China is a big country in grain production, storage and consumption. Food security is a major strategic issue related to the national economy and people’s livelihood. According to the announcement of the National Bureau of Statistics on the grain output in 2016, China’s total grain output in 2016 was 61,623.9 million tons, of which 56,516.5 million tons were cereals. However, the degree of mechanized grain drying is relatively low in China. The level of mechanized grain drying is less than 10%, which is the “short board” of the whole mechanization of agriculture.
