Rice Or Barley Polishing Machines

Rice Or Barley Polishing Machines

Rice and barley polishing machines are devices used to remove the outer layer or bran from grains of rice or barley, respectively. The purpose of this process is to produce a more refined and polished grain that is visually appealing and has a longer shelf life. The machines work by using friction to rub the grains against each other, causing the outer layer to be scraped off. Rice polishing machines typically consist of a rotating drum that contains abrasive material, such as emery or sandpaper, which rubs against the grains as they pass through. The machine also has a blower that removes the bran and dust that is produced during the polishing process. Barley polishing machines are similar, but often use a different type of abrasive material, such as carborundum, and may have additional features such as water sprays to aid in the polishing process. While the primary purpose of rice and barley polishing machines is to improve the appearance and shelf life of the grains, there are also potential health benefits associated with consuming polished grains. The bran layer of rice and barley contains fiber, vitamins, and minerals, but also contains phytic acid, which can inhibit the absorption of certain nutrients. Polishing the grains removes much of the phytic acid, making the nutrients more bioavailable. In conclusion, rice and barley polishing machines are important tools in the food processing industry for producing visually appealing and longer-lasting grains. While there are potential health benefits associated with consuming polished grains, it is important to note that the polishing process also removes some of the nutrients found in the bran layer.
