    Re: Its the Cooler for you Herr Grendel

    Love them both - me, Ive been using a large area fan the conveniently twists flat to have my splatter mesh sit on to - it generates enough airflow that the mesh with the beans will actually hover over the fan if you let it. ;D

        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. . .

          Grendel, youre out of control... I like it :-)

          Laptop cooler sounds like a good idea actually, I need to cool down my popper as its roasting too fast I feel...

            Just saw the laptop cooler last night in a catalogue - and immediately thought of colling beans or poppers with it. It would make and excellent low profile bean cooler.

              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.

                  If week mod your intake tube we could deliver freezing oxgen from a cylinder of liquid oxygen, right near the base of the popper......

                    We have the bling factor and now the intercooler factor.... but yes Lovey is right in explaining it that way :-)

                      I just have these visions of an oxygen fed conflagration spitting firey coffee beans like meteorites in all directions. . . .

                          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

                            Great piece of work there jaxxx,

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

                            Mal.

                                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.
