    "On the one hand, we spend a lot of time to increase grain production, on the other hand, the food we already have is wasted because of inadequate storage, improper storage and other factors, which is a very inexpensive thing." Yan Bo, Director of the Policy and Regulation Department of the State Food Administration, said that in vigorously promoting grain saving and loss reduction, the state comprehensively promoted new facilities, new technologies and equipment for grain saving and loss reduction. Through the implementation of scientific grain storage project for farmers, new grain storage equipment was distributed to farmers, and the technology of grain storage was guided, and obvious results were achieved.
In order to ensure consumer's food safety, advanced grain storage technology has been widely used in grain storage warehouses at all levels and grain processing enterprises throughout the country, which effectively solves the problem of mildew and insect prevention and freshness preservation in grain storage and ensures that stored grain is always fresh.
_With the continuous upgrading of grain storage technology, the quality of stored grain in China has been significantly improved. Central grain depots, local grain depots at all levels and grain processing enterprises throughout the country have widely adopted mechanical ventilation, circulation fumigation, grain cooling and grain condition monitoring "four in one" grain storage technology, effectively solving the problem of disease in grain storage. According to estimates, after using this technology, the depletion rate of central grain reserve decreased from 4% to less than 1%, the suitable storage rate increased from 70% to 99%, and the use of chemical agents for grain storage decreased by 80%.
At the same time with the upgrading of storage technology, the concept of grain storage in China is also changing and developing towards the transformation of ecological grain storage. Central grain depots, local grain depots and some enterprise grain depots are promoting the use of non-chemical drug control technology to reduce the use of chemical agents in grain storage. The technology of heat insulation and cold preservation, circulating ventilation under film and slow-release ventilation has been popularized in the direct warehouses of middle grain storage in Northeast, Northwest and North China, and good results have been achieved.
