Halogen Radiant Roaster

Electrical wiring is protected by an aluminium cover strip which clips snugly over the main aluminium support beam

There was a question earlier about buildup on the lamps. I can confirm that not only is there no buildup on the lamps, there is none on the reflectors or the mounting bracket either. Obviously the temperature here is too high for deposits..:@

The lamp dimmer controls from 0 to 100% power (this is lamp test at dim - can't look at the lamps at full noise!)B)

The end of the reflector shield is about a half-inch from the back of the drum. This view also shows the offset of the lamps, which covers the position of the bean mass as the drum rotates CW.

Took it apart some, put it back together, still works like a charm! Grin(phew!)

BTW, the reason I hung the drum from a top beam, rather than a bottom mounting, is so that I could slide a tray under the drum for dumping (obviously!)

Any questions?

what great photo's
what agreat roaster
thank you
this I will try to build

the bean

aka katee

I thought that I had better get around to posting a picture of my working setup including the bean cooler (alas, too small for the competition!)
This uses a 4-inch bathroom extractor fan, and includes a chaff filter and bagging chute (and makes a nice stable base for the roaster).

I like the fact that I can cool the previous batch and roast the next batch at the same time, all self-contained.

Terrific engineering and sheet metal work!!!s:2s:1s:2s:1s:2s:1

No air flow hassle, less cleaning.
This needs to go directly into production. When can I buy one?

Wow, It just gets better and better! Very cool, Brian. s:1

This roaster inspired me to try building one of my own, but it's not nearly as nice as this one. Mine's a bit more of a junk-yard dog. Sorta looks like a home made tow truck on the back of a a '73 F100 pick up...

I'll post all about it once I get a little more time.
Respect the bean.

Nice unit and prototype. How quickly does the 4" bath fan cool one pound? I also roast 1 pound and spread the beans over a 20" fan for a one minute cool. Dan

Brian, I still feel guilty every time I look at your roaster.

I know, it's old, but instead opening a new thread for a question spot on topic, I hope someone still read here,so...

Where would be the most appropriate place for ET probe in such roaster ?
JackH
Check the OP's profile. There should be a email address you can try. He was last on this forum in 2017.

It looks like an awesome roaster. Have you considered using a thin perforated stainless drum? you can source these as perforated stainless waste baskets at Various retail stores. Awesome design.

Opinions from anyone than the OP are welcomed, though.
I am thinking the place for ET should be not exposed to direct radiant heat, so behind the reflector... now wondering how much heat radiates the reflector itself !
