    1. the plastic hose starts to suffer from heat and will suck itself closed (implode) and then does not suck fast enough. To over come this i made the hose very short (10cm) and it worked pretty good for a while.

    2. the motor on mine had a thermal cut out and back to back roasts would trip it and the motor would stop mid cool and you have to wait a while to it to cool down to restart. To overcome I removed the thermal cutout.

    the third step in my cooler evolution was to take the motor out of my vacuum and attache it to the bottom of my "cooler" its still inside the "inner" plastic box but just crewed to the bottom of my cooler inner. now there is no tubes or big things sitting around as i mounted it inside my roasting bench
    Similar evolution to mine.

    However, I didnt have problem number one because my Sadie industrial vac has a hose 4 times normal diameter.

    Problem 2 also didnt eventuate probably because my vac was industrial.

    My new cooler does now have a vac motor inside the bucket.
    This gets rid of the hose in the setup.
    My sieve sits perfectly in the top of the bucket so is simply lifted out to empty the cooled beans into my bagging scoop.

    but not nearly so good if it is turned over to blow up thru the bucket, in that the motor is then above the blades and there is very little airspace beneath the fan
    You just need something to lift the fan...

    Hey Borat thats a great cooler, i used the same idea but have since modded mine a bit more.

    I had two issues with the same set up, for anyone else considering a vac bucket setup may want  to consider my issues.
    1. the plastic hose starts to suffer from heat and will suck itself closed (implode) and then does not suck fast enough. To over come this i made the hose very short (10cm) and it worked pretty good for a while.

    2. the motor on mine had a thermal cut out and back to back roasts would trip it and the motor would stop mid cool and you have to wait a while to it to cool down to restart. To overcome I removed the thermal cutout.

    the third step in my cooler evolution was to take the motor out of my vacuum and attache it to the bottom of my "cooler" its still inside the "inner" plastic box but just crewed to the bottom of my cooler inner. now there is no tubes or big things sitting around as i mounted it inside my roasting bench ( which looks just like your bench  :-?)

    they are a bit loud but :

    down side is no more vacuum cleaner...... but it was a curbside freegan anyway....

    Re-use the sieve from your pasta pot set, steal the wifes vac, a bucket and youre right to go. Cools the beans in only 30 secs...

    I have always blown mine using an 18V leaf blower.With 500gm of beans they dont blow away but they are cooled in under a minute.Smaller batches I use a splatter guard to stop the beans blowing away.
    Not a bad job barrel

    I am somewhat restrained with most of my designs

    My wife wants neat & tidy units that can be stored away

    I want plug & play functionality

    So I try & marry the two together

    Ive also been looking at an extractor fan with friction fit in a bucket (both quite cheap from bunnings). The fit with the fan "extracting" is very neat, but not nearly so good if it is turned over to blow up thru the bucket, in that the motor is then above the blades and there is very little airspace beneath the fan.

    My (electrical illiterate) question is; can the direction of rotation of an AC motor be reversed in some reasonably simple manner?

    I think I had now better toddle off googlewards

    I have been using a standard fan for cooling but for a while have wanted to go to an exhaust fan turned around to push, a sieve and bucket...keep the pictures coming folks!!

    Cheers

    Stainless food grade sieves available on ebay

    $31.80 with free postage to Australia
    I explored the Bay of Evil and also looked at prospecting sieves but all were too expensive.

    I got my fine mesh sieve from the local $shop for $5.

    My father in-law has given me a gold prospecting sieve and thats what I use now
    However it is a finer mesh than in this photo



    The wife wanted her steamer insert back : for cooking of all things

    FWIW, those "geology" sieves can also be found at bee/honey suppliers along with good food quality plastic pails but both are probably a little more expensive there than than most would want to pay for a bean cooler. I have 2 which I use in extracting honey but unfortunately they wont be living with my nearing completion corretto

    Ill have to take some more pictures of my setup.

    Consists of a 60L plastic garbage bin from bunnings - $9
    Cheapest 25cm exhaust fan I found in bunnings - $15
    Sieve from hot dollar - $4

    Cut the hole in the bottom of the bin which was easy as the rim at the bottom was 25cm.

    Cut a hole in the top.

    installed fan blowing air up. Installed the sieve. Works great. Cools 500g of beans in less than 60 seconds.

    Only thing is I have to sit the bin on some bricks to give it ground clearance. But thats not a problem.

    My setup (of the last few years) comprises a generic bathroom exhaust fan providing positive pressure through a 300mm sieve and has never looked like tossing any of the beans out. You guys must be using industrial strength blowers for your coolers....

    Mal.
    Yeah, somewhat similar to my setup, and I also have never come close to blowing beans out.  Also even with the positive pressure setup I am seeing some buildup of muck on the top of my fan motor, would be interesting to compare motor condition after a few years of suction, compared to a few years of pressure.

    BTW I use a splatter guard from the kitchen ware section as my sieve they only cost a few $ and work very well.


    Bullitt
    I have tried it with fan sucking and blowing just to compare the difference
    Both ways work well
    The blowing test
    The insert I made (build details on post #1) completely eliminated any shooting beans as the cooling  surface sits deep approximately 150mm (6 inches) from the top of the rim so the beans that had the impetus to jump did not find freedom they just fell back down to rejoin their mates

    Re: Bean Cooler and Insert for 20lt Bucket...

    Interesting stuff guys, my fan must be the turbo version, :P I have been thinking about the temperature change initiated between positive and negative pressure setups ie pushing as opposed to pulling air through the beans , so Im gonna try both with my thermocouple and see if I get any difference, btw, I have also thought of the resistance on the fan motor of both setups , and that might be something for someone a bit better with a multimeter, as backpressure on a negative displacement fan can be a problem as can reduced airflow from too many beans in the sieve.Hey Bullitt I just saw what a splatter guard is, would be a good alternative, the sieves were sold to me by a slightly unscrupulous camping store sales person when I was actually after a gold pan.. found out later they were for sieving rocks and have sat in the shed for 5 years collecting dust until two days ago.. Ill have to offer the shady bugger from the camping place a cup of coffee as payback [smiley=beer.gif] Cheers Gaz
