The flour middlings, or endosperm particles, are more difficult to separate 

 from the bran. Their subsequent reduction to flour between the smooth 

 rolls is not accomplished as easily as when they were produced from 

 harder kernels, owing to their tendency to flatten out or '"flake," and 

 lose their granular character before the reduction is complete. There 

 is in consequence an increased loss of endosperm or floury material in 

 the feeds or by-products. Increasing the length of the milling system 

 aids somewhat in effecting a more complete separation but involves 

 greater expense of operation.
