Today I visited my local maize mill with my friend Flora, and she showed me the next steps in the maize to ufa process.
The maize kernels we're poured into metal buckets and rinsed in water.
Then the kernels were poured into the coarse grinder.
The bran has been detached at this point, but is mixed up with the kernels. Using wide flat winnowing baskets, the maize bran is separated out.
The maize bran is collected in a maize sack, and the remainders of the kernels are stored in a bucket. They are still very coarse at this point, so they need more grinding to make ufa (maize flour). That's where we stopped today though. They are going to bring the maize back for the final grind another time.
A-maiz-ing! (I couldn't resist)
