    coretto issues

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi, my name is John, I have a welbilt breadmachine and a broken heat gun. I live in the states, florida to be exact. First question is which heat gun to use? This one did not survive 4 roasts. Got it from harbor freight for 10.00 dollars. Second, the rotor stops after 13 minutes, I have to quickly reset it and it takes a good two minutes to start rotating effectively. Can I just jumper out the motor or can I short out the transistor I think is controlling the motor? Also, is there a way to use the breadmachine to provide the heat? It is after all a little oven. Thanks, the first batch was done in by heat sensor that shut off machine, which is now repositioned. The subsequent three were all very nice. I have been using a popper for over two years and this method reaaly is superior for me. Anybody want some popperys here in the states, send me an offer + shipping. I have 4. Thanks in advance, John

    Hi John a lot of CSers bypass the wiring in breadmaker so that it will runs continually.
    I use a Ryobi 2 speed heatgun, Ive done 150 roasts now and its still going strong, I use a small fan to cool down the body of the heatgun and blow the chaff away from gun and bread machine, this helps extend the life of the heatgun as well as chaff clearing.
    Its a great roasting method once you get it all set up properly, get a temperature probe to monitor the bean temperature as well and you will have total control over your roasts.
    Welcome to Coffeesnobs, its a great source of information on all things coffee.....................gm

    Welcome to Coffee Snobs John.

    Good to see youve moved the heat sensor; thats a start.
    As gm said, with a breadmaker that doesnt have a long enough cycle, the trick is to direct wire the motor to run continuously.

    Im no electrician so cant help you with that.
    Assuming Welbilt is the brandname, we dont see those here in Oz that I know of.
    It would be best if you can find a friend over there whos qualified to poke around inside electical equipment.
    Otherwise it can become a lethal misadventure.

    A $10 heatgun will never last long as youve found out.
    Get a name brand one; theyll last much longer and work out cheaper in the long run.

    Once you get it going (Ive finally got one now) youll be glad you did.

    Welcome to CS John

    Good advice from the above posts and I second the fan set up
    It is important that the heat gun draws in cool air through clean slots (no chaff clogging) past the motor as it is the only way the HG cools its armature down
    If you dont do that even an expensive HG will fail

    Re: coretto issues

    Hi there
    Further to all the responses above, using the breadmaker as the over will not generate enough heat through the beans to roast evenly. I would imagine you will find that some of the beans will become scorched due to contact with the bread pan.
    The HG is definietly the way to go, I have a Bosch HG with variable fan speed and temperature and it has been working from just shy of 2 years now and done at least 200 roasts in that time. I too use a fan to keep the gun cool and blow away the chaff. I also use a block of wood to cover half of the bread pan so that i can drop the heat output of the gun, since doing this the gun is never at the top end of the heat it can provide and my roasts are much more even.

    Thanks, The breadmaker was only 9.00 so I may try to fust wire the motor off of a switch, the heat gun will be replaced by name brand one. Have to say this really exceeded my expectations and made some coffee taste good that the hot air popper could not. I may have underestimated the power of slower roasts. Thanks again, John

    Welcome John

    I second everything the others have said and also strongly recommend you consider a heatgun with variable temperature.
    I find adjustment to the heating profile between FC and SC is best achieved with a combination of physically raising the gun and backing off the temp a bit.

    Bosch and the Ryobi seem to be the most preferred brands downunder.
    Good luck

    Re: coretto issues

    Ive been using a Makita HG1100 for a year, only problem I had at the beginning was when I was holding the gun 1-2 inches from the beans and the plastic around the nozzle was starting to melt a little. No problems other than that. I wrap some AC filter material around the gun intake to prevent chaff from getting in there.
    I rewired a Breadman to run continuously, it was not too difficult, need to bypass the circuit board and the capacitor.

    Re: coretto issues

    Does a breadmachine with 2 paddles do a better or worse job? The local thrift has a zojirushi for 5.00. It has 2 paddles. Leaning towards the makita heat gun cause I can find it. Thanks, John

    Does this BM use a horizontal bread-pan as opposed to the more usual vertical ones John? Our BM is a Breville Big Loaf which is a dual paddle job using a horizontal pan and is able to roast up to 1.5Kg loaves of bread. For coffee though, it easily roasts batches of a Kilo but is problematic with batches below 300g (roasts tend to be uneven and the beans get chucked around all over the place).

    My usual batch sizes of 700-800g green (these days), are very easy to do being both predictable and superbly even in colour and texture. So, if the BM youre looking at appears to be in good condition, it may well be worth picking up and using as a dedicated roaster....

    Cheers, :)

    I was guessing it would be similar to yours Mal.

    I had a laugh...

    In fact, its identical.... "The BM by any other name would still roast the same" springs to mind ;D

    Lucky for John then because he can download a manual from the website and he wont need to modify it because it has a "cake" setting that immediately kneads for 25 minutes.

    Re: coretto issues

    I will let you know, as soon as I get off work early enough to get to the thrift store. May have to try calling and have them hold it for me. I am doing a pound in the one I have now. I start it up and after a few minutes I restart the cycle. It goes kind of slow but I dont think I am far enough in to ruin the coffee and it tastes pretty damn good!!! Thanks, will get a temperature probe soon but I bought a shotgun and am short of funds till payday for the advanced expensive stuff. John

    No, I think brokenarrowjbe means he will be employing the shotgun to rectify the sudden shortfall of funds that is preventing him from obtaining a temp probe??? *:o *:)

    Behmor Coffee Roaster
    I used my available money to buy a shotgun. Now the wife has put the purse strings in a tight grip. The local thrift had already sold the breadmachine, so I will have to limp on with the start stop method.

    Locally the heat gun of choice appears to be wagner cause that is what everybody but harbor frieght is selling so I will have to order one of off ebay. The roast is still better than hot air popper, but deadly on cheap heat guns.

    Will keep my eye open for zojirushi bread machine,thanks for all the advice, John
