photo 162 Well, weíre finally ready to mill some wheat. Hereís the milling floor. As I mentioned before the trick is to remove the endosperm (where the flour is located) from the kernel. The wheat enters this room from the floor above and goes to the mill in the back left of the room. Thatís called the first break. Click here to see inside the mill. The whole milling process can be explained as grinding and sifting, grinding and sifting. The wheat will eventually go through every mill in this room before we have flour!
photo 163 On the left is the tempered wheat and on the right is the crushed wheat that has gone through the first break mill. There looks like thereís a lot of flour, but thereís still a lot of the endosperm still attached to the bran (the outer layers of the kernel). So, it will be sifted and milled several times.
photo 164 The first break material is blown to the floor above into a sifter. This is the sifter room. The material is sized through screens and the large material is sent back downstairs to another mill and the flour that is removed sent another direction. Remember grinding and sifting, grinding and sifting. As you move from left to right in these sifters the flour becomes purer. Have you ever heard of enriched flour or enriched bread? Well, that long apparatus in the right foreground of the picture is where minerals and vitamins are added to the flour just before it is bagged.
photo 165 This machine is called a purifier. It separates the bran from the finer flour particles using air and cloth screens. Weíve almost got pure flour now. After this process the vitamins and minerals are added before bagging. Youíve got a question, donít you? How many pounds of flour will a bushel of wheat produce? Generally, a 60 pound bushel of wheat will produce about 45 pounds of flour and 15 pounds of millfeed. Millfeed includes the bran, shorts, and germ that can be feed to livestock.

If you are little confused about the milling process donít worry, just remember all the flour doesnít come out of the kernel at once. Each time wheat goes through a break (Thatís miller talk for passing through a roller mill.) a little more flour is extracted from the kernel until they canít get any more flour. Click here to see a short diagram of how wheat moves through the milling process.

photo 166 We have flour now and it has to be shipped out. The flour is measured by weight into bags. When a bag is full, the flour flow stops and it is sown shut.
photo 167 Just to let you know how far weíve come in the milling process, the bag on the left is the wheat that came through the first break or rollers. The top bag on the right is the bran that will be feed to livestock and the finished product, flour is in the bottom bag on the right.
