How is rice processed into rice?

It is divided into three processes: cleaning, hulling and milling.

The rice grain consists of husk, coat, embryo and endosperm. The purpose of paddy processing is to separate the endosperm from the other parts with minimal crushing to make rice with better eating quality.

Expanded Information:

1, cleanup

Rice grains are mixed with gravel and mud, coal chips, nails, straw and weed seeds and other impurities. Processing process is not clean, not only affect the safety of production, reduce the quality of rice, and harmful to human health.

2, hulling

The process of stripping the husk of rice to make it brown rice. Huller with the machinery called huller, commonly used rubber roller huller and sand plate huller two kinds. Rubber roller huller's main components for a pair of side-by-side rubber rollers, two rollers rotating in opposite directions and different circumferential speeds, the grain through the rolling distance between the two, due to the role of tearing and rubbing and shelling.

3, rice milling

Rice by the hulling and separation of grain and brown net brown rice, the surface of the skin contains more fiber, affecting the quality of food. Rice milling is the skin layer of the brown rice to be milled, so as to become the process of rice. The use of mechanical action to remove the skin layer of the so-called mechanical milling; with chemical solvents to soak brown rice, so that the skin layer softened, and the skin layer and the embryo contains fat dissolved in the solvent, and then lighter mechanical action to remove the skin layer of the so-called chemical milling.
