Popcorn Popper Roasters

[peter]

The slit silicone tube is pointless IMHO; the top can't slip off, only go bit off-center, and in a matter of a half-dozen roasts the roastium build-up, in an uncleaned roaster**, on the glass top will keep it from slipping too.

FIFY

**Not a problem if you like filthy coffee?

Cleaning the glass helps nothing but being able to see the coffee, nothing to do w/ flavor, and you know it.

So where do you get the metal used as a spacer?

I bought mine at Home Depot.

So where do you get the metal used as a spacer?

I buy this at Ace Hardware - 1/16" x 1 1/2" x 4'

1/16" stock is a lot easier to form into a circle than 1/8" stock, and cheaper.

Do I need anything else to add the spacer to release chaff?

Folks differ on their approaches, but I get good results from this. Not shown is the foil I put on the bottom of the chute, which I remove at the end of the roast to dump chaff into a colander.

What makes the shute?  Is it a bracket or just the metal strip bent?  Did you weld it shut or something?

Isn't 4ft a little long?

It's a piece of the left-over aluminum bar I used for a riser that I cut & shaped to fit, then pop-riveted in place. I filed it at an angle so the CO top would fit snugly. If I was doing it again I'd make the chute a lot smaller.

The two notches are where I fit the two thermocouples for the data logging digital thermometer I use.

What is it you are trying to show me?

Found strip at Lowe's. Now what?

Form the strip so it sits on the stir popper, then cut it to length. I'd begin with an overlapping joint; no chaff chute (chaff can be easily vacuumed up after the roast). You can always get as creative as you like after you've been roasting a while.

The video shows how I place the thermocouple so I can monitor the bean mass temps.

Which corn popper did you buy? There are modifications that need to be done for each of them.

This will (again) make me sound like a pompous ass (I'm happy to endure that title to help a n00b create their roaster), but look at the spacer/chaff ejector I use;

It's simplicity in action; no pop rivets needed, can be opened or closed to release chaff or modulate heat, and just flat works.

Tex is absolutely correct, that the 1/16" thick aluminum is the way to go.  1.5" high is good too.

This is perfect! Thank you Peter.  This does not make you look arrogant

I got the same metal as Tex. Home Depot had nothing close.
