Hey, I'm getting some great coffee custom blended and roasted for me through an ex of a friend of a friend.  I'm paying for greens and shipping and getting a blend and roast designed around what I like in a coffee, so kvetching about some chaff that comes along with is kinda out of the questions.  The guy obviously knows what he's doing (the coffee is enormous) but the stuff comes with more chaff than I can ignore.  What's an easy and clean way to get the stuff to go away?

I roast with a BBQ roaster, and cool with a shop vac which sucks air through the hot beans in a colander. Once cool, I take the exhaust tube and blow air in the reverse through the bottom of the colander through the beans; if I'm not careful, I blow beans everywhere, but if I'm cautious, the chaff flies out (@#!$ing everywhere!!! lol).

I hate chaff. I miss the seperating chamber on the Diedrich roaster.

Now, even my girlfriend has noticed the similarities in the way that you and I think, and its starting to scare both of us just a tiny bit.  I was on my way to get new filters and such for the shop vac for just that kind of experiment, and she was the one that sugested that it'd make a huge mess.  Of course, so far, this is the winning method.  Any other contestants?

Roaster: Diedrich IR-12 & an RK Drum

When I was roasting on an RK Drum (somewhat sadly a distant memory, since I've just completed my first month on my IR-12) I had a 2ft square frame with stainless steel mesh affixed to the bottom. McMaster Carr has mesh with 6 holes per sq inch, if I recall correctly - just large enough so that peaberries wouldn't fall through but the chaff would. I had 3" tall legs on the cooling tray and sat it on a table - the whole apparatus on the edge of my patio. I used a standing GE fan (as opposed to a table fan) pointing down onto the tray. I'd dump the beans from my 8# RK Drum into the tray and stir with a long handled wooden spoon....enable the chaff to fly off into my yard both through the mesh on the bottom of the frame, and straight out from the beans when I was stirring. It worked like a charm! Roasting in the rain was tough, but I did it for two years....with a pop-up canopy over the whole operation when needed. I did notice that the grass grew a lot quicker with all that composted chaff collecting on it, given the volume I was roasting.

Princess,

That's a great story.  I am glad you have gone from the RK-Drums to the IR-12.  I envy you terribly!  If you recall I sent you an email a long time ago about roasting and selling.  I have been fortunate to become the supplier to a local coffee shop.  It also helps tremendously that I am the sole roaster in my county.  The nearest roaster is over an hour away and with three thriving local retail coffee shops (two of which have expressed great interest in my coffee) I have a great hold on the market.  Right now I am starting out by selling them beans to serve to customers via brewed coffee/espresso with the option to offer bagged coffee beans by the pound.

Some day I plan to step up to a commercial roaster.  I am currently looking at the Ambex company as well as the beloved Diedrich.  Someday I too will live the dream you have.  Congratulations!

My neighbors can see into my yard; they must think it's hilarious or stupid to see me out there at 9pm, in the cold, roasting coffee in a char broil, and squatting down with a colander in one hand and the vac tube in the other, the eye of a tornado of chaff.

Princess Valiant, nice buy!!! How do you like the Deidrich? Do you find you roast quality/flavor has gone up? How much? I apprenticed on one, and I hope to buy a smaller IR soon. They rock!

TimEggers, ha, you and I are in similar situations! I'm in socal though, so I'm hardly one of a kind like you, but I got a local shop buying my beans, and hope to expand that soon! And I'm sick of the RK; I'd be very happy if it was for my own use, but for a business, I'm not happy with it at all.

Coffeeemergency started the same way. Nice to find others doing the same thing!

my cooling station utilizes  down draft suction.  I cool in a mesh colander and if I stir the beans a bit while cooling the chaff is broken down to a fine powder and sucked through the mesh and out of the colander.  No worry about blowing beans all over the place.

Hey Poison,

Ever use an Ambex?  The price on them is great and I have read many wonderful things about them.  While they are not Diedrich they seem to be a nice alternative.

Thoughts?

Tim, I use an Ambex.  Let me know if you have any questions to help you in your decision. (saw your post on another forum as well).

I hear great things about them, for sure (especially customer service). I roasted a batch on one at CoffeeFest a couple years ago. I personally don't want a digitally controlled unit, so I wouldn't buy one, but I'm not knocking them in the least. The price sure is better.

I'm sold on Deidrich. The one I apprenticed on was the only left handed one they made, and 17 years old. Talk about seasoned! It's simple to use, to repair, to clean, and lasts. The IR series is fuel efficient. And I'm afraid the fact that it's what I learned on plays a huge part in my decision.  I'd consider a Probat, too, but talk about expense.

You might call this guy:

I spoke with him yesterday, and it's kind of strange: he is sort of an agent for people selling roasters and people buying. He hooks them up. I absolutely do not know him or vouch for him, but I'll definately be calling him when I'm ready to plunk down the cashola. And if you read this, Victor, no offense meant. JUst being cautious.
