Topic: DAK BM agitator problems (11 msgs / 226 lines)
1) From: Bill
Hey all.  Ok, so I found a BM at a thrift store, an older DAK "auto bakery"
that looks like R2D2.  I checked the archives and I've seen that a couple
folks here have used the DAK.
Ok, so here's the problem.  The agitator kept getting beans stuck under it
and popping loose.  I was roasting a Mandheling, which may be flatter...
I roasted a Kenyan peaberry and a Colombian decaf first.  No problem with
the agitator.  But the agitator popped up probably 4 times as I tried to
troubleshoot...
Any suggestions on what I can do to make the DAK work for the flatter bean?
 I hope someone has a suggestion.
Thanks
bill

2) From: Vicki Smith
The only think I know folks have done is to shave/cut enough off the 
bottom edge of the agitator so that it clears the beans. I guess that 
all the action in the bread pan keeps the beans moving enough even if 
the stirring part is passing over the bottom in this way.
I'm assuming you don't have a big investment in the machine, so it can't 
hurt to try.

Bill,
      I am not sure I am thinking about the DAK, I bot and  
disassembled five different bread machines at the same time, but one  
of them would catch beans between the end of the agitator and the side  
of the squarish container.  I cut about a quarter of an inch of the  
end and it worked fine.

5) From: Bill
the flatness of the sumatrans is slipping under the agitator.  This is an
older model with a hole in the bottom of the pan (gotta dump the entire
machine because beans come out of the bottom).  anyway, the flat beans are
slipping under the agitator arm into the hole, and then the agitator as it
spins pops off of the 'agitator driver' the circular connector to the motor
that spins it...
I know that RayO had a DAK.  Hoping he chimes in on this thread.
Appreciate the help Jim and Vicki.

6) From: Bob
I took a large steel washer & ground out the center until it 
fits over the shaft. It acts as a barrier and I only have one or 
two small beans get past it during a roast. I have to watch for 
it when I dump to cool, but it works like a champ.
Also converted my stir crazy to a cooler, instead of the 
convection oven, it now has a box fan on top. Cools quickly and 
evenly.

7) From: Bill
Alright, I appreciate the advice on the mod, Bob.  Sounds like that would
work great.  Can I make sure that I have it correct: you place the washer
under the agitator, to buffer between the bottom of the BM and the agitator
arm?  I'm pretty sure that's what you're saying.
Thanks for the suggestion.

"...RayO had a DAK."
I did, I did, indeed. Fall down, go Bang on the last dough it kneaded, so
the picture window dome top is wiped out.
I had the hope of reflashing the firmware to turn the whole thing into a
coffee roaster. Until it walked off the counter and Keerash!
The duct is easy to modify for the installation of a finned air heater,
directed down on the beans, and a flap can be added to the agitator arm to
minimize the clearances that catch and mash beans.
The biggest thing was going to be the cyclone to vacuum the roasted beans
out of the pan after the roast. Dumping the whole thing over to pour out the
beans is an obstacle, so I'll still go with the cyclone and a flat spiral
agitator.
Meanwhile, like Vicki's Sunbeam, the Oster is my ROster.
Cheers, Mabuhay -RayO, aka Opa!

?i had a similar problem with my r2d2 machine. i found the beans getting caught between the end of the aggitator and the wall of the container. i took a hammer and bent out the 4 indents at the bottom only and that fixed it. i took a hammer and swung the hammer with the basket and hit my garage floor this pushed out the indent...hope this helps. i'm 40+ roast in and no problems yet.
