  • Slowing down popper roast

    This has probably been discussed lots but was wondering what mods you can do to slow down a popper roast? Im guessing this has been done before also but what would be wrong with turning the popper off for 30 seconds or so a few times during the roast to keep the temp from rising to quickly? i tried it yesterday and it took longer of course but havent tried cupping yet. Has anyone had any success with doing this?
    Cheers

    Switching off ur popper and not letting it cool will most likely kill ur popper faster. I let my popper fully cool in between roasts so as to maximize the life of my popper.

    Without major alterations (see mrseca popper) it is difficult to slow down a popper.

      Phill that doesnt mean that ur popper cant produce some great roasts!!

      Keep roasting and try allowing ur roasts to go long- let them sit a few days & try them, then also pull it earlier and do the same- experiment a little. Remember its what in the cup that counts.

      Im getting some great results from all origins of beans!

        Phill do a search for the mods I did to my Crazy popper.
        I got it from 5 minutes up to 15.
        No electrical mods - all easy stuff.

        What popper do you have?

          Hey TG I have a Black and Decker popper- what did you have when you cut the top off it to aid in cooling- what this what you talked about above^^^^^ to get to 15 minutes roasts??

            "Unscrewed" the top and added extra input holes for the air to get in.
            Basically that was it.
            I called it adding "thermal inefficiency".

              yeah i got a black and decker also, I think the air intake holes are in the bottom of the unit. I tried the Brazil original roast thismorning that i switched off at intervals during the roast to slow it down, it has made a difference, the brazil roasts i did before were not that nice. But i know if i keep doing that it will kill my popper. So I think i need more air intake, How much more do you reccomend?

                  Take a look at this thread:
                  http://coffeesnobs.com.au/YaBB.pl?num=1155880692/0
                  Theres a picture of the underside with extra holes before I took the bottom completely off.

                  Theres also a picture of my popper in all its blinged glory before I took off the top half.

                  Make sure you read the thread too for some hints and tips.

                  Also has a bit of info but no pictures.

                    Philby how long did u allow the Brazil roasts u had do e previously sit before u tried them?? U Ned to allow 4-7 days before u try them.

                    When I started roasting I never realized this an none of them really tasted all that impressive. Now a huge improvement!!

                        I started cupping some at 4 days and tried it now and then up to about 10 days, it improved slightly but still wasnt great. this last one though has been much better.

                          Dear TG,

                          I wish to mod a popper for coffee roasting.

                          Being an idiot, I would like you to direct me to any photos or clear descriptive work on the mods and results of drilling input holes to get air in????

                            I say use it as is, unless you really, really want to stuff with it. Try keeping a roasting log; I like to keep the ambient temperature, batch size, time to rolling first crack, time to second crack (if reached) and time dumped for cooling. Taste notes come about a week later.

                            I find that with my popper (Black & Decker 1250W) its best to roast around 12C. Any much under that and it doesnt want to get to SC, any higher than 14C and it gets a bit quick. Making it a bit simpler, anywhere between 10~15C seems to be alright, with 12C being optimum.

                            If that doesnt help, then start modding your popper. Thatd be my reckoning anyway, the only mod Ive done to mine is an opened-out beer can as the chimney ;D

                            Cheers - boingk

                              Lindsay the only pictures are in the first link I posted.

                              They show the first set of holes I drilled.

                              Eventually I decided removing the whole bottom vent was less obstuctive to input airflow.
