RICE MILLING SYSTEM

Milling is a crucial step in post-production of rice. The basic objective of a rice milling system is to remove the husk and the bran layers, and produce an edible, white rice kernel that is sufficiently milled and free of impurities. Depending on the

requirements of the customer, the rice should have a minimum of broken kernels. Most rice varieties are composed of roughly 20% rice hull, 11% bran layers, and 69% starchy endosperm, also referred to as the total milled rice. Total milled rice

contains whole grains or head rice, and brokens. The by-products in rice milling are rice hull, rice germ and bran layers, and fine brokens. Milling is a term that describes the processes of converting paddy into rice. It includes:

· Cleaning: Removing foreign material such as particles of sand, stones, straw, seeds, etc. from the paddy.

· Dehusking and husk separation: Removing the husk from the paddy with a minimum of damage to the grain, and separating the husk from the paddy.

· Paddy separation: Separating dehusked paddy from any remaining paddy grains. Most dehuskers remove about 90% of the husk.

· Bran removal: Removing all or part of the bran layer from the grain to produce polished rice.

· Grading: Separating (or grading) broken from unbroken rice. The brokens are often separated into different sizes.

A 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. In multistage milling, rice will undergo a number of different processing steps.

A commercial rice miller will have following objectives:

· produce edible rice that appeals to the customer- i.e. rice that is sufficiently milled and free of husks, stones, and other non-grain materials

· maximize the total milled rice recovery out of paddy minimize grain breakage

COMMERCIAL RICE MILLING SYSTEMS

Commercial milling systems mill the paddy in stages, and hence are called multi-stage or multi-pass rice mills. 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 village-level systems, the commercial milling system is a more sophisticated system configured to maximize the process of producing well-milled, whole grains. The rice milling facility comes in various configurations, and the milling components vary in design and performance. “Configuration” refers to how the components are sequenced. The flow diagram below shows a modern commercial mill catering to the higher end market (Fig. 8). It has three basic stages, the husking stage, the whitening-polishing stage, and the grading, blending, and packaging stage.

Modern rice milling processes consist of:

· Pre-cleaning - removing all impurities and unfilled grains from the paddy

· Husking - removing the husk from the paddy

· Husk aspiration - separating the husk from the brown rice/unhusked paddy

· Paddy separation - separating the unhusked paddy from the brown rice

· De-stoning - separating small stones from the brown rice

· Whitening - removing all or part of the bran layer and germ from the brown rice

· Polishing - improving the appearance of milled rice by removing remaining ran particles and by polishing the exterior of the milled kernel

· Sifting - separating small impurities or chips from the milled rice

· Length grading - separating small and large brokens from the head rice

· Blending - mix head rice with predetermined amount of brokens, as required by the customer

· Weighing and bagging - preparing milled rice for transport to the customer
