Due to its location in the high temperature and high humidity areas in the south, the food storage environment is poor, insects, molds, rodent pests, and livestock and poultry feed are serious. The amount of post-production losses is huge. The reporter recently learned from interviews in Guangxi and Hunan that due to the backwardness of grain storage technology and the limited facilities, the loss of grain in Guangxi is about 1.35 billion kilograms, which is equivalent to 1.7 million mu of output. The annual loss due to improper storage in Hunan is about 2 billion kilograms. . Experts suggest that we should further increase scientific and technological support and reduce food loss by adopting advanced drying equipment and improving storage.
Due to poor storage conditions in some areas, the food waste is high. The soil in Hanshou County, Changde City, Hunan Province is fertile, with an annual output of over 1000 kg of rice in two crops per acre. However, high losses coexist with high production. According to reports from large planters, due to lack of drying areas and storage facilities, the amount of grain that has been mold-destroyed and eaten by rats accounts for about 20% of the total grain output.
Every year during the busy farming season, Sun Wenxian, a large planter in Dananhu Township, Hanshou County, has almost no sleeping time, but he still cannot finish drying hundreds of thousands of kilograms of rice in a short period of time. In addition to the lack of venues, drying rice has become a hassle. He said that the largest area of ​​the local tarpaulin is only 2 acres, and it can maximally burn more than 10,000 kilograms of rice at a time. "Especially in autumn and winter, there is more rainy weather. Once the bad weather lasts for a long time, rice drying becomes a big problem."
The reporter learned that "the more production, the greater the loss" has become a headache for many large planters. Song Lianfa, a peasant in Dananhu Township, stored more than 10,000 kilograms of rice in September last year. He suffered a rat problem and lost 150 kilograms in more than six months. Song Lianfa’s “granary†was in his old house. Both doors were made of wood. The holes that were bitten by the rats were fist-sized, and the packed rice was scattered.
Reporters visited some counties and districts in Guangxi and learned that many grain storage facilities at the grass-roots level are backward, and some grain repositories were even built in the 1950s, affecting the security of grain storage. There are 14 grain banks in Xingye County, of which more than 10 food centers are located in townships. Wang Yongguang, manager of the Xingye County Grain Reserve Management Company, told reporters that he would go to towns and townships every week to check the food storage situation. “Every grain bank has to carry out inspections of temperature, mildew, insect pests and other indicators, and the workload is large.â€
China should vigorously improve grain storage technology. The grain department should use new facilities, improve the grain storage environment, and increase work efficiency. In view of the fact that the city’s food acquisition equipment is backward and the environment for storing grain is poor, the National Development and Reform Commission and the State Grain Administration officially launched the special work of scientifically storing grain for farmers in 2010, which was built for farmers through a combination of central and local subsidies and farmers’ self-raising. Small iron grain store. In addition, grain storage and storage should be mechanized, storage to achieve mechanical ventilation, fumigation to achieve drug circulation, inspection of electronic measurement, and temperature measurement to achieve computer control. Through the use of new facilities, the cost of food export and storage is effectively reduced, labor intensity is reduced, work efficiency is improved, and food quality is ensured.
The grain sector is innovating new technologies, striving for green grain storage and ensuring food security. In the past, food fumigation has been using conventional fumigation, which not only uses more drugs, but also may contaminate food. It also has high costs and labor intensity. Through technological breakthroughs, scientists and technicians have innovated the new technology of circulating fumigation under the membrane, which has effectively suppressed the deterioration of food and caused almost no yellowing of stored grain. At the same time, they also innovated the new technology of mechanical ventilation and grain protection to perform dynamic tests to avoid short circuit or condensation of ventilation and ensure stable temperature of grain piles in the warehouse.
The grain sector adopts new methods to improve the quality of food and create economic value. In the grain supply, a new method of moisturizing and ventilation was adopted to reduce the loss rate of stored grains from the original 1.8% to 0.96%, and the moisture content of stored grain was controlled at about 13.5%. By adopting the new ventilation method of appropriate dehumidification during the grain harvesting period, moisturizing during the grain supply period, and increasing graininess during grain yield, grain moisture and losses are effectively controlled and reduced, and the economic value created in one year alone reaches 1 million yuan. In order to solve the problem of grain and agricultural products selling food that is slightly excessive, the food storage and storage department adopts a method of drying in warehouses, puts the food with excessive moisture into a designated warehouse, and applies a centrifugal fan to send dry and hot air into the grain piles to achieve the purpose of drying food. It ensured the security of high moisture storage grains and reduced the loss of food storage by 1.5%.
China’s grain sector should use new facilities, innovate new technologies, adopt new methods, continuously increase the level of scientific grain conservation, and increase grain storage to a new level, and make every effort to ensure that grain reserves reach the “one symbol, four none†(“one symbolâ€) account. Accounts and accounts are in accordance with each other. "Four nos." means no pests, no deterioration, no sparrows, no accidents.) The safe rate of grain storage reaches 100%, achieving "low loss, low pollution, low cost, high quality, and high Nutrition, high efficiency."
Therefore, the China Food Machinery and Equipment Network Xiaobian believes that the development of the grain drying industry, the acceleration of mechanization of grain production, and the minimization of the loss of stored grain are important ways to ensure high yields and stable total grain, and also directly affect the level of grain. , Processing quality and food quality, thus affecting the economic efficiency of people and food circulation enterprises and people's quality of life, affecting the enthusiasm of food and agricultural grain business operators.
