Abstract: Several grain storage problems were analyzed in the article in the existing grain storage security system in China, due to the loss of the grain postpartum, and the backward technology and equipment. Relevant data and charts from Jilin Province, taken as an example of China’s major grain producing area, were discussed. The discussion showed that it was necessary to develop the grain drying technology and equipment in grain producing areas. From the current national policy about the grain drying and storage, and the situation of the present grain drying technology, China has the ability to popularize the mechanical grain drying in different rural areas with the supporting techniques. Experts suggest that it takes about 10 years to carry out the project as “Popularizing the Mechanical Grain Drying in Rural Areas” with its aim of “One village with one dryer, and one family with one storage granary”, to replenish the state grain depot, and establish the high efficiency and low loss system of national security grain storage system with the Chinese characteristics.
