Hi Guys,
After first coming across this site 6 mths or so ago, I had my roaster and a vacuum cooler up and running in about a week. I got the general roaster idea off Youtube, a gut called Porky Fedwell. Then its been 4 mths of tweaking, including destroying 3 heat guns, 2 vacuum hoses, 2 heat probes. Ive finally got a rig running for the past couple of months that is reliable and running well.
The roaster
Main parts:
Stock pot from $2 shop - $17
Window winder motot from auto wreckers - $30
Electrical gear and resistors to slow motor from Dick Smith - $5
Silicon bake tray to protect probe - $5
Craft wood - Had it in shed
Heat guns - Had one, got ryobi $45 off ebay ( bought 2No. $20 cheapies from Aldi, one died on its first roast, one caught fire soon after, bought another cheapy that died after a few roasts )
MDF for main body - Had it in shed
It roasts really well I think. I have roasted up to 1.5 kg green in it and bought it to first crack in around 10minm, although I now usually roast about 1kg green, which is ideal. I get to first crack in about 8 mins, I then kill the drum heating gun when the heat starts to run away a bit, and move the other gun back until I get about 3 deg/min to second crack. When finished I hit the stop button when the handle points up, and just tip the whole unit up and into a colander, then into the cooler :
Parts
Ceiling fan - Donated by my dad as he had one in the shed
Flowepot - $2 shop - $10
splatter guard - $2 - $2
Draft seal - Hadit in shed
I put this unit together with what I could lay my hands on, after a look tonight, I was suprised to see it is very similar to some others posted on here. I originally had a vacuum model, but after upping the roast size to i kg I couldnt cool quick enough, and started having problems with melting hoses etc, so went ceiling fan. This is totally air tight as I weather stripped it, when you dump a full load straight in, it nearly stalls the fan, I usuall just feed it in a bit slower - it cools in 1-2 mins. Again, I just upend it, and the beans drain through the handle hole into a colander, then bag it.
Id like to thank all the posters on here for the inspiration and ideas, and the coffee is great!!!
