B-A-R heating element

Anyone built a Bake-A-Round roaster using a 120 v element?
Thanks

Shoot us some details on your roaster and how you're using the bakearound
1/2 lb and 1 lb drum, Siemens Sirocco fluidbed, presspot, chemex, cajun biggin brewer from the backwoods of Louisiana

I built mine with the Bake-A-Round, a martini glass, 1550W element and 250W vacuum motor (it's all controlled via a TC4+ board and Artisan).

I had a difficult time balancing the fluid bed movement with heating temps...more airflow moves the beans better but drops the inlet heat. I downsized the glass tube to something 1/2 an inch smaller in diameter and that helped some but I still think heating element is underpowered for the roast chamber and fan motor combination

You can definitely make it work like that though...Before I added the TC4+ board and began roasting via software, I got some nice roasts by manually "pulsing" the fan off/on every few seconds so it would keep rotating the beans while also increasing the heat but then your ability to repeat a good roast is impossible.

Thanks. Sounds like you're using the same thing I have in mind. I may have to re-think this setup.

Any pictures of your roaster?

I haven't shared anything yet for pictures or videos but here's something I had earlier.

It's design was inspired quite a bit by CK's transparent roaster (https://homeroasters.org/forum/viewthread.php?thread_id=5742) and the Roastino (www.cyberelectronics.org/?p=699).

I really just threw it together with parts laying around the house and everything was press-fit together with silicone tape so it's safe for high temps and easily disassembled

  1. dirt devil vacuum motor
  2. heat gun
  3. martini shaker
  4. Glass tube
  5. sink/garbage disposal mount



...later I added two of the "tornado dust separators" like in CK's build and the copper tubing to recirculate the hot air and separate chaff but ended up abandoning that idea.


I think this is still a viable build but you may have better luck with some Tri-Clover parts and a smaller roast chamber...the Bake-A-Round is big enough to handle 1-2lbs batches from what I could tell but a 120V element isn't going to heat it well.
