parchment removal

Postby Daniel on Tue Feb 01, 2011 3:38 pm

Many samples I receive are in parchment, and I was wondering...

Does anyone have a recommendation other than the tried and true 'rub between your fingers' method of removing parchment ?

Beside being very time consuming, I find that the silverskin isn't sufficently loosened to come off during the roasting process, resulting in chaff covered beans / uneven roasts.

Perhaps somebody knows of a source for a small hand-crank milling device ?

Thanks!
Daniel

What about wrapping the sample in a clean kitchen towel and grinding the beans together (like one might do to remove skins from hazelnuts). This might provide more friction and control while reducing hand fatigue.

A Corona corn/grain mill works pretty well, given two passes through.

Try pulsing it in a food processor with the rubber blade in place.

Old bike tire inner tube...cut a length of two feet or so, tie one end. Fill with parchment coffee, tie the other end and roll it on a hard surface. Untie, winnow and you have clean green coffee.

If you could get a bunch of old bicycle inner tubes sent over from Rwanda... from Bikes to Rwanda... the circle would be complete.

We have received a few samples in parchment, we bought a cheap sifter and created larger holes in the screen at the bottom. It worked pretty well.
