My father in law grows Montana Spring wheat.

I can get as much as I want, straight out of the combine.  He has a grain cleaner, and mill for large batches of flour, but I dont want to spend a week cleaning the mill before I use it.  if I bring a 50# bag of wheat berries home, how do I clean the chaff, dirt, bugs out of my wheat?

I can clean, sort the big pieces from the wheat in small handfulls.

Question, Can I rinse the berries before I mill them? and how should I dry them after that (in the oven?)

anone else have this  "problem"
