    Didnt hear the crack

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I did my first roast last night using a popcorn maker and i didnt hear the first or second crack, my popper does roar a little but i thought the crack would be as loud as popcorn.
    i ended the roast at 22 mins when i thought it smelt done how long should i let the beans sit after roasting i thought about 24 hours so im going to grind and brew tonite
    will let you know how it tastes

    22 minutes in a popper! What size batch were you using? Were the beans moving on their own or did you have to stir? I cant recall popcorn noise too accurately but I can always clearly hear distinct first and second pops in a popper though some beans crack louder than others.

    The last time I used mine (xu1 heat gun died this week mid roast *:( ) it wanted to hit first crack after 2-3 minutes. I have found light shaking to be useful in preventing to rapid a roast but thats not your problem.

    Strongly suspect your popper is not operating in spec. 22 minutes straight at "normal" heat would also be very hard on the machine.

    Hi,

    It might not necessarily be a bad thing. If your bean load is too light then the requisite roasting temps might not be developed. Try increasing your bean load by 10 -20 grams at a time until you achieve a more realistic roast time (less than 15 minutes all up) and distinct periods of first and second crack.

    You might find that you have to tilt your popper over (away from the discharge chute) to prevent unwanted loss of partially roasted beans and to assist bean movement in the popper chamber. Ive got a "Tiffany" Popper and have found that I need to tilt it over about 30 degrees to achieve a satisfactory outcome with a load of about 110 grams of beans.

    Depending on the beans being roasted, the all-up roasting time can vary between about 8 and 12 minutes with my setup so youll probably just have to experiment a bit to get it right. My first Popper used to have all roasts finished in less than 7 minutes and with a couple of batches of Santos beans I had, in less than 5 minutes. It eventually turned out to have a faulty Fan Motor though, didnt push a big enough volume of air through the roasting chamber. Sounds like yours is doing ok though. All the best,

    Dimal.

    Hi,
    I had similar problems before with poppers. Fix the problem by disabling the thermostat. If the popper thermostat is not disabled and ambient temperature is low it just cant get to temperature. This is due to the thermostat cutting out.
    The other problem with poppers is that the fans start to slip after a few batches. Gave up on poppers now. Have been using heatgun and now turbo oven.

    Happy roasting
