"I'm not even using a shop vac -- just a regular old vacuum cleaner. There were three mods I had to make to the Dust Deputy to get it to work as an effective winnower. First, you have to make some kind of provision to get airflow…"
"Classifying after cracking and before winnowing is a great step to increase the efficiency of the winnowing process. I have done it manually as making (or buying) the screens is significantly less expensive than buying a vibratory screener from…"
"For those who have used a dust deputy for winnowing, what horse power shop van did you use? I am trying to set up now but am not getting enough upward airflow in my vortex to suck the husks upward into the second bucket. Thanks for your…"
"Thanks David! That's very helpful, I've been looking into modifying a regular meat grinder, and it wasn't going to be easy. Would you be willing to share the battery-powered rotisserie drive and drive adaptor you find to work?
"On the KitchenAid food grinder the auger goes through the bearing at the back end and floats free at the exit end, so it runs just fine without the plates in place.
I did find that the KitchenAid mixer, even on low speed, is faster than my winnower…"
Great winnow feeder! I had been thinking about using a meat grinder for this purpose but have not been able to get around modifying the thick metal screen that holds the auger in place on all meat grinders. If this were kept in place the…"
"Yes -but you don't necessarily need to make all the passes at the same time on the same day.
You can focus on the "hearts" fraction in a single pass, knowing that you're not getting the greatest yield. Collect the tails fraction…"
As with everything, your mileage may vary and it all depends on your interest in tinkering and your skill levels. Even with the winnower off Chocolate Alchemy the yield will vary based on many factors - the cracker is just one of them…"
"Is it efficient enough to get a crankendstien mill and the shop vac winnower off of chocolate alchemy? Or are these newer ideas going to be much more efficient. I am about to put a winnower together for my first time. :)"
Cracking on a small scale is a challenge most craft chocolate makers face.
Most people start with a Crankandstein. This machine, too has a reputation for over cracking, but it's one of the best solutions out there that you can…"
"Thanks Clay.... Rochelle here, I'm just trying to find a better solution for cracking my beans. I have this beautiful old hand mincers and thought about placing a motor on it but it breaks the beans up just a little too much sadly."
"I agree with Clay's numbers. Measured a different way, if I start with 10kg of roasted beans, I estimate that somewhere around 8.8kg is the best ideal-case recovery (that assumes 88% nibs, 12% husk and germ). Starting with 10kg I usually…"
In Dave's single-stage vortex winnower, the majority of the fines will end up in the second bucket and not end up in the shop vac. But I don't think that's the question you are asking.
The percentage of dust (or fines) will…"
