Vitamin Blade Mill and Bran Extraction
Hello!
I'm using the Vitamin Dry-Container to mill my wheat berries (usually hard white and red berries) and sift afterwards through a #40 and #60 sieve. If I follow the 60 second at high-power instructions given by Vitamix I still get a good amount of very coarsely ground flour which will not pass through the #40 sieve and the yield would thus be terrible at around 50% of the initial amount. So I'm grinding the berries for another minute totaling 2 minutes.
I DO have the strong suspicion that milling the berries to a fine flour will cause the bran to get equally finer and pass through even the #60 sieve. Is that true? Because I thought sifting is how you would remove bran from the flour but if the bran is the same particle size like the flour then I don't really see how sifting should work to accomplish that. I noticed that the gluten is not as strong when I grind the flour for long. Is this why a burr mill is better?
