On these hard-wheat patents the bran particle count ranged from 
15 to 72, with an average of 30. The hair count ranged from 2 to 45, 
with an average of 18. The total offal count ranged from 15 to 117, 
with an average of 45. 
PATENT FLOURS MILLED FROM SOFT WHEATS. 
The patent flours milled from soft wheats are more starchy than 
those milled from hard wheats. This starchy character is manifest 
even when the sample of flour is poured out upon a piece of paper. 
The soft-wheat flour will not "flow" like a flour made from hard 
wheat, but is more " powdery " and starchlike rather than granular, 
as in the case of hard-wheat flours. Thirteen patent flours stated to 
have been milled from soft wheats were examined microscopically. 
As in the case of hard-wheat flours, the commercial grades, as indi- 
cated by percentages, varied markedly, and can be regarded only as 
approximate. The percentages ranged from 35 to 90 per cent. 
Some of the flours were bleached, others lightly bleached, and still 
others not bleached at all. Table 17 gives the results of this examina- 
tion.
