Thought this might be of interest.

Anyone stumble over this before?

I hadn't seen that before. Thanks for posting it.
I'm guessing that Joe is an engineer, not an artist or designer even though he calls the project "industrial art." An industrial designer would know the true meaning of the Bauhaus phrase, "form follows function."
By the way, somewhere here on HRO there's a thread about bowl or centrifugal roasters. |

I think he's fixated on 'feeder bowl' technology. Maybe he will add the vibrator later..I predict it will work very well, but at a very large cost. I would just buy the Ambex and get on with it..but then he's already done the roasting/ coffee house thing..he just wants to see his ideas in steel...

I hadn't thought of that. It's been a long time since I've seen a vibratory feeder in an assembly line.
I can appreciate being fixated on something. Isn't that the description of a hobby!? |

Maybe wew could feed a stream of beans up the sides and roast them one-at-a-time as they go over the edge...

I think a CO2 laser would do the trick! It's beam is pure infrared. |

interesting,
Nice to see another mechanical fluidbed. I can't quite figure the complete design though.
The giant Probat saturn is a bowl roaster but I've never seen one or seen much for details on how it works. Green Mt. has one and used to give tours but no longer do.

It's not a fluid bed, although the beans are tossed back into the center of the bowl, but by centrifugal force, not by an air flow. These also go by the name centrifugal roaster. I'll post two pictures of them.
Joe gives so much blow-by-blow detail that it is difficult to understand what he's up to. And, I don't see any easy way to go to his first entry and begin reading there.

And the innards...
When the bowl is lowered (that's the reason for Joe's four linear bearings at the ends of the aluminum X frames) the beans can spill over the top and down into the cooling tray.

I didn't go back far enough the first time. Yes, centrifugal to move the beans into their deflector fins. I temp. fashioned a couple fins on my roasters walls shortly after I built it and they did work pretty cool, were actually overkill in my roaster, and added noise so removed them. I use my bean bats that create the centrifugal lift they use by spinning the pot. They also use the same style speed control gearhead motor. They are really nice.
This will be cool to follow to finish
