Extraction Rate What is the Extraction Rate? Extraction rate (ER) is the amount of white flour that is extracted from a given weight of clean and conditioned wheat. It’s expressed as a percentage of the wheat entering the first break rolls in a roller milling system. Aside from size reduction and standardization, [...]
Clear Flour What is Clear Flour? Clear flour is what’s leftover when the high quality white patent flour is extracted from wheat. Despite its name, clear flour is darker in color, as well as coarser and stronger tasting than patent flour. Because of its grayish color, it finds use in whole grain [...]
Milling Also known as Grinding What is milling? Milling is a unit operation that transforms solid particles into smaller ones by applying forces such as shear, compression, friction, collision or impact. Milling processes can be used for making flour or for extracting gluten and starch (wet milling) from grains and cereals. In [...]
Pin Milling What is Pin Milling? Pin milling is a size-reduction technology often used as an auxiliary grinding mechanism in flour mills and analytical laboratories. Pin mills use metal disks fitted with pins to efficiently and quickly break up materials.1 Compared to roller mills, pin mills offer the milling industry a means [...]
Roller Milling Also known as flour milling What is roller milling? Roller milling is one of many methods used to produce flour. It is a process used to separate the anatomical parts of grain kernels—like the bran, aleurone layers, germ and endosperm—and grind them down into fine flour particles. The flour is [...]
Wheat Kernel What is the wheat kernel? The wheat kernel, or wheat berry, is the grain portion of the wheat plant and the source of flour. It consists of three main parts—the endosperm, bran and germ—which are usually separated for different flours and uses. There are over 30,000 wheat varieties, the most [...]
