A bran separator is a specialized machine commonly used in the food processing industry, particularly in grain milling. Its primary function is to separate the bran layer from milled grains, such as wheat, rice, or oats. This machine employs a combination of airflow, sieving, and gravity to effectively isolate the bran, which is the outermost layer of the grain, from the inner endosperm. By separating the bran, the machine ensures that the final product, typically flour, is free from coarse particles and impurities, resulting in a higher-quality and more refined end product. Bran separators are essential tools in grain processing facilities, helping to optimize the milling process and enhance the quality of flour and other grain-based products.
