Thanks for the addition to the group. Seriously considering building a drum roaster along the lines of oldgrumpus's. Love the design and craftsmanship.

2kg Drum Roaster Build
directtraderoasting
Here're are some photos of a 2kg drum roaster I built last year.

Quick Specs:
-Single blower for cooling bin and roaster air
-60rpm drum speed (going to change the gearing to up that to the 64-68rpm range)
-Manual air flow damper to control roaster air (coupled with a Dwyer Magnehelic)
-10"OD x 12" Long drum (.120/3mm drum thickness)
-(2) 2 mm thermocouples hooked up to TMD Amprobe + Artisan

Not much else to say about the build. The next one is going to have a thicker drum and I will work on truing up the front so the gap to the front faceplate is more even....but that'll wait for a while until I have the time.

Having trouble getting the photos to upload, but here is a link: https://photos.ap...3S5qGDPom7

Nice work on the roaster!

Posting photos: I find that scaling the size of the images down to 800X600 for web viewing sometimes work better (I know it says max filesize 10MB). Try to keep the filenames simple.

Let me know if you are still having problems with attaching images.

Thanks! And thanks for the tip on the images.

I love the colour!

Did you make the bean hopper, or did you source it from somethere? I've tried making one, but don't have the tooling to roll the edges, so the end result is not as refined as I would like.

Nice roaster! Great job on it! Looks like it will roast many many batches of beans!!!

Thanks! I actually bought the bean hopper and just welded it on. Pretty much the only metal part aside from the drum I didn't shape.

That said it was a seller on eBay and I they've been out of stock for a few months now. They do have one with a a smaller opening that could maybe be modified. I'll find the link today.

Next time I'll likely try to make a hopper if that seller is still out of stock.

Thanks! I've roasted a decent amount through it so far and it's doing well

Your roaster looks sharp!

Did you design your own burner?

Sort of. I had a tube burner setup of made and played around with making orifices and dialed it all in.... Then it was really under powered for what I needed. I ended up ordering a big 10" round burner which works well.

I tried to attach the photos from my phone of the tube burner options. If they didn't attach, I'll add them from the computer tomorrow.

If/when I build another, I may make my own custom burner.

Attempt 2 at the photos

I added some burner photos to the album in the first post.

I'll add pics of the burner I bought shortly

Looks like a brilliant option. I might end up going in a similar direction if I can't get my electric heater element going.

Another quirk with the forum software I forgot to mention: Don't use preview post or preview changes when posting photos, it will wipe out the attached photos.

Thanks for the tip.

Here's a little video walkthrough of the roaster:
