Gas Fired 1 lb Fluidbed Build

Here's end of roast. My daughter ran off when the camera got too close.

Hi Allen
How are you cooling/dumping?
Now while you've got the camcorder out throw some beans in it. BBQ grill

Rob,

I made the combustion chamber out of a tin can so there would be very little thermal mass. I'm able to cool in the RC and BT drops down to around 200F in 2 min.

To dump I just pull the two springs and lift the RC out of the well and tilt carefully. (I've almost broken the glass a few times now). I'll probably build a sheet metal RC pretty soon.

Very cool, I assume cooling is done in the RC? I tend to roast with faster bean movement, not to say there is right or wrong way.

I've roasted with quite a bit more lift as well. Didn't notice much difference in the cup at least with this one. Yes, I cool in the RC and it's very fast luckily.

BTW Rob, thanks bunch for the help with the RC layout, works fantastic!

Very nice! You're happy with the stability of the flame?

Hey Scott,

Yes, very happy with flame stability. At maximum cfm I can take the flame down to just barely visible and no flame-outs. I have to take gas pressure to around 8 psi for easy ignition and then bring it down a couple of lbs to be able to start the roast with an ET in the low 300's F.

My next mission is to find a reasonably priced, very fine threaded needle valve to be able to accurately dial in rate of rise. It's presently over and undershooting more than I can live with.

Absolutely awesome.

Great work,

I am jealous.

Thanks James. This was one of my more enjoyable builds. Especially since I didn't have to try several versions of the different parts. It was done in one "take" since Rob (RoasteRob) already did the R&D.

Amazing build, extremely compact and clean. Any plans for PID'ing it?

Thanks!

Yes, I'll be experimenting fairly soon with PID automation of this roaster using the TC4C and gas control hardware. I'll document the progress in a new thread within the "Dataloggers/Controllers" forum.

BTW, nice engineering on your fluidbed dump gate. Looks like it performs the task very nicely!

Hey Allen, the brand is "111ager" sold by Auberins. It is well pasted+screwed to metal chassy, which never got beyond warm. Roaster was fused with 20a buss + 20a thermofuse, neither blew.
