How to De-Stem a Grape

If I remember anything from safety training, it's that the de-stemmer is the most dangerous piece of equipment in the winery.  That in itself makes it pretty interesting, so I took some pictures and some video of it in action:

The elevator drops grape clusters into the far end of the machine, and rubber-coated paddles gently beat the crap out of the grapes.  The berries fall through the holes in the steel cylinder and are collected below the machine.  As you can see from this video, you don't want long hair anywhere near the spinning paddles and cylinder.
