Raw grain cleaning (drum primary cleaning screen, vibrating screen, stone remover)

Shelling (that is, hulling, using a sheller, usually equipped with air separation, can remove rice husk)

Coarse-grained mixture separation (coarse-grained separation screen)

Separate immature grains from brown rice (usually used by large rice mills)

Rice milling (rice milling machine, generally one sand and two irons, plus polishing machine can also be regarded as three irons, and the north and south rice are different)

White rice grading (white rice grading screen)

Color sorter (color sorter, the highest-grade color sorter in the domestic market at present is the Z series of Setex in Buhler, Switzerland, and the price of talents is also higher).

Polishing (some millet factories put this before color selection)

rice

Rice is the finished product of rice after washing, hulling, milling and finishing. ? Rice embryo and aleurone layer contain nearly 64% of rice nutrition and more than 90% of nutrients needed by human body, which are the main foods of southerners.

The efficacy of rice

1. Infant supplementary diet

It is beneficial to the development and health of infants, can stimulate the secretion of gastric juice, help digestion and promote the absorption of fat, and can also promote casein in milk powder to form loose and soft small clots, which are easy to digest and absorb.

2. Basic food for supplementing nutrition

Rice porridge has the effects of invigorating spleen, regulating stomach and clearing lung heat.

nutritive value

Rice contains about 75% carbohydrates, 7%-8% in protein, 1.3%- 1. 8% fat and rich in B vitamins. The carbohydrate in rice is mainly starch, and the protein in rice is mainly glutenin, followed by glutenin and globulin. Its protein biological value and amino acid composition ratio are higher than those of wheat, barley, millet, corn and other cereal crops, and its digestibility is 66.8%-83. 1%. It is also one of the higher cereal protein.

Therefore, edible rice has high nutritional value. However, the content of lysine and threonine in rice protein is less, so it is not completely protein, and its nutritional value is not as good as that of animal protein. But eating rice for lunch and dinner is better for people to lose weight than pasta. In the south of China, people generally take rice as their staple food, but it is very different in the north.

The fat content is about 9%, and the linoleic acid content in the fat is relatively high, generally accounting for 34% of the total fat, which is 2-5 times higher than that of rapeseed oil and tea oil respectively.

Crops (millet), rice, millet (sorghum), wheat and glutinous rice (beans) are collectively called "five grains". Rice is raw rice.
