The objective of commercial rice milling is to reduce mechanical stresses and heat buildup in the grain, thereby minimizing grain breakage and producing uniformly polished grain. Compared to villagelevel systems, the commercial milling system is a more sophisticated system configured to maximize the process of producing wellmilled, whole grains.

16. MILLING SYSTEMS A rice milling system can be a simple one or two step process, or a multi stage process. In a one step milling process, husk and bran removal are done 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 ...
