    Yeah,

    Once I take delivery of the thermocouple it will open up a lot of experimental possibilities.

    Update on my basin cooler - worked great tonight with no issues with plastic etc even though a few beans did sit around the edges. Also cooled remarkably quickly and extremely quietly.

    Grendel - Re the rotisserie - there is a great thread on this very topic somewhere in here that had Andy and a few others doing exactly this. From memory, one of the drum was hand made using an old coca tin with wire mesh etc. The chaff was allowed to just drop to the floor of the oven and tipped out at the end I think.

    Keen to hear your progress and Ill post mine

    cheers

    Im eying off a small toaster oven with rotissarie for $70. Would need to have a proper chamber made for it - and not sure how to handle the chaff.

    First off - thanks for all the praise - much valued considering all your varied projects.

    re the heat - the beans only generally sit on the aluminium mesh and not the basin (pretty big surface area) - but the basin is rated as boil tolerant plastic so if there was an incidental touch, I doubt it would matter much.

    cheers

    PS - currently eyeing off a vertical chicken rotisserie from Big W - currently on special for $25 - only issue would be the need for either anchoring the free end and flipping it on its side or putting in some form of corkscrew blading in the bean tin.....hmmm the possibility for welding something is very enticing

    Well I think its great, even if the beans do burn the plastic, it serves the plastic right!

    Looks great Jaxxx!

    Any problems with the hot beans and the plastic? Ive always steered clear of plastic in my bean coolers as most of the plastics out there will melt and/or impart their nasty flavor to the beans due to how hot they are straight from the roaster.

    Great piece of work there jaxxx,

    Nothing like a purpose built, custom made bean cooler to do the job properly ;D,

    Well after seeing the exhaust fan mods, Ive abandoned the luftcooler and moved onto my own exhaust fan - $19 for 250cm fan, $5 for the plastic bowl, and $1.70 each for the 3 door stoppers that provide cushioning when cooling those big batches (actually completely unneccessary but I have always been a fan of over-engineering) + some aluminium mesh - the look on my wifes face when she saw it sitting on our bench - priceless. ;D

    Here it is in all its glory.....


    PS. 30 minutes to put it together with a few bolts

    If week mod your intake tube we could deliver freezing oxgen from a cylinder of liquid oxygen, right near the base of the popper......
    I just have these visions of an oxygen fed conflagration spitting firey coffee beans like meteorites in all directions. . . .

    hmm how would you cool your popper by blowing cool air underneath? shouldnt you blow cool air from the top?
    The air intakes for a popper are underneath, so the popper operating temp is reduced by cool air flowing into it. A bit like an intercooler on a turbo car.
    We have the bling factor and now the intercooler factor.... but yes Lovey is right in explaining it that way :-)

    Phase 2

    This weekend I am building phase two of the bean cooler.

    Phase 2 is using the exhaust air from the cooler to feed cool air to the popper to make sure it runs as slowly as I can manage. Basically I will build a channel down to a flat pad of perforated MDF on which the popper will sit, cool air blowing up from underneath.

    I COULD acheive this by buying a laptop cooler for $34 from Dick Smith Electronics, but where would be the fun in that? Im thinking of making it big enough for two poppers side by side. . .
