Rice processing in Lingling area in the late Qing Dynasty used traditional methods such as stone mortar, pit piling, stone grinding and bamboo pushing. One stone of rice is used to process four barrels of five liters of rice.
In the early years of the Republic of China, China introduced rice mills to process rice. In the 1930s (194 1), there were two rice mills in Qiyang and Lingling counties. In that year, the commissary valley processed 5.353 million gems. In 33 years of the Republic of China (1944), the Japanese army occupied the territory, the government-run and foreign-funded rice processing factories moved away, and the local rice factories closed down or closed down. In 38 years (1949), there was no machine rice mill in China. At the end of 1949, when the whole region was liberated, rice processing was still indigenous, and it was supplied to the army, government officials and citizens, and was entrusted to rice merchants, handicraft citizens and farmers in four townships for processing. 1950 In May, China Grain Storage Yongzhou Branch organized 100 workshops to process rice by traditional methods. After processing, 67 kg of medium-cooked rice was harvested per 100 kg of rice, which was 650 tons of processed rice in the whole region. At that time, the government actively built state-owned rice mills and supported private rice mills. 1950 The state-owned rice mills established in that year include Shengli Rice Mill in Special Zone, Dong 'an Power Plant Rice Mill and Limin Rice Mill in Daoxian County, which processed rice 1745 tons. 1952, there are 9 state-owned rice processing plants in the whole region. 1950, two private rice mills, lianfeng and Xinfeng, were established in Lingling county. 1952, and two private rice mills, gonglian and cooperative, were completed and put into operation. After the implementation of grain purchase and marketing, private rice mills began to transform in the form of unified management and entrusted processing. Six private rice mills closed down three times, and three were public-private partnerships 1956. 1954 to 1955, Lanshan rice mill and Xintian rice mill were completed and put into operation. 1957, state-owned rice processing plants in the whole region processed rice 18400 tons. 1 959 May1day, lengshuitan Wuyi Rice Factory was completed and put into operation, with an annual processing capacity of 40,000 tons, accounting for 40% of the whole processing capacity. 1965, the number of state-owned rice processing plants in the whole region increased to 13 (excluding Qiyang, the same below), with an annual processing capacity of 97,500 tons, or 38,300 tons of rice. At the same time, rural communes and teams used small rice mills, and local processing was gradually eliminated. After 1966, the task of rice blending (discharging) in the whole region increased year by year, and the rice processing capacity was enhanced. The whole region processed 67,200 tons of rice, an increase of 28,900 tons or 75.4% compared with 1.965. In the early 1970s, rice aided by Vietnam was processed, and1971-1975 * * * exported rice173,000 tons. In 1978, there were 2 1 rice mills in the whole region, processing 97,800 tons of rice, an increase of 30,600 tons or 45.5% compared with 1966. The average rice yield per 100 kg is 70.8%, and the processing cost per ton of rice is 4.53 yuan. 1979, the grain transferred from outside the region decreased. In that year, the whole region processed 28,900 tons of rice, a decrease of 68,900 tons over the previous year. After 1980, rice processing turned to pay attention to economic benefits, and at the same time, the equipment of state-owned rice mills was used to process on behalf of farmers. 1986, there were 26 state-owned rice mills (including qiyang county) in the whole region, processing rice 130400 tons. From 1988 to 1989, the processed rice in the whole region is 1 19000 tons and 98400 tons respectively. After 1990, the rice processed by private millet factories gradually flooded into the market, while the processing capacity of state-owned rice factories gradually declined. All grass-roots grain enterprises in the whole region have set up 34 small rice mills, equipped with complete sets of combined rice mills to process rice on behalf of farmers, processing 23,800 tons 199 1. 1995, the number of rice mills in grass-roots grain enterprises in the whole region has grown to 7l, and the whole region processes rice 108 1 10,000 tons, of which 7 1 small rice mills process 59,600 tons, accounting for 54.7%. 14 independently accounted that the rice mill processed 48,500 tons, accounting for 45.3%.
Since 1970, famous experts in grain industry, dust removal technology and senior engineers have played a leading role in the design and construction of rice mills in Lingling area (Yongzhou city) and the research and development of related equipment of rice mills. /kloc-0 was born on October 25th in Taojiang County, Yiyang City, Hunan Province. June 65438+July 0970, graduated from Zhengzhou Grain Institute (now Henan University of Technology). He has served as chief of industrial section of Lingling Grain Bureau, deputy director of regional grain bureau, chief engineer of Yongzhou Grain Bureau and department-level researcher. 1987 was elected as a director member of China Cereals and Oils Society, Provincial Commercial Society and Provincial Feed Industry Society; Since 1988, he has been elected as a member of the Standing Committee of the National Grain Pneumatic Transportation Committee and a visiting professor for 20 consecutive years; In 2000, he was elected as the technical consultant of Xinhua News Agency Hong Kong Branch. Domestic and foreign grain systems compete to hire him as a technical consultant, and respectfully call him "He Laoshi". He was once rated as "advanced worker", "outstanding scientific and technological worker" and "advanced individual in scientific and technological development" in Hunan Province.
Accumulated the technical data of rice processing dust removal 1 10000 words, held 46 technical training courses, published more than 10 national papers and 7 provincial papers, and won many "excellent paper awards" at all levels. The new technology of dust removal and high-efficiency back-blowing dust removal in rice mill was selected as "World Patent and Technology" by Xinhua Communication Hong Kong Branch. Often attend domestic grain industry meetings. Since 1988, he has published papers at the national air transport academic conference every year, and has been hired to give lectures and give lectures on the spot all over the country, which is very popular and enjoys a high reputation among his peers in the country. He persisted in carrying forward the team spirit, worked with colleagues, technicians and workers to tackle key problems, and successfully solved six technical problems in rice processing, such as husk separation, roughing, yield, power consumption, glue loss and broken rice, and successfully developed "LGF-0 1 husk separation device", "pneumatic conveying technology of single rice mill" and the 30-year-old rice mill designed, built and guided by him. He presided over and participated in the design of grain enterprises and grain and oil machinery enterprises in Yongzhou, Changsha, Xiangtan, Hengyang, Changde, Yueyang and Zhuzhou, as well as in Sichuan, Guangxi, Guangdong, Heilongjiang, Jiangsu, Zhejiang, Shanghai, Beijing and Henan provinces and cities.
