Hey, Has anyone else who roasts with a popcorn popper tried making it adjustable to better control the roasts? I have been roasting for a few months with my popper with mixed results. I brought in some of my roasted beans to the coffee roaster who i have bought green ones from and he said he thought the roasts were going too quickly, and the outsides of the beans were far more roasted than the inside sections. He suggested i try to increase the length of my roasts. I experimented some with fans blowing on the roaster and taking the lid off the roaster, but the beans were still roasting quite quickly. Most recently i took a dimmer switch, normally used for a lighting fixture, and hooked the popper up to it. I have only tried it once but it seemed to work great! Has anybody else altered their poppers like this, or have any other good suggestions for controlling the roast in a popper? Thanks, Will Mehls Cheap talk? Check out Yahoo!

Will.. That is the biggest problem with a popper - I roasted with a popper for 2 years. People around the list tend to recommend putting a couple of extension chords between the plugin and the popper -- that will slow down your roast a little. For me, it still wasn't enough. I tended to dump the beans out of the popper at 1 minute intervals (which had the effect of cooling them a little). I'd roast until I started first crack, then dump the beans out for 30 seconds, roast for 60, dump out for 30, etc. until the roast reached where I wanted it....that usually slowed the roast down to about 10 mintues (or a little less). You'll want to be careful with the dimmer switch - most dimmer switches aren't rated for the kind of wattage that most poppers draw. You can get industrial ones, but then you might as well purchase a variac (the industrial dimmers are REALLY expensive). Hope that helps.

I spit wired my Poppery I and put a variac on the heater coil. I can totally control the amount of heat going into the beans. I can stretch out a roast to last as long as I want now. Some people put a dimmer controller on the fan power to be able to control it too. I just let the fan run full blast as soon as I plug it in. My roasts are much better now. I guess the next step is the Stir Crazy and Turbo Oven combo. I have the oven on the way now and have already modified the stir crazy by disconnecting the heating element. Now I will be able to do 1 pound batches instead of 265 grams. Wooo hooo Roasting Realtor
I didn't get great results with a popper either, but I wasn't about to modify it. Didn't seem worth it to me when I can use a heat gun (which I already owned) and get better roasts. Very little investment, other than a brand new dog bowl! Sheila Tim TenClay wrote: <Snip>
can you hear first and second crack over the heat gun? i don't know how loud it is but i imagine that it's like a hairdryer. John Nanavati Plainfield, New Jersey
Yes you can hear the first and second crack, the heat gun isn't that bad, Well let me say my HG isn't. (Wagner Digital HT3500 1500 watts) i can hear everything those little beans are doing. scjgb3
You can definitely hear the cracks. I was amazed at how different it sounded from what I heard using my IR2. Part of it might be the quantity. I roast using a heat gun/bread machine. vicki john nanavati wrote: <Snip>

Thanks for the feedback. I'm starting to think that I may go the way of HG/DB. It sounds like you have much more control over the roast than an uncustomized popper. I don't mind messing around but am not seeing the Poppery as worth the time investment - small batch. I use a bread machine and am able to hear the cracks over top of it <Snip> I am, however, interested in the Bread Machine approach and will probably followup with you later about that. I have an old DAK bread machine that I haven't used for several years and would be very interested in customizing it. Happy day.
John - go to a Thrift store and get a coffee roaster. Popper. You could lose $5 trying and failing - but you can cover that gamble! Brett On 11/29/06, john nanavati wrote: <Snip> -- Cheers, Bretthttp://homeroast.freeservers.com
FWIW, I use an old Sunbeam and haven't had to do any customization at all. I use it on the dough cycle, which runs for 22 minutes on my machine. If you are going to do a really big batch, you can stop the bread machines I have part way through, for just a few seconds, and then restart it, giving you a whole long time for roasting. On my machine, you can't start it immediately if it gets to the end of the cycle. If I am roasting 1.5 pounds or less, I just run it straight through and have time to spare. I have tried the stopping and starting because I wanted to figure out if it could be done. I've also roasted in the bread machines of various of my friends. All of the machines worked just fine on the dough cycle, without modification. vicki john nanavati wrote: I am, however, interested in the Bread Machine approach and will probably <Snip>

Vicki, just to be clear, if I am not mistaken, you use the bread machine only for stirring, right? And use a heat gun for heat? Thanks, Brian On 11/29/06, Vicki Smith wrote: <Snip>

I have a report and some pictures of my first bread machine roast on my weblog. See:http://taming.motime.com/post/597194At this point, the main thing I do differently is that I roast more at once--usually a pound, sometimes 1.5 pounds, and I now use the heat gun on high until first crack gets really going, but then back it off to the lower setting for a bit, before finishing it up with a return to the higher temperature. I'm sure other, more experienced folks can tell you more. vicki Julie Tieszen wrote: <Snip>

i've been popping for a couple months. got one on ebay for about 9. i thought that it was a safe investment to try something new. i've been enjoying the results but want more control - same thing with my marriage ;- ) i enjoy noodling around but am intimidated by cutting and splicing wires. i really love scjgb3's suggestion about opening the airflow -easy and low tech. short of rewiring for a dimmer switch or a variac, i don't see a way with a popper that i can control the speed of the roast. this is what attracts me to the hg/dg solution. John Nanavati Plainfield, New Jersey
<Snip> I've heavily modified my Popcorn Pumper. I control the fan with a dimmer/transformer setup, greatly increased the throughput of air by enlarging openings and drilling new air holes, and = I added a PID for temperature limiting purposes. All of it is built into = the base of the popper, so I have just one piece to deal with, rather than dealing with a separate power supply. This allows several alternatives: I can do extra-large loads: I set the air temperature low enough so = that it will not go beyond the drying stage until the beans are lofting. Once there, I adjust the PID to finish the roast. I can do tiny loads: I can turn down the fan, so that the temperature will get high enough, even with a small load. I can control the length of any part of the roast by adjusting the PID. I can specify the exact air temperature at all times. So far, so good. I'm having fun with it.

<Snip> I use the dimmer only to adjust fan speed, so the standard 600 watt = model is sufficient. I control the heating coil using a PID, which is, in = essence, a fancy electronic thermostat. The two work very well in tandem. I can use the fan control to adjust = the airflow without it affecting the temperature. Under normal = circumstances, poppers go down in temp near the end of the roast. This is because the beans become less dense, and the airflow increases. Before I installed = the PID,I used to just turn down the fan to keep a steady, or rising, temperature. Now I do the same thing, but I have precise control over = the temperature independent of fan setting.

John, which DAK do you have? My oldies are like round silos with hinged dom= e glass tops. The loaf pans are cylindrical. Not hot enough at 350° bread baking temperature to roast coffee barefoot.

On 11/30/06, Michael Rasmussen wrote: <Snip> It is an electronic process controller set up to control temperature. P = Proportoinal I = Integral D = Deriviative Which are 3 modes of control logic used in varying degrees to control the process to the desired setpoint. Proportional control sends more correcting output signal in proportion to the "error" measured against the setpoint. Proportional always leaves a little error by itself. Integral is time related - longer time in error condition results in more signal to correct. Integral is used to line out the remaining error from proprtional mode. Derivative is a mode frequently causing instability - it sends more signal to correct if the error is moving quickly away from the setpoint. For temperature control, you would need mostly Proportional mode, a little Integral mode and probably NO Derivative mode. Safe Journeys and Sweet Music Justin Marquez (CYPRESS, TX)
<Snip> It stands for proportional-integral-derivative. Does that help? :) <Snip> Like I said, it is a fancy electronic thermostat. It uses various algorithms to try to keep the temperature steady. Its input is a thermocouple, and its output attaches to a solid-state (or mechanical) relay, which turns the heating element on and off. I got mine on eBay, cheap. All I was looking for was a digital = temperature readout for my thermocouple, but at the price I saw, I went for the PID. = Of course, that necessitated that I buy a solid-state relay, wire, = connectors and a couple of terminal blocks, and resulted in my dining room table becoming a mad scientist's lair for a couple of weeks while I played = with my Dremel tool and soldering iron, but that was par for the course. While = I had the popper apart, I experimented with different heating elements and beancups, which was also fun.
David B. Westebbe wrote: <Snip> so a PID is part of what you need. It is a switch, and you need a bunch of other stuff wired together to have a complete control circuit for the popper. If I'm understanding: An alternative to a PID would be a variac controlling power to the heater coil with a human being watching a thermometer and varying the variac power to change the coil (and flowing air) temp. In this case the watchful eye of the person and the tweaking of the variac substitute for the PID. -- Michael Rasmussen, Portland, Ore, USA Be Appropriate && Follow Your Curiosity http://www.patch.com/words/

With a functional bread machine- "my machine... still works - although, i haven't used it for a while", I first recommend you get some whole kernel hard red winter wheat and make use of your blade grinder. Grind some fine- not flour and substitute it for about 25% of the flour in a normal recipe. I think the hard red winter wheat has a lot of gluten in it and makes for a nice textured loaf.

This has been a great thread. I figured out how to disable my bi- metallic switch, got a precise description of a PID, and a great pointer for bread. I do make bread quite frequently in my breadmaker. I had previously set aside popper roasting because the bi-metallic switch just seemed to kick in at the worst possible time.
