I'm getting ready to build a coffee roaster, my first. I've got it put together in my mind, though my plans are subject to change. In fact, there subject to a lot of change. This coffee roaster will be my first serious project, and I haven't ever really worked with metal, but I'm an apt learner :)
Some specifications:
- Half-pound capacity drum roaster. I have an old stainless steel cutlery holder from IKEA http://www.ikea.c.../30011832/ It's about the right size for what I want.
- Electrically heated
- Made with aluminum. I chose aluminum because from what I've read, I can work it with the tools I have (a handheld jigsaw, electric drill, some hand tools). Also, it's cheap :). I do have one worry though. If I were to build the roasting chamber out of aluminum, would the heat degrade the aluminum's structural integrity?
- PID. I have an arduino that I'd like to incorporate into the roaster.
Suggestions/comments/criticism is much appreciated.
Hi I am also just beginning to think about roasting. No doubt my idea is impractical. I have a rotisserie in my oven, if I were to fit a large tin on it with holes and a couple of baffles could that work?
The drum should be a min of 3 to 4 times larger than the maximum dry/green beans the roaster can roast
This is to accommodate the doubling of the bean size by the finish of he roast and plenty of room for he beans to mix
The heat available should also be ample enough to do the job in comfort

A short answer
NO an oven rotisserie will not do he job

The cutlery holder is bit short, maybe you can use stand for utensils: http://www.ikea.c.../30131716/
It will give you more capacity.
The holes are quite large and will need covering with a mesh or perforated plate.
Do you have Tchibo shops in your area?
They have round SS pot stands with diameter suitable for Ikea holder.

I can attest to folks being out and about. Me and Julie were out hitting the garden centers for loading flower pots all day. Nice weather! Tomorrow the Kamado/egg gets fired up!
