A survey by China's National Grain and Material Reserves Bureau shows that the number of losses and losses in China's grain storage links will effectively decrease in 2022, and the loss and loss rate will be significantly reduced. At present, the comprehensive grain loss rate of China's state-owned grain reserve enterprises during the storage cycle is controlled within 1%.
On the 16th, the 2023 World Food Day and National Food Security Publicity Week activities were launched in Nanjing, Jiangsu. According to the relevant person in charge of China's National Grain and Material Reserves Administration, grain-saving and loss-reducing technologies have been implemented and applied throughout China, and the "four-in-one" (grain condition detection, mechanical ventilation, circulation fumigation, and grain cooling technology) grain storage technology has become an important part of state-owned grain depots. Standard. Advanced and applicable green grain storage technologies have been applied across China to reduce grain loss and consumption, and the quality and freshness of grain storage have been continuously improved.
The reporter learned that since 2015, Anhui Modern Grain Logistics Center has independently developed the "Smart Nitrogen" nitrogen grain storage project (using a fixed molecular sieve nitrogen production process to automatically inspect the nitrogen concentration and pressure in the warehouse). Wang Yan, director of the warehouse, said that the controlled atmosphere warehouse currently has a capacity of 140,000 tons, accounting for nearly 40% of the total warehouse capacity. It has solved the problem of pest resistance caused by the long-term use of aluminum phosphide fumigation, further reducing losses while maintaining the quality of stored grains.
Data from the National Grain and Material Reserves Administration shows that China has built more than 5,500 grain post-harvest service centers to provide farmers with cleaning, drying, storage, processing, sales and other services, basically achieving full coverage of grain post-harvest services in major grain-producing counties. . In 2022, 86 grain post-harvest service centers in Shandong Province cleaned and dried 5.18 million tons of grain, saving 210,000 tons of grain. The Yunnan Provincial Grain Post-harvest Service Center cleaned and dried 210,000 tons of grain, reducing losses by 8,000 tons and helping farmers increase their income by more than 4 million yuan.
