    Haha - Bean Cooler Mk II

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Well, following the brief discussion in this thread I set about building the new bean cooler.

    I was mulling over where to get a vacuum or leaf blower when the significant other pointed out that there was an old vacuum cleaner collecting dust (ironically) at the back of a cupboard.

    It must be about 30 years old and isnt used anymore so I tore it apart. Mounted the motor inside a bucket with a colander that I chose especially to fit the bucket so its a good seal.

    Its about a quarter the size of my previous cooler so it can be stored on top of the BM which helps when Im carrying it all around.

    Anyway - you all probably want pics so here you go...





    And inside...



    Anyway, so I did a quick 600gm roast of Mexican Altura today and the first cool was incredibly successful. Beans were able to be touched within about 30 seconds and were outright cold in under 90 seconds. Sounds like a boeing taking off though. Originally I forgot to drill the exhaust holes in the bottom and it scooted around my kitchen floor doing an imitation of a hovercraft.

    Bit of a long post for such a minor upgrade but Im really happy with how it turned out. Big thanks to Thundergod for the concept

    Does that plastic collander get soft from the heat of the beans?

    Doesnt look like it. I can see a couple of really small marks where the beans have made contact but theres only 3 or 4 of them and this was with the beans sitting in the collander for 5-10 seconds before I turned it on. It cools the beans so fast they dont get a chance to melt the plastic

    Youre welcome.


    Be careful of that plastic colander though.

    I use a metal one in my currrent setup which works well (although Im going to drill a few more holes in it).

    I suppose if you make sure the cooler is switched on before dumping in the beans you will lessen any potential problem.

    I was a bit apprehensive but it just fit the top of the bucket so well. It pretty much creates a perfect seal just by virtue of the shape of the colander. Anyway it worked well today so I think it will probably be alright but Ill keep an eye on it
