Green storage achieves quality preservation, loss reduction, energy saving and consumption reduction
Recently, the national key research and development program "Modern Grain Depot Green Grain Storage Project" was officially approved and launched for implementation. The approval and implementation of the project is of great significance to China's food security.
Grain is a basic necessity for human survival. Safeguarding national food security is a major strategic issue of overall importance to China's national economic development and social stability. At the end of 2013, the CPC Central Committee put forward a new national food security strategy of "relying mainly on ourselves, basing ourselves on domestic production, ensuring production capacity, moderately importing, and supported by science and technology", and clearly set the new goal of "basic self-sufficiency in grains and absolute security of staple food". The coming years are a critical period for China to build a moderately prosperous society in all respects, and also a crucial period for comprehensively deepening reform and accelerating the transformation of the economic development model. The realization of the grand goal of "building a moderately prosperous society in all respects" requires us not only to provide the public with an adequate and stably supplied quantity of grain, but also to pay more attention to the quality and nutrition of grain; the increasingly severe resource and environmental situation forces us to further improve the environmental performance and efficiency of grain storage and logistics technology; the acceleration of urbanization and population aging, together with the structural shortage of labor, requires us to further raise the level of mechanization, automation and intelligence in operations.
On the basis of comprehensively reviewing the technical bottlenecks restricting grain storage enterprises in "green storage, quality preservation and loss reduction, energy saving and consumption reduction", the "Modern Grain Depot Green Grain Storage Project", through applied research, breaks through in a categorized manner the key materials, technologies, processes and equipment in each stage of grain depot production; in conjunction with the implementation of the national "Grain Security Project Construction Plan" and the construction of new grain depots with a capacity of 100 billion jin, it demonstrates the project's results in typical settings, building more than 50 demonstration depots in different grain storage ecological zones, and gradually extending them from point to area, so as to achieve the goals of green, quality-preserving, energy-saving and loss-reducing modern grain depots.
The implementation of the project can provide effective technical support for "ensuring the security of staple food". The grain storage quality preservation technology developed by the project can delay changes in grain quality. Through the research, development and demonstration of non-chemical control of stored-grain pests, the project can provide reassuring, fresh and high-quality grain for "Healthy China", effectively safeguarding the security of staple food.
The implementation of the project can ease the pressure on China's resources and environment. At present, China's grain production is constrained by land and water resources, and increases in total output and yield per unit area have encountered bottlenecks. By developing grain storage loss-reduction technology, this project reduces losses during grain storage, which is equivalent to developing invisible farmland.
The project can effectively raise the production efficiency of the grain storage industry and reduce labor intensity. The grain industry is a traditional industry, where a great deal of work needs to be done manually or with manually operated machinery, which is time-consuming and labor-intensive, and the working environment is dusty. The new grain cleaning, loading and unloading, dedicated refrigeration, circulation temperature equalization equipment and automatic control systems developed by this project can effectively raise the level of mechanization and automation in the grain storage industry and effectively reduce labor intensity.
The smooth implementation of the project will effectively promote leapfrog development of China's grain storage industry and provide effective technical support for China's food security.
