A couple of years ago I decided to start roasting my own coffee. I didn’t want to throw a lot of money at it since I wasn’t sure it would be worth doing long term. After some research and a few trips to the thrift store I decided to make a roaster out of a bread maker. With numerous failed experiments I had a working prototype that cost < $40. When I started I didn’t know if the first roaster would even work so I didn’t bother documenting the build.
Two months ago I caught my coffee roaster on fire. I will not go back to drinking old, stale coffee so I went about building a second roaster.
You’ll notice the design for both Coffee Roaster v. 1.0 and Coffee Roaster 2.0 do not require a heat gun. Most other bread maker to coffee roaster conversions will use a heat gun as the heat source.
Out of respect I’v included a a few pictures of the now deceased Coffee Roaster v. 1.0. Version 1.0 had a temperature gauge and a timer, but neither turned out to be very useful.
