dumb move, too. The first modification I'd make is drop in a Fuji PXR3.

Hey now!!! A conical fluid-bed is still a fluid-bed! :)

I think the proper term is "spouting bed" if I am not mistaken, correct Dan?

Its all become a bit genericized.

Freshbeans, Well, its a type of fluid bed, I agree, but note that OGH made the claim that it was a TRUE fluid bed, which is what I disagree with. We are a technical group and I think posting non-ambiguously is something to strive for.

Len, Yeh, its a spouting bed and I think that is the right term for this type of hot air roaster.

Yeah, what is a false fluid-bed? I've tossed that around in my head before (plenty of open space in there), while looking at incinerators and such. Clearly those machines seem to have everything fluidized...all the time. Yet, gravity is still part of that equation too.
It still seems to me that velocity pushes up...gravity pushes it down. It moves like fluid, and gravity is doing half the work...regardless of whether it's spread out or stacked up.

....but I digress. I've never actually seen this machine before. How long has it been out there? -Scott

OGH said it, not me!

Feshbeans, I think you are right. a fluidized bed, strictly speaking, has the entire contents of the chamber lofted all the time (keep in mind that the goal in such beds isn't to aid in mixing or particle movement, but to keep the particles from clumping). But this isn't what's happening on most of our hot-air machines, nor would we particularly want to do this. That's why HRO members came up with the term "spouting bed" in order to distinguish what we were seeing and designing toward. In a spouting bed, a small portion of the bed is lofted, either a central column, or a column along one side of the RC. I don't think I'm the only one who feels this is an important distinction to make. Verstehen Sie?

My biggest concern is how I've never seen this machine before!! I kinda like it, but I'd like to see under the hood. Did I overlook a schematic?

(Yes, distinguishing is important. This is why I still distinguish between conical and asymmetrical sprouting beds.)

Cheers, Scott

Here is a decent analysis of the methods of roasting; spouting bed is included:

I recall that Sivetz had a summary of the different types of fluid beds on his site; unfortunately his site is now gone.

I was surprised by the paucity of information about their only product. And, there isn't a lot of transparency on the site. Not a single person's name or photo. The website is just 15 months old. When I combine all that with the fact that no one at HRO has ever heard of this roaster, I wonder if they aren't selling vaporware. I wonder how many units are actually in use.

I've seen it on eBay. I think they sold their prototype about 9 months ago on the site. They may still have a listing there. A couple feedbacks indicate use purchases. My main concern about the unit is how well it handles roasting smoke evacuation. Such an open air roasting process could create some interesting problems to address. I was using a similar smoke evacuation setup for a wood gasification heater I was experimenting with; the smoke removal did not work well. Applying a similar method to a coffee roast where the desired roast was a darker type like vienna or french would likely overwhelm the smoke removal processor and cause the roasting room to rapidly fill up with smoke and carbon monoxide. thumbdown

This one has been around for a few years and at first I thought maybe they gave it a face lift and paint job but not the same outfit.

Len, I was curious about that, too. I noticed that the vent hood is smaller than the RC. It is common practice to make vent hoods larger than the smoke producer. For instance smoke hoods for a gas range are typically 6" larger all the way around. I guess Coffee Crafters couldn't find a mixing bowl large enough! Roflmao

Say, let's ask for a test unit to review! Send it to me. I have a loading dock and the electricity in all sizes and flavors.

Because of the new forum I looked at this semi-old thread.
This caught my attention.

"This roaster can be easily installed, with training and proficiency in less than 30 minutes! Roast times/cycles are less than 5 minutes with the smaller quantities, and less than 10 minutes for the five pound maximum. "

Does that mean this machine has no capability of adjustment of heat? Or simply a statement of capability?
