How does a modern assembly line workshop turn rice into rice?

How is the rice we usually eat processed? In fact, the rice processing process is relatively complicated. It takes about ten steps from harvesting to distribution to the market.

First, during the harvest season, the harvester begins to thresh the rice, and then transports it to the storage shed. The ventilation equipment in the shed first dries the rice, during which the probe will take samples of the rice. After being sent to the technical department, the master will conduct a humidity test. When the moisture content reaches about 14%, it meets the next processing standard. Before the rice enters the warehouse, the rice should be classified into varieties, and the variety, grade, and warehouse number to be entered should be noted on the quality inspection form. Rice of the same variety and different grades should be stored separately if needed for production. , to facilitate future processing. The rice will then be sent to the rice mill, where it will be shelled using a rice mill. Before that, a separation screen will be used to filter out residual insects, various stones, foreign matter, etc. in the rice to ensure that each grain of rice is quality.

Second, following the material rice milling process, a small part of the grains will inevitably be missed during the rice hulling process, so the separation screen will be operated several times until all the rice is After complete shelling, these bone shells produced after rice milling will not be discarded. The machine will break them and use them as feed for livestock. At this time, the rice is just beige brown rice, so it still needs to go through the process of grinding and polishing to remove the bran powder on the surface of the rice. After being processed by the polishing machine, each grain of rice will become crystal clear and have a pearl-like texture. luster.

Third, there is an important color selection link. The detection camera will analyze the color and size of the rice, and sort out all the rice grains that do not meet the standards, and use them to make other food raw materials, or It is sent to feedlots as feed for animals. The finally formed rice will be divided into different grades according to their respective qualities, packaged, and finally shipped to supermarkets in various places for sale.
