separating husk from berry

Cool idea for separating husk from berry

Very cool idea.

But I’m gonna ask.. how important is it to separate them? I see a lot of guys recommending or using rice hulls to help with draining a mash. Seems like you’re just removing something useful that you’re going to go add right back afterwards. Or is there a reason to treat the two separately?

Seems like it's an updated version of a machine designed in 1737!

My understanding is that the hulls of certain grains can add a bitter and/or astringent taste.

Thanks, I had no idea what this process was called.

After a quick glance it seem like you can get a winnowing machine for pretty cheap on alibaba

It's hardly a new concept.
