the crown roller mills company was founded in timaru where it operated the atlas roller flour mills. originally built in 1867 using bricks and oamaru stone and fitted with anderson and mouat's steam flour mill. it was extended in 1890 (the date on the top of the building) by the addition of two additional floors to accomodate new steel roller
the particle size distribution of stone milled and recombined roller milled flour was also studied. considering the above mentioned parameters, we found that there is no compositional difference between a stone milled or a roller milled flour if, in this latter one, the milling streams are all recombined, but the particle size distribution was
modern bakeries rely on industrial mills for their flour. but a small and growing number of bakers, chefs and pasta makers are making their own flour with the age-old method of stone milling.
due to the difference in the grinding process, the stone flour contains a large amount of carotene and dietary fiber, so the stone flour is naturally white and slightly yellowish. while, the roller mill flour appears very white for the using of high-speed and high pressure to take a
