What is the process of separating husk and bran?

The process of separating husk and bran involves several steps. First, the harvested grain, typically rice, undergoes a process called threshing, where the husk is loosened from the grain. This can be done manually or with the help of machines. After threshing, the grain is then subjected to a process known as winnowing. During winnowing, the grain is tossed in the air using a tray or a machine. The lighter husk gets carried away by the wind, while the heavier grain falls back onto the tray. Next, the grain is sent through a machine called a huller, which further removes the remaining husk from the grain. Finally, the grain is passed through a rice mill or grinding machine where the bran, a layer covering the rice grain, is separated from the rice kernel. This process involves grinding the grain and sifting it through screens of varying sizes to separate the bran from the rice. The resulting end products are husk-free grain and separated bran, ready to be packaged and used. Overall, through a combination of manual and mechanical processes, the separation of husk and bran is achieved, providing clean and refined grains for consumption.
