The Research Of The Grain Warehouse For The Periphery System

Grain has been considered as important strategic material, Rulers of each dynasties attach great importance to food safety. For the consideration of war,administrators need to guarantee the food supply’s self-sufficient, food shortage leads by war in Africa is a good example demonstrating the importance of food security.China is a country with a large population which also has huge grain consumption,“there are two stages which are prenatal and postpartum divided by the harvest, " The postpartum stage includes acquisition, sale, transportation, storage, processing, import and export, etc. In the postpartum period. Key for food security during postpartum stage is the improving of grain purchase, transportation, storage, processing methods and reducing of postpartum grain losses. It also requests us to improve the quality and comprehensive utilization rate of grain, advocate scientific diet, even reducing food waste. " [1]Our country constructed series of modern granary in late 90 s last century, which releases pressure for grain porches and storage in certain distend. However, limited by technical conditions at that time, our granaries are in the lack of scientific thermal calculation. It influences the heat insulation and airtight performance, meanwhile causes significant damage on grain quality.In order to ensure food security and improve the grain quality during storage to achieve low-temperature preservation, except retain the traditional technologies such as ventilation and mechanical refrigeration, I also introduce comprehensive technical measures of "air tightness and heat preservation " which are crucial to grain preservation.According to standard for low-temperature environmental-friendly grain storing,my project took the perspective of widely applying energy saving material and new construction in architectural design, wall construction and foundation practicing. It focuses on natural ventilation, highly compatible design for temperature, even improvement of heat insulation and airtight for different granary construction. Thus developments our own grain storage patent on integrated technology of thermalinsulation and air tightness of grain storage.
