How is rice processed into rice? What are the steps?

Before processing, the foundation needs to be cleaned, followed by a series of steps such as hulling, rice milling, polishing, and selection。Rice is one of the indispensable staple foods in our daily life, and many people only know how to make and eat it, but they don't know how rice is processed into rice step by step. In fact, there are many links from planting to production, all of which are indispensable.

First of all, the rice grown in the field will be harvested by human or machine means, and after inspection, it will be confirmed that there is no problem, and then it will be sent to a special warehouse in the factory, which we can understand as a preliminary inspection, the purpose of which is to ensure food safety.

Here these paddies.

The first cleaning will be carried out, because in the process of harvesting, storage and transportation, a lot of impurities may be mixed in, and it is more convenient to clean up for subsequent processing.

Secondly, the staff will use a machine to remove the outermost husk of the paddy, which is known as hulling. After this step, we get brown rice.

Brown rice at this time consists of endosperm, embryo and rice bran.

It is composed of three parts, which retains the nutrients of the rice to the greatest extent. With the development of the times, more and more people have begun to pay attention to eating healthy, and brown rice has been favored by many consumers. However, because of the poor taste, in order to be more acceptable to the public, it also needs to go through subsequent fine processing.

Finally, the brown rice that has been shelled goes to the next process, milling the rice. This is also one of the most important procedures, the machine will remove the outermost layer of brown rice, and after this process, it basically meets the requirements of white rice. However, in order to meet the needs of consumers from all walks of life, white rice must be graded, selected, colored, etc., and the price of better quality is relatively high, and vice versa.

Before leaving the factory, the rice also needs to be inspected and packaged for the last time to ensure that consumers can eat it with confidence. After completing this process, the packaged rice can be put on the market for sale.

Rice needs to be refined in a way that can be processed into rice.

In our daily lives, the rice we eat is made from rice, and rice itself is a processed product. In modern society, some people especially like to eat whole grains, and adjust their diet in this way. At the same time, some people are also very curious about how rice is processed into rice, in addition to the traditional process, modern technology can further improve the efficiency of rice processing into rice, I will briefly introduce the steps of rice processing into rice through the following points:

Step 1: Select the rice.

After the rice is entered into the processing plant, the first step is to select it, and the most important step in the rice processing process is the processing of rice milling. The purpose of selection is to ensure that the nutrients in the rice are fully preserved and to avoid differences in the quality of the rice due to different processing techniques. Finally, the rice needs to be selected, and the machine equipment can select some large and small grains in the rice separately, and can also separate the rice grains.

Step 2: Shelling is required.

The selected rice needs to be removed from the chaff, and the main function of the chaff is to protect the grain from mechanical damage. The chaff is usually treated by means of screens, crushers, sorters and crushers. The chaff contains a large number of impurities, which can affect the quality of rice if it is not sorted effectively.

If it is reprocessed into raw materials for the feed industry, it will seriously affect people's health and food safety. Therefore, the state will process the chaff to a certain extent when processing rice. Rice peeling is an important part of rice processing, which is mainly used to remove the skin of rice through physical methods.

Step 3 requires the removal of impurities.

The rice will be crushed 3-4 times before threshing, and the main purpose is to remove impurities such as starch from the rice. Rice bran is an indispensable substance for rice in making rice noodles and grinding flour, and rice bran is generally stored in warehouses in rice mills. The nutrients in the rice bran can be absorbed and utilized by the rice, and it can also reduce the hardness of the rice.

There are three steps required to process rice into rice, each of which is very strict. All the straw is removed and then the rice is placed on the ground and crushed. Not only can it improve the quality of rice, but it can also keep the rice yield high.

It is necessary to do a good job of right and wrong management, so as to ensure that there is not so much debris in the field. If there is one step missing, the rice will definitely not be crushed. Farmers generally put the harvested rice in an empty space to make it, so that they can make certain adjustments to themselves.

After the rice is cleaned, the surface layer must be crushed off. At this time, you can take the rice to the market and let someone else peel it. Because the other party will have a specific machine, the rice will be processed in a unified manner.

Do not choose to soak the rice in a chemical solvent, otherwise you may eat some harmful substances. When others make rice, they will crush out some of the good substances in the rice, and they will feel very delicious when they eat it. <>

When planting rice, there are generally a variety of pests in the field, which is likely to cause a series of bacteria to appear on the rice. Be sure to manage it in a timely manner, and if you find a problem, you can go to a professional person to solve it. Do not choose to plant and ignore it, then the disease and insect phenomenon of rice will be more serious.

You can choose to spray it several times every 5 or 7 days, so that you can protect yourself to a certain extent. <>

In general, there is generally farmhouse fertilizer in rural areas, and these fertilizers can be managed in a unified manner. Fermentation is required, otherwise the bugs inside will surely take root in the field. The farmhouse manure can be turned over repeatedly for drying, and in this way, it can be fertilized quickly.

It is necessary to speed up the growth rate of the plant, so that the rice can quickly enter the tax-saving period. If the farmhouse fertilizer is not good, then potassium fertilizer should be used as the main fertilizer, which will have a good effect.

The rice needs to be cleaned and then dried, and the workers will decompose the rice and then process it; If rice wants to be turned into rice, it needs to be washed, then hulled, and finally milled.

It needs to go through the right processing steps; The rice needs to be cleaned, hulled, milled, and then dried for dehydration, and then packaged.

Therefore, when processing rice, it also needs to go through some processing methods, and these three steps are cleaning, hulling, and milling.

There are three steps required to turn rice into rice, which are cleaning, hulling, and milling, where cleaning is to remove the rice.

in the soil, straw, sand.

Wait for the debris to be cleaned up, and finally use mechanical action to crush the brown rice.

Cortex, improve the quality of rice, in addition, if you want to have a high yield of rice, you need to apply fast-acting organic fertilizer one week after planting to speed up the growth rate of the plant.

Rice into rice needs to go through three steps: cleaning, hulling, and milling, in which cleaning rice is to clean up the soil, straw, sand and gravel in the rice, which is conducive to improving the quality of rice, in addition, if you want rice to have a high yield, you need to do a good job in fertilization management.

After the rice is cleaned and hulled, the cortex on the surface of the rice needs to be crushed to complete the transformation of rice.

If you want to have a high yield of rice, before planting, apply farmhouse fertilizer, ammonia fertilizer, phosphorus and potassium fertilizer and other fertilizers to the soil as basal fertilizer to improve soil fertility and air permeability, and wait for a week after planting, apply fast-acting organic fertilizer to speed up the growth rate of the plant, and when the rice enters the heading stage, apply fertilizers based on potassium fertilizer.

Common pests and diseases of rice are leaf rice blast, ear rice blast, white leaf blight, bacterial stripe spot, etc., when leaf rice blast appears in the field, it is necessary to use 20% tricyclazole wettable powder dilution to prevent and control, generally sprayed once every five to seven days, sprayed twice in a row.

1. There are several steps required for rice to be processed into rice.

1. Rice cleaning and rice grading: most of China's rice is produced by individual farmers, with many varieties and miscellaneous, and poor conditions during harvesting and drying, so there are more impurities in raw grain, which brings greater difficulty to the classification and processing of rice. In the final stage of the cleaning process, large factories will grade the rice according to its size, separate the hulling and milling rice, and select the appropriate technical parameters when the equipment is milling, reduce broken rice, and package large millet grains separately, which can effectively improve the value of the commodity.

2. Back balan processing and brown rice quenching: Large factories use back balan grain for separate processing. After hulling, the rice that has not been hulled is rolled again, and the unhulled rice is put into the husking machine, which is easy to produce the phenomenon of waist bursting and broken rice.

It is necessary to adjust the machine parameters reasonably, which can not only reduce the brown broken rice, but also reduce the power consumption of the equipment.

3. Multi-lane rice milling and rice polishing: multi-lane rice milling, the pressure in the rice milling machine is small, the endosperm is less damaged, the broken rice is less, the rice yield is higher, and the rough-white unevenness rate is reduced. Rice polishing is an indispensable process for processing refined rice.

Polishing uses friction to remove the floating bran on the surface of rice grains, improve the finish of the surface of rice grains, and is conducive to the preservation of rice.

4. Rice color sorting: color sorting is used to remove heterochromatic impurities in rice, which is an important process to ensure product quality in the production of refined rice and export rice. Large factories often use a single color sorter to process the rice color sorting stage.

5. Prepared rice: Mix two or more kinds of rice together in a certain proportion as a rice product. Rice with different nutrients and tastes is blended to achieve complementary strengths and weaknesses, thereby improving the nutrition and taste of rice.

6. Packaging: At present, the finished rice on the market is mainly packaged in 5 kg and 10 kg textile bags, and the high-quality rice is packaged in vacuum and nitrogen to ensure the freshness of the rice.

2. Is rice a coarse grain?

1. Rice belongs to coarse grains and fine grains, and can also be between coarse grains and fine grains, and the classification of rice depends entirely on the processing method.

2. Rice only retains the endosperm, which belongs to fine grains; After fine milling, rice still retains the husk, endosperm, germ, etc., which belongs to coarse grains; After processing, the husk and aleurone layer are removed, but the endosperm and germ are retained, and this type of rice is "embryo rice", which is between coarse grains and fine grains.

Rice processing is divided into three processes: clearing, hulling and milling.

1. Cleaning: Rice is mixed with a variety of impurities such as sand, soil, coal dust, iron nails, rice stalks and weed seeds, which are not cleaned during processing, which not only affects safe production and reduces the quality of rice, but also harms human health. Cleaning methods include screening, selection, winnowing, magnetic separation, and specific gravity separation.

2. Hulling: the process of stripping the husk of rice to make it brown rice. The machinery used for hulling is called hulling machine, there are two kinds of rubber roller hulling machine and sand tray hulling machine commonly used, the main component of rubber roller hulling machine is a pair of parallel rubber rollers to shoot the lead trapped cylinder, the two rollers rotate in opposite directions and the circumferential speed is different, and when the grain passes through the rolling distance between the two, it is shelled due to the tearing action; The sand disc hulling machine has two round golden rigid grinding discs up and down, the upper sand disc is fixed, the lower sand disc rotates, and the grain is shelled by the force in the gap between the two sand discs.

3. Milling rice: The net brown rice made by hulling and grain roughness separation of rice has more fiber on the surface of the cortex, which affects the quality of eating.

1. After the raw rice is inspected, it is sent to the factory and stored in the special dust warehouse of the manuscript Bizen. Rice processing is carried out in a rice workshop;

2. First of all, the cleaning of rice is to clean up all kinds of impurities that may be mixed in the process of growth, harvesting, storage and transportation of rice;

3. Then the rice is husked to obtain brown rice, which is commonly known as hulling;

4. The next process is rice milling, which is also one of the most important processes in rice processing. The skin layer of brown rice is removed to make white rice that meets the quality requirements;

5. Such white rice is then graded, selected, polished and color-selected to make rice for people to eat;

6. The rice must be inspected and packaged before leaving the factory, and finally it will be the best finished rice on the market.
