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

Hulling (that is, hulling, using hulling machine, usually equipped with air separation, can remove rice husk)

Grain-coarse mixture separation (grain-coarse separation screen)

Separate immature grains from brown rice (generally 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 rice in the north and south is different)

White rice grading (white rice grading screen)

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

Polishing (some millet factories put this before color selection)

White rice grading

rice

Rice is the finished product of rice after cleaning, husking, milling and finishing. ? Rice embryo and aleurone layer contain nearly 64% of rice nutrition and more than 90% of the nutrients needed by human body, which is the main food for people in the south.

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, making it easy to digest and absorb.

2. Basic food supplemented with nutrients

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

nutritive value

Rice contains about 75% carbohydrate, 7%-8% protein, 0/.3%-1.8% fat, and is 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 has higher biological value and amino acid composition ratio than other cereal crops, such as wheat, barley, millet and corn, and its digestibility is 66.8%-83. 1%, which 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 a complete protein, and its nutritional value is not as good as that of animal protein. But eating rice at lunch and dinner is more beneficial for people to lose weight than pasta. In southern China, people generally eat rice as a staple food, but it is very different in the north.

The fat content is about 9%, and the linoleic acid content in its 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 called "five grains". Rice is raw rice.
