    Roasting not just browning

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    guys have not long been roasting via popper as heat gun blew up and had a popper in cupboad so thought I might give it a shot.

    My question is around roasting my coffee rather than just browning it. Wth the heat gun u could turn down the heat to give it time to roast bringing out sweeter dlavours etc. But with popper either on or off. How can I slowly roast my coffee?? Thought cover chimney with all floil and switch off popper and switch on-repeat???

    You could try directing a fan across the top of the popper after FC which may suck out some of the heat (venturi effect) to slightly extend the time into SC.

    ...or you could buy another HG *:-/

    TG I think it is a black n decker.
    What I meant with the foil is when I switch off the popper put foil over the chimney for 30 seconds or so then switch on popper again and uncover, keep doing until FC then SC.

    Thoughts its kinda like a mini oven. :-?

    Hi mC,

    Apparently with poppers it is widely recommended NOT to cycle them without thorough cooling between uses.
    In the poppers that I have opened including the B+D, the circuit board and motor are close to the heat source. I concluded that repeated uses may allow heat to infiltrate to the motor and cook it when its running (probably what TG was getting at).
    To cool the popper contents you could increase the air flow (may be difficut) or spray a little fine spray of water on beans (maybe using a $2 spray bottle) I have not tried this but apparently commercial roasters have or may resorted to this method.
    Like FA to fix or replace heat gun would be my preferred approach.

    Do a roast and tell us the times you achieve 1st and 2nd crack.
    From there you can decide how much modification you need.

    Spot-on Lindsay... 8-)

    Eventually the (plastic) fan either softens around the hub and rips the centre out or the blades harden and become brittle enough to shatter. Either scenario spells doom for the popper though.... :(

    TG has some great tips on how to get the best out of a popper and his contributions in this thread (and many others)... http://coffeesnobs.com.au/YaBB.pl?num=1174699442 is worth your taking the time to read.... ;)

    All the best :)

    TG roaster almost 700g this week on the popper FC is around 3:25 and SC around 4:50 been roasting El Salvador green beans.

    time wise how does that sound. My first roast was FC 3:40 and SC 5:55 but was dark and tasted a little burnt.
    Roasts now dont taste too bad, but know the slower the roast the sweeter the taste. So wondered if you could slow down the popper/switch off and on. But also did think about burning out the motor- hence asking about it.

    Typical popper.

    I have a Crazy Popper.
    I added extra holes underneath to let in more cool air and took the top half of the body off to let out more heat.

    See if you can do similar to yours.
    Get more cool air in and drill some holes in the body to let the trapped heat out.
