Milling Bran with the Mikro Pulverizer® Hammer & Screen Mill

Milling Bran with the Mikro Pulverizer® Hammer & Screen Mill

 

Bran is the hard outer layer of various grains. Along with the germ, it is an integral part of whole grains. It is produced separately as a byproduct of milling in the production of refined grains. When the bran is removed from grains, the grain loses a portion of its nutritional value. Bran is present in all cereal grains, including rice, corn, wheat and oats. Bran is particularly rich in dietary fiber and essential fatty acids. Bran also contains significant quantities of starch, protein, vitamins and dietary minerals.

Because of Bran’s significant nutritional benefits, it is increasingly desirable to add bran back into flour used for the production of bakery products. By adding bran to various white breads and other bakery products, its nutritional value can be significantly improved, providing additional dietary fiber and protein to consumable bakery products.

In order to add bran to existing products the particle size of bran must be reduced to the same particle size as the flour. Depending on the flour type and end use, this means grinding the bran down to between 180 and 212 microns. This particle size is required to achieve the same texture and therefore the same sensation (mouth feel) when consumed. Bran is very hard to mill, and to achieve the appropriate particle size a Mikro Pulverizer® Hammer & Screen Mill  can be used to achieve the required grind.
