From rice to rice, it's so simple to just fade the chaff? It's not really the case. In the deafening sound of the machine, a piece of rice becomes a crystal rice, which has to experience countless vibrations and shocks, and the loss rate of rice in the processing process is as high as 10.95 percent.

Jingshan bridge meters, China's national geographical indication products. As one of the initiators of the "Jingshan Bridge Rice" industry alliance, Hubei Hongsen Industry (Group) Co., Ltd., its annual output of 500000 tons of intelligent rice production line will effectively reduce the loss rate of rice in the processing link, and will be included in the provincial grain bureau to unveil the list of scientific and technological projects. At the same time, the promotion of this project has attracted the participation of many leading enterprises of grain machinery and equipment in our province, realizing the joint training of "sharing data and cooperating with each other" on the same assembly line, forcing scientific and technological innovation with the project, forcing the country's first digital intelligent production line for rice processing, and driving the transformation and upgrading of Hubei grain machinery and equipment industry.

Break 2 grains of rice less and harvest 285000 tons of grain more.

On September 4, a full-media reporter from Hubei Daily came to Hubei Hun Sen Industrial (Group) Co., Ltd. located in Shayang, Jingmen. Only on the rice processing production line, from raw materials into the warehouse, impurities removal, to grain of rice after stone removal, grain husking, screening, rice milling, polishing, color selection, metering and bagging, all were controlled by computers. All links were automated and only two staff monitoring systems were required.

"Automation requires people to operate and adjust on site. Intelligence only needs to set parameters on the computer." Li Junfei, director of the production department of Hun Sen Company, said that after the upgrade, labor intensity was greatly reduced and the working environment was also improved. The operator does not have to patrol frequently in the roar of the machine, just sit in a comfortable and clean monitoring room and switch the silo with a click of the mouse. On the big screen, the remaining warehouse capacity is clear at a glance and is no longer estimated by experience. Insufficient feeding will be warned 30 seconds in advance. Even if manual treatment is not timely, there will be a flow buffer function. When the feeding is empty, the machine will automatically stop and wait to prevent scattered brown rice from being broken by the machine. This can not only reduce the broken rice rate, but also save energy.

Before the voice fell, the monitoring room sounded a buzzer, and the red alarm light flashed on the top of the cabinet. The staff calmly walked to the computer to check. In the production line flow chart on the screen, a rice mill was automatically offline and displayed relevant fault parameters. According to the map, two staff members cooperated. One found the corresponding control components from 17 cabinets to reset, and the other went to the production workshop to check the fault and restart the machine. The faulty machine returned to normal operation within 5 minutes.

"The most important thing is that the rate of broken rice has been reduced." Li Junfei said happily that the network interconnection of all kinds of grain machinery equipment has greatly reduced the processing energy consumption and increased the whole rice rate by 2 percentage points, "equivalent to 100 grains of rice, with 2 grains less broken." The value of whole refined rice is much higher than that of broken rice, which effectively improves the economic benefits.

To detract is to increase production. It is understood that at present, the average rice yield of japonica rice in China is about 65%, and that of indica rice is about 63%. After this intelligent system, the rice yield increased to 66.5 percent for japonica rice and 64.5 percent for indica rice. As one of the most important rice producing areas in China, Hubei Province has a annual output of about 19 million tons of rice, accounting for 8.8 percent of the national output. If the loss is reduced by 1.5 percentage points, it will be an extra 285000 tons of grain.

One Grain of Rice Makes Grain Machinery Enterprises "Joint Training"

"This production line is not only Hun Sen a rice factory to benefit, the Hubei grain machine industry is also of great significance." On September 7, as the leader of the "unveiling" of the project, Zhou Jin, director of the Department of Electrical Engineering of Wuhan University of Light Industry, introduced to reporters that the Provincial Grain Bureau attracted many grain machinery equipment companies in our province to participate in the way of unveiling the list. The project forces technological innovation.

"Hulu, with Yongxiang; rice, is the machine star; polishing, chose the golden grain; grain rough separation sieve, is flying to the bell..." Zhou Jin is like a few treasures. According to reports, this intelligent assembly line has gathered the leading products of Hubei's top grain machinery equipment enterprises. Hubei Yongxiang Grain Machinery Co., Ltd., Wuhan Zhongjixing Grain Machinery Co., Ltd., Wuhan Jinhe Grain Machinery Co., Ltd., Hubei Feilai Zhong Grain and Oil Equipment Co., Ltd. and other leading enterprises in Hubei are all in the vanguard in the national market.

Zhou Jin said that since rice processing is a low-profit industry, enterprises are very cautious in their investment in new equipment. Thanks to the bonus and subsidy funds of the "list unveiling system", processing enterprises have the confidence to try a full set of upgrades. Grain machinery enterprises have the opportunity to introduce innovative equipment and show their skills on the assembly line.

Temperature, humidity, pressure, flow, vision, location... This production line is equipped with a large number of sensors, and the information of all equipment is aggregated into a database. "In the past, each device fought alone, but now it shares data and works together. Through this project, it will give Hubei grain machine leading enterprises a chance to jointly train troops." Zhou Jin said that modeling is currently under way, and the prototype of the "production link" of the digital twin factory has been initially set up.

"This is the country's first rice processing digital intelligent production line." Zhang Yonglin, executive chairman of the Grain Machinery Branch of the Provincial Grain Industry Association, said that Hubei grain machinery companies should cherish this opportunity, develop and improve products, strengthen collaboration and exchanges, and turn the "vanguard" into a "strengthening company".

"The unveiling of the list of grain science and technology projects can effectively promote the research and development and application of common and key technologies in the industry." Li Shuo, deputy director of the Provincial Grain Bureau, said that the next step will continue to increase the exploration and support for the unveiling system, promote the precise docking of enterprises, universities and scientific research institutes, and strive to solve major scientific and technological bottlenecks and key technical problems that restrict the development of industrial upgrading. Grain circulation development and food security provide strong scientific and technological support.
