I'm looking for information on building a small scale oat huller.
I have read that heating the oats to 140ºF makes it easier to get the hulls off. Commercial hullers drop the oats onto an impeller that throws them against the wall of a container to remove the hulls. My Dad said that when he was growing up they had an oat huller to make feed for the baby pigs. It has been so long and he was pretty young so he does not remember how it worked.
