rice milling system can be a simple one or two step process, or a multistage process. In a one-step milling process, husk and bran removal are done in one pass and milled or white rice is produced directly out of paddy. In a two-step process, removing husk and removing bran are done separately, and brown rice is produced as an intermediate product.
