Ikea inspired DIY home coffee roaster
Thye
Hi fellow home coffee roaster,
Thank you for the add. I started to learn about coffee roasting 3 years ago, and has been crazy about it. I DIY built a drum roaster myself in my own garage using parts purchased from Ikea and hardware store. The main drum used is Ikea ORDNING Colander and other body is Ikea SOCKER Bucket.
Here is a recent video of it in action. Apologise for the poor video quality, first time trying to make a youtube video:

Another one Ikea parts fan here, using Steamer insert, product code 301.523.46, for both innermost pan of roasting oven, and also as external cooling tray.

Another good drum candidate could be STABIL pasta strainer, cod 702.389.99

More details about drum/internal build? Any vanes ?

Yeah when I build the cooling tray 2 years ago I didn't have a clue what I am doing. It might worth an upgrade soon. I am planning to write an instructable. I will try my best to put in as much info as I could because I did not document my progress during the build. I should have I know...

For the next iteration, my idea about a dream roaster is to have the whole front plate made from glass ... :)
What if you would replace the actual tin cover with a glass lid/Pyrex? there are fairly simple techniques to make holes in the glass...
Actually you need a single hole for charging/exhaust only. The shaft can be mounted inside.
Drop door approach also can be changed, by replacing it with the whole glass lifting up. You can mount the glass in three clamps at 120 degrees each other, two bottom fixed, at hours 4 and 8, and a mobile clamp up at 12. Release the upper clamp and lift the front glass, coffee drop, start cooling.

Love your creativity and sense of good design. I've got one suggestion however.

The SOCKER bucket is steel, coated with zinc (galvanized). Zinc is a relatively low melting point metal. Your burner will melt and vaporize that zinc, and it can condense on your "cold" beans - possibly not the healthiest thing. The SOCKER is sold as a planter bucket, not meant for food processing requiring a flame.

Most roasters are made of stainless steel, un-coated steel or aluminum. Suggest you stick with those materials for safety reasons.
