Visiting the granary of a great country: multi-dimensional upgrades to safeguard the bottom line of food security

China News Service, Tangshan, October 16th (Cao Xufan) From October 13th to 15th, the interview event with the theme "Enter the New State-owned Enterprises - Analyzing the National Industrial Code" went to Tangshan and Qinhuangdao, Hebei Province. The reporter accompanied the delegation to visit the local directly affiliated warehouse of China Grain Reserve Management Group Co., Ltd. (hereinafter referred to as "Sinograin") to observe the facility construction, technical application and people's livelihood security capabilities of my country's grain reserve system from the front line of warehousing.

After years of nationwide layout and construction, Sinopharm’s grain storage network has covered 13 prefecture-level cities in major grain-producing areas, 36 large and medium-sized cities and 48 national grain logistics core hubs, and its hard power in serving and ensuring national grain security has been continuously enhanced. This year, the construction of a new generation of grain air film silos has made key breakthroughs: in July, the country's first batch of 9,000-ton grain air film silos was put into operation in the Changsha warehouse. Its air tightness is more than 6 times that of the national high-standard grain silos, and its thermal insulation performance is 3 times that of traditional shallow round silos. The storage capacity is 20% higher than the previous generation; in September, the first 10,000-ton grain air film warehouse in the northeastern alpine region completed the film blowing operation in the Longjia warehouse, setting a record for the size of a single grain storage facility of the same type in China.

The green grain storage technology system that adapts to the climate difference between the north and the south has achieved 98% application coverage. Relying on internal circulation temperature control technology, the north uses the natural "cold core" of grain piles to achieve cooling in winter and summer use, saving more than 50% of energy compared with conventional grain storage technology. The south promotes the application of nitrogen-controlled atmosphere grain storage technology to suppress pests and delay quality deterioration by reducing the oxygen content in the warehouse, achieving "high-quality grain storage, constant storage and always freshness."

Digital transformation deeply empowers the entire process management of grain storage. At present, thousands of Sinograin's directly-affiliated warehouses and branch warehouses across the country have achieved full coverage of the "technical prevention and technical control" system, relying on artificial intelligence and big data to build a supervision "smart brain", covering five major categories of core supervision scenarios, and promoting the transformation of the management model from "people looking for problems" to "problems looking for people." The intelligent inspection system in the procurement process can complete automatic inspection of the four major staple grains, increasing the efficiency by more than 2 times, effectively avoiding the influence of human factors, and making farmers' grain sales more transparent and more secure.

As an important executive body of national grain regulation, in response to the periodic fluctuations in grain market prices in some major producing areas, Sinograin Group promptly launched the minimum purchase price execution plan and set up nearly 3,000 purchasing warehouses in major producing areas to open for purchase. It effectively played the role of policy support to stabilize the market and stabilize expectations, which not only ensured the smooth operation of the grain market, but also effectively maintained the bottom line of grain sales income for grain farmers.
