Title: Popcorn Popper Roasters
Post by: craigbooker on October 16, 2012, 04:42:01 PM
I couldn't find any threads on popcorn popper roasters.  So here we go.  I am looking to get started roasting.  I need something inexpensive with little modifications.

Thrift stores are a good place to start looking.

I noticed I your other post you said you wanted a cheaper alternative to buying roasted coffee:

I must warn you, home roasting may not be the cheaper way to enjoy coffee. It can be a slippery slope. I could buy all my drinks at coffee houses or have beans overnighted from my favorite roaster and I would be money ahead.  I am not trying to deter you from this great hobby/addiction, I am just warning you of the dangers.   For me, though, it has always been about producing the best possible cup.

I am not saying that it can not be done on the cheap. I am just warning you of the alure.

Check out your local Tuesday Morning store - last time I was in the one near my house they had a Westbend Poppery clone for ~$15. For info on using it check out this page (http://www.sweetmarias.com/airpop/airpopmethod.php).

Here are some pics of how I set mine up using a tin of salmon as a chimney (the fried salmon patties were good).

And as the yakker mentioned, it's a slippery slope you going down. Watch out or upgraditus will hit you, hard!

It reminders me a little bit of when I lived in Seattle and did a lot of spear fishing. Friends would come over to our house and say, "It must be great to have a freezer full of free fish, shrimps, and crab." My answer was always the same, "Free, this is the most expensive fish you will ever eat in your lifetime."

That being said, I would buy a popcorn popper, some reasonably priced beans, and go nuts. I got sucked in but I also do not regret it for a minute.

I'm copying a post by Eric in that other thread because it bears repeating;

Quote
One suggestion I always have it to buy five or ten pounds of the same bean. Try to fight the temptation of roasting a bunch of different beans at first. I learned a lot more roasting the same bean over and over at first. I would also look for an inexpensive, not low quality, bean to start. When I started, I under and over roasted countess batches of Kona and JBM.  You get pretty dejected when you start tossing $20/pound beans. Other than that,I might start with something you are familiar with the taste of and know you like. If you buy from a local roaster they might sell you some of the greens that you usually buy as coffee.

I'd ask the OP if you're dead-set on a popcorn popper?  While not quite as inexpensive, HG/DB (Heat Gun/Dog Bowl) roasting offers lots of advantages over poppers.  I haven't priced heat guns lately, but would think $50 would get you roasting.  My favorite roaster, as most know, is SC/TO (Stir Crazy/Turbo Oven) and even with using all new parts you can come in around $100.  There are many who started w/ poppers, and a few who still love 'em, but I'd wager not many stay with them.  You may do well to simply bypass that, and put the money toward a roasting method you'll most likely stay with longer.

While most start with poppers there are a few who have used their poppers for several years, like myself.  Yea it can be a chore but I love my weekly ritual which supports my daily habit.  Its way cheaper than my harley. 
Title: Re: Popcorn Popper Roasters
Post by: J.Jirehs Roaster on October 16, 2012, 08:14:38 PM
IMHO consider the StirCrazy/TurboOven as a start and finish.  I do save money over store bought prices because I rarely buy the real pricey stuff and I have learned to roast pretty good with what I have..  I would love to swan dive into the deep end and get a real drum roaster however so the "rabbit hole" is real... the reason I suggest the SC/TO is the air popper roasts enough for a pot or two.. with the SC/TO you can cut your roasting down to around 2 batches a week (if you drink as little as me)..
Title: Re: Popcorn Popper Roasters
Post by: Tex on October 16, 2012, 08:31:27 PM
I began with an air popper, and I still use it when I get a new batch of beans. And I still use my UFO/CO too, because there are beans that just don't do well in my main roaster. But for most of my roasting, I depend on my Sonofresco - it's tough to beat the convenience of it, even given it's inherent flaws.

I second the opinion of learning with just one bean; how else can one learn what roast profiling has to offer? But once you've learned how to hit a stationary target, move over to Sweet Maria's and buy the big sampler. That will open your eyes to the possibilities presented by the beans from the various growing regions. I know that when I got my first sampler, I didn't fully appreciate the differences between a great Central American or a fruit bomb Ethiopian.

Oh, and about the cost? We don't necessarily do this to save money. At least for me, it's all about having truly unique coffee to make my espresso with. Your local roaster may have a few of the world's great coffees to offer, but to make money they buy bags & bags of the same bean - few have the kind of volume that lets them play with the variety of beans we're offered here. So to me it's all about quality, and if I can save a few bucks and still enjoy the world's best, that's even better!

I'm one of those people who have managed to save money roasting my own beans. I'm with J.J.R., a StirCrazy/TurboOven is the cat's meow.  I also run a heat gun / bread machine, too, if I want a bigger batch.
Title: Re: Popcorn Popper Roasters
Post by: John F on October 17, 2012, 06:59:05 AM
The advantage of starting with the air popper is that you learn a lot about roasting.

It gets you very close to the action and you can see, hear, smell what's going on very easily. You can also get some very nice lively roasts out of it for pour over, vac pot, etc.. I never used it for espresso because the acquisition arc had me in other roasters by then.

It's also great for roasting a small sample.

The death of it is batch size.....if somebody is a one cup a day person it night work but it would take a battery of air poppers to feed my consumption. Way too much work.

All in all I think it's a great way to start.

So what type of coffee bean should I start with?  I want to start with one type of bean as suggested.  Something not to pricey.  I like berry flavors.  I use a Aeropress in the inverted method along with a electric kettle for my brewing method.  I have an Encore Baratza grinder - love it!

Have you got a digital thermometer with a type K thermocouple - they're invaluable for roasting. I'd start with a fruity Ethiopian bean, best bang for the buck until you develop some profiling skills.

That's be a good bean to begin with; natural prrocessed beans do well in a UFO/CO roaster.

Depends who's doing the distro - sometimes it seems to take forever!

Tex is a real time-saver, and a helpful lad; I don't have to take time to answer.   :-*

An unbiased answer...  this lot of Sidamo is very good, and since it'll keep well in storage, you may want to take 10#, just to bring the per lb. shipping cost down.  But in that regard, you may as well throw 5# of Costa Rica in the box.  Take w/ a grain of salt.

Typically, I can ship the day after an order is placed.  Depending on where you live and the distance from Lake Cheddar, you could be roasting in a few days.

I haven't tried this bean, but some cuppers are notoriously chintzy, and some even quibble about quarter points, so an 87.25 must've really made Peter's taste buds light up?

FWIW: I'm trying to talk my niece into buying 10 lbs or so for her entry into roasting, because a natural Ethiopian is the easiest bean to achieve success with.

We'd better watch out or Tex's niece will not only be showing up our latte art but putting our pooched roasts to shame.  Good to see you getting the next generation involved, Tex.

As for the Sidamo, I think that's the recommendation I gave on the Howdy thread, if I remember correctly.  Sounds like a winner to me.

She's turned into the espresso fanatic lately. I think the main reason she visits us is so she can play with my toys? I told her that if she buys her own greens she can use the Sono, or I'd help her put together a clone of my UFO/CO. Who knows, she may wind up a member here at some point and then we'd have everyone out gunned for sure!

Here's how I put one of my UFO/CO units together. I use silicone tubing to help seal the top and keep it from slipping; a tip I picked up from David Mankin (http://www.greencoffeebuyingclub.com/index.php?topic=5033.msg193690#msg193690).

Title: Re: Popcorn Popper Roasters

The slit silicone tube is pointless; the top can't slip off, only go bit off-center, and in a matter of a half-dozen roasts the roastium build-up on the glass top will keep it from slipping too.

Cleaning the glass helps nothing but being able to see the coffee, nothing to do w/ flavor, and you know it.

I buy this at Ace Hardware - 1/16" x 1 1/2" x 4'

1/16" stock is a lot easier to form into a circle than 1/8" stock, and cheaper.

Folks differ on their approaches, but I get good results from this. Not shown is the foil I put on the bottom of the chute, which I remove at the end of the roast to dump chaff into a colander.

It's a piece of the left-over aluminum bar I used for a riser that I cut & shaped to fit, then pop-riveted in place. I filed it at an angle so the CO top would fit snugly. If I was doing it again I'd make the chute a lot smaller.

The two notches are where I fit the two thermocouples for the data logging digital thermometer I use.

Form the strip so it sits on the stir popper, then cut it to length. I'd begin with an overlapping joint; no chaff chute (chaff can be easily vacuumed up after the roast). You can always get as creative as you like after you've been roasting a while.

The video shows how I place the thermocouple so I can monitor the bean mass temps.

Which corn popper did you buy? There are modifications that need to be done for each of them.

This will (again) make me sound like a pompous ass (I'm happy to endure that title to help a n00b create their roaster), but look at the spacer/chaff ejector I use;

https://sites.google.com/site/peter4jc/thespacer,openedandclosed2 (https://sites.google.com/site/peter4jc/thespacer,openedandclosed2)

It's simplicity in action; no pop rivets needed, can be opened or closed to release chaff or modulate heat, and just flat works.

Tex is absolutely correct, that the 1/16" thick aluminum is the way to go.  1.5" high is good too.

Sorry for the bum link -- mine's 1/16, too. I patterned mine off of Peter's and it works great. The only thing I did differently was to drill a hole instead of cutting a slot for the temp probe (which I don't use much any more).  If you drill holes and use screws, don't torque them - only tighten them very lightly as the plastic will break.

I like the simplicity of Peter's design, but I burned my fingers a few times and decided it was for someone more nimble than me - thus my fixed chaff chute.

And I like David Mankin's use of the plate-holder springs to hold the riser in place - it makes dumping the very hot roasted beans into the cooling tray a lot easier.

I use a pair of welding gauntlets (http://www.harborfreight.com/3-pair-14-inch-split-cowhide-welding-gloves-488.html) that I picked up at Harbor Freight. They come in handy when BBQing too.

I use a router speed control (http://www.harborfreight.com/router-speed-control-43060.html) to manage temps - that & a good thermometer gives me pretty tight temp control.

The slit silicone tube is pointless; the top can't slip off, only go bit off-center, and in a matter of a half-dozen roasts the roastium build-up on the glass top will keep it from slipping too.

I like the silicone tube a lot.  It softens the contacts.  Yup....it comes off and has to be put back on.  It's worth it.  Peter has this one wrong.

Why is 'softens the contacts' important?  Are you concerned about breaking the glass?  That's silly.

Spending money on the silicone, spending time installing it, spending time putting it back on, all when it's unneeded...  that's worth it?  If you're going to add cost/complexity to any project it has to have added some value to the project.  If you simply like the silicone tube, I would not fault you for using it.  My post was directed at someone giving advice to a person new to roasting and trying to keep him from thinking the added cost/complexity of the silicone tube had any real benefit, which it does not.

I may concede part of the discussion, IF a person is using the UFO for the bottom, as they're smaller in diameter to the Stir Crazy.

The slit silicone tube is pointless; the top can't slip off, only go bit off-center, and in a matter of a half-dozen roasts the roastium build-up on the glass top will keep it from slipping too.


I like the silicone tube a lot.  It softens the contacts.  Yup....it comes off and has to be put back on.  It's worth it.  Peter has this one wrong.


I could've told you not to rattle Peter's chains, but I thought you could use the object lesson. ;D

No, no; we never say Peter is wrong - that just fans the flames!

I put dabs of hi-temp silicone in the tube to keep it in place;

I don't like the idea of using tape to keep the riser in place because the glue & cloth will impart a flavor to the beans. On my 1st one, with a Stir Crazy that has a raised lip around the outside edge, I used pop rivets to keep the riser put. The UFO has no ridge, so I'm going to od something like David Mankin suggested; maybe a plate holder spring?

Thank you Tex for adding clarification to the matter.  It's a lesson we should all seek to follow.   ;)


Again, my intention was not to tell Susan (or anyone else) how they should build a roaster, but to intercept the suggestion to a newb that the tubing serves any worthwhile purpose.  Now the newb has the decision to make, and however he does is fine too, but at least he'll know going into it there are two sides to every silicone tube.

But there is adhesive that's not rated for the temps of a roaster. And I have seen folks who've used duct tape on the roasters.

Tex is a real time-saver, and a helpful lad; I don't have to take time to answer.   :-*

An unbiased answer...  this lot of Sidamo is very good, and since it'll keep well in storage, you may want to take 10#, just to bring the per lb. shipping cost down.  But in that regard, you may as well throw 5# of Costa Rica in the box.  Take w/ a grain of salt.

Typically, I can ship the day after an order is placed.  Depending on where you live and the distance from Lake Cheddar, you could be roasting in a few days.

I haven't tried this bean, but some cuppers are notoriously chintzy, and some even quibble about quarter points, so an 87.25 must've really made Peter's taste buds light up?

FWIW: I'm trying to talk my niece into buying 10 lbs or so for her entry into roasting, because a natural Ethiopian is the easiest bean to achieve success with.

 Maybe it's just me but I find natural Ethiopians possibly the trickiest of all to achieve success with. Totally different roasting profile than anything else. I find it hard to ever screw up a Oaxacan Pluma or El Salvador bourbon

As usual, I have something to say about something that came up a few days ago.   As you know, my UFO/TO no longer resides here with me but has been relocated to Hawaii.  So, this morning I am passing on to my friend there your suggestions that neither the silicone tubing nor the foil tape are necessary.  He just may find that those items are more trouble than they are worth, and I am certainly going to let him know that several voices have indicated that they can be discarded without ill effect....

Just sayin....

Title: Re: Popcorn Popper Roasters
Post by: craigbooker on October 27, 2012, 02:02:00 PM
I had some issues with power.  Seemed having the TO and SC plugged into the same power strip was setting off the power strip.  So my power kept fluctuating.  This made things a wee bit difficult to keep the temp consistant.  This is what probably caused the somewhat uneven roast.
Title: Re: Popcorn Popper Roasters
Post by: grinderz on October 27, 2012, 02:06:38 PM
Most of those power strips are rated for 1500 watts and you're over that with both of those plugged in together.

What kind of beans and how many ounces of greens did you use? You can mod the stirring wire to get a little better agitation, but most folks have best results with a bit under a pound of greens. 14 ounces seems optimal to me.
Title: Re: Popcorn Popper Roasters
Post by: craigbooker on October 27, 2012, 02:08:38 PM
What can I do about the power strip?  Are there alternatives?  What do you suggest?
Title: Re: Popcorn Popper Roasters
Post by: grinderz on October 27, 2012, 02:17:08 PM
I would try not to use any extension cords at all as they will lower the voltage somewhat. If you don't have a two outlets available, I'd use something like this:

(http://ep.yimg.com/ca/I/cinemasupplies_2234_320857746)

The other consideration is that if you have other things running on the same breaker switch circuit, that will lower the juices as well. I once had a roast that was taking way too long to progress, and came inside and found that the wife had plugged a space heater in to an outlet on the same circuit I was roasting on.
Title: Re: Popcorn Popper Roasters
Post by: peter on October 27, 2012, 02:21:16 PM
Looks like some kind of stinkin' Sidamo by the looks of it.  Dry-processed beans will be inherently uneven, so they look like they should.

If you haven't put the SC heater on a switch, I'd suggest that.  You don't need that heater 99% of the time, and having a thermostat on both top and bottom can drive you crazy.


I use three different circuits, one each for my two TO's and the third for the two SC's.

It's important to get the beans into your cooling setup as quickly as possible. That's where the welders gauntlets come in handy - I can grab the hot roaster and dump the beans into the sieve I have on top of a fan.

At FC+ (454°F) the beans will continue to cook until they're forced to cool down.

Maybe not the way you use it, but I want to get the roasted beans cooled as fast as possible. To do that I pick up the SC unit and dump the beans into the sieve that sits on the fan - and the SC can be pretty hot after roasting coffee to 454°F.

You might say I'd rather be safe than sorry?

That cat reminds me of the wife lol,  I only use a pair of leather gloves, never burnt my self yet. The only thing is move quickly and have your cooling system next to the SC/TO, works perfect for me. been doing it this way over 3 years and roasted hundreds a pounds 12 to 16 oz at a time, it has never cease to amaze me of how tough these SC/TOs are, I have three of them and never had one fail on me. Won't be roasting this way much longer, my new roaster should be hear early next week, the ability to do 5 lbs at a time will be huge for me.

Colanders work OK, but any unused holes up the sides will dramatically slow down the cooling.  You want something where the coffee is covering all the holes.

Like this.

Get two if you are going to cool by pouring back and forth.
Get one good sized one if you have a fan you can turn horizontally and put the colander on top.

Here's an old video I made a while back.  If you fast forward to about 4:40, you'll see my bean cooling technique - a box fan and a mesh box.  Both from Target, and both cheap!  SUPER efficient.  Notice I can go from roaster temp to hand held in about a minute.

Title: Re: Popcorn Popper Roasters
Post by: Tex on November 01, 2012, 04:28:58 PM
My cooling rig is a mesh colander on a 5-gallon bucket with the end cut out, sitting atop a fan. It could be a bit wider so dumping the beans into it would be easier, but it cools 454°F beans to room temp in a minutes or so.

The main things is you want to stop the roasting process at a precise temp, then cool the beans as quickly as possible.
