    Corretto meltdown - DANGER, DANGER

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Here's a good reason to skip the corretto and buy yourself a decent roaster.

    Another point would probably be to purchase quality heat guns. there is a reason tradies buy Bosch, Dewalt, Makita etc. they are reliable. The price difference is easily balanced out over time. I don't know the brand of gun in the photos, so please take this as a general warning. There are other good brands, I have just mentioned a few. chippy

    It wasn't the brand of gun. He forgot the roast was on and left it for half an hour or so.
    Result - serous flames, smoke and meltdown.

    I disagree, people can and will misuse any device known to man, power saws are dangerous, its easy to damage yourself with one, deep fryers can ignite, cars are death traps, people die in em every day, the list is infinite, we still continue to use these things (most of us take the necessary precautions when doing so) because we find them useful.

    The Corretto is a great low cost roasting setup that produces excellent results, been using one weekly for almost 10 years and never once looked like starting a fire.

    Of course if you have the attention span of a gnat you may want to stay away from em, and cars, and motor bikes, and power tools and kitchen knives, and lawn mowers and skate boards, think you get the picture.

    So not so much the Corrette setup that was dangerous........ rather the user.
    Amazing that he couldn't stand there for the <20 minutes it takes to roast!!

    As Yelta has pointed out....... plenty things out there much more dangerous than an old bread maker and heat gun...

    Yep - I told him to invest $10 in a timer - or use his phone timer. He will.

    The melted gun is a bit of a work of art.

    And as a precaution keep a fire extinguisher and blanket handy as we do in the kitchen, kitchens are dangerous places.

    As a matter of interest Paul you've obviously posted pics, I'm not seeing them.

    Got it sorted, Adblock Plus was doing its work very effectively, all good now.

    If he had a "decent roaster" and forgot about it he'd likely be in just as much trouble, don't blame the roasting set up for user error.

    Looks like an Ozito - Bunnings will replace it, no questions asked

    I find this surprising. I thought heat guns had to have an overtemp cutout. I'm certain my cheap Ryobi has one. Was the exhaust constricted in some way?

    Of course, my RPi controlled corretto program turns of the heat after the roast time is finished and leaves the fan running, so if I forget to check, it will simply cool down.

    Ah yes, electronics and computer programs never fail, soooooo, it's perfectly safe to set her running and pop down to the pub to buy a six pack.

    Corretto meltdown - DANGER, DANGER

    I'd still be suss on the gun - most of my roasts end up 20 minutes plus and I've done 4-5 roasts back to back without ever having the gun even overloading. Not sure what happened there unless the thermal cutout didn't work or the exhaust port for the roaster pointed back at the gun!
    Weird ...

    But still - any roaster unattended is a disaster in the making

    More than likely the HG intakes became blocked with chaff, the reduced airflow caused overheating that the "protection" failed to detect...

    I'm with Matt, never ever come close to this happening so serious neglect on the part of the operator....

    I use the same HG and have had the temperature dial melt off and the black plastic around the output nozzle blister. But that's from heat reflected back to the gun (which incidentally also gets reheated in a potentially disastrous feedback loop).

    But here he's got the gun away from reflected heat. Must have been a decent size flame to melt the feet on the bread machine.

    Forget the timer... NEVER leave a roaster... ANY roaster unattended! As Yelta pointed out, it's less than 20 minutes to invest.

    As long as you don't use a timer as an excuse to shoot through, I find them a handy 2nd line of defense (and also a good way of making sure that I don't miss the Behmor auto shutdown threshold if I'm too busy looking at the beans .

    I don't regret that the KKTO forces you to use the timer :P

    Well, I've been home-roasting now for about 14 years and in all that time, have never found the need to leave the roaster unattended, for any reason. It's always been something that I enjoy doing so never begrudge the time spent doing it...

    Experiencing the changes in the roast as it's progressing is half the fun!

    I agree with all the above - we definitely need to keep an eye on our roasts.

    An action item for me is to move my roaster further from the house. I currently roast outside, but under a pergola. However, IF the roaster started to burn and IF I wasn't standing right there (as I normally do) it is possible that the unattended flames could reach the pergola. Easy fix, as the roaster is on a trolley. Thanks to KBC for raising it.

    I wonder how many of us have one of each of these adjacent to their roaster?

    That's an Ozito heat gun, appears to be the same as the one I use (though mine is rather heavily modified), can't say I've ever had issues, I don't expect it to last as well as a Makita but it does the job.

    Not immediately adjacent but I do have one 5 meters away in the kitchen and another one about 5 meters away in the garage
