  • Birth of the Bruce

    After months of chatting, designing, scrounging and some seriously good metalwork, our proverbial old-metalworker-next-door has just delivered our roasting machine - The Bruce (named after its builder). It is a stainless steel drum over a bbq burner turned by a wiper motor. First batch was 300gm Brazil roasted to a very even CS9. Now we just have to be patient enough to enjoy it at its peak. I reckon if anything the batch was a little small for it; looked like it was crying out for at least a half kilo.

        Thanks Matt

        cameras on the blink at the moment, but should get some pics up soon.

        In reply to your question re noise on another thread, I think its from the rollers at the far end of the drum from the drive shaft. Rather than a bearing like yours, mine has a pair of bronze rollers. Did you have to get a special heat-tolerant bearing?

            I didnt get a special bearing, but I asked about heat when I was at the bearing place and they said it would be no problem.

            I am planning to try and look up temperature tolerances for this brand of bearing.

                    Thanks Matt, We did one of around 600g but beans were being thrown out. However, now that we chock up that end of the stand a little it seems not to be a problem, so will try a big batch soon. The new rollers, with ball bearings, are much quieter, so now it is just the whir of the motor and the rattle of the beans.

                        what are your thoughts on perforating the drum?

                          Re: Birth of the Bruce

                          I perforated the drum in my current roaster myself by wrapping some thin perforated metal that I found around my drum and using it as a drill guide. took a long time.
                          I dont know a lot about the difference between roasting perforated and non perforated though.

                            Our roasting times are quite long: 20-24 minutes versus the 12-18 minutes we were getting in the cast iron pot we had been using. Just wondering if this is normal/desirable, and if not, would perforations help. I guess they would assist in the escape of smoke and the burning off of chaff.

                              From the video I saw... The rotation speed is somewhat faster than I expected and teh beans seem to get LOTS of movement and tossed into the air?

                              If you look at a HT.. The element is on one side - not the bottom, and the beans tend to sit; due to speed and gravity, on the bottom/ other side and under go a rolling motion....

                              Even very old mechanical ones with burners etc did not rotate that fast...

                              Not sure if you can slow it down, and manage tipping etc (Heat / Burner positioned at about 8:00) but my gut says that the speed is causing you heat loss. If you did slow it down and could roast a bit quicker... Also a saving on Gas
