Does anyone know what the approximate particle size of the cocoa solids after coming through the champian juicer? How about after milling in the Santha? If you don't know can you give an educated guess? I want a filter size to get the cocoa out of the cocoa butter. I've read some stuff about particle size here and other places. But I wonder about what we are getting. I can actually get stainless steel mesh down to 2-3 microns but I doubt that van Houton could. I suspect Giradeli used cotton filters on his press design.
I know there are some real scientists out there. Give me a hint.

Well, the first "hint" is you can't just filter the cocoa solids out. The interstitial forces are too great between the cocoa butter and solids and it simply doesn't flow through a filter (to any degree at least) hence the need and use of a press. To overcome those forces.
For use in a press, a cloth bag would work just fine I suspect (guess). The cocoa solid may start to come through, but will form their own filter bed.
To answer you actual question, I have no clue what size particles the Champion produces.

you can measure particle size with a good digital micrometer dilute your sample 1:1 with vegetable oil place on micrometer surface and dial down. what you get is the size of the largest particle you will still have no idea of the particle size distribution but at least you get an idea

Why does the sample need to be diluted?

so the particles don't clump together. you want to measure individual particles, not aggregates.

Thanks, Sebastian.. I didn't think about that..
Also, can the particles withstand a lot of pressure? I'm worried about applying too much torque on the micrometer.

the problem with a micrometer is, depending on how hard you turn it, you can make it read anything you want it to most of an offset to allow you to 'know' when you've reached a solid particulate. if you turn past that, it'll crush.

Thanks, Sebastian. I guess I'll just have to get the feel for the device.
