With the change of international grain market, the centralization of land circulation to promote the development of large-scale agriculture and the adjustment of agricultural machinery subsidy policy, the grain dryer, once a "small, cold" machine, has become hot and has become the next blue sea in the agricultural machinery industry.

    China is the largest food producer and consumer in the world, with an annual total grain output of 610 million tons. According to statistics, the postpartum loss of grain caused by mildew is as high as 21 million tons each year, accounting for about 4.2% of the total grain output in China. It is urgent to develop grain drying. "Timely drying and safe warehousing" is the last key link of the whole mechanization of grain production to solve the problem after harrowing and harvesting. At the same time, grain drying is of great significance to national food security, agricultural production efficiency, agricultural product quality and farmers'income. The necessity of developing grain dryer is analyzed from the aspects of traffic safety, food security, agricultural modernization and human health.
1. Reducing traffic accidents
On the one hand, farmers occupy roads for food drying, which results in road traffic jam, collision and friction accidents when they meet vehicles; on the other hand, farmers set glass bottles, bricks and other roadblocks on the road when they sun grain, and motor vehicles, electric vehicles and pedestrians are prone to traffic accidents and accidents after collision with roadblocks. Hurt.
Every year during the grain drying season, there are many news reports about motor vehicles, electric vehicles and other traffic accidents caused by drying grain on rural roads. According to statistics of relevant departments, in areas with high prevalence of grain dryers, the traffic accident rate is far lower than that in areas with low prevalence of grain dryers.
2. Guarantee human health
Food is dried on the road, and some harmful substances such as gravel, glass bottle residue, bird manure, automobile exhaust and so on infiltrate into the grain. These harmful substances can not be completely treated in the process of food processing, and eventually are eaten by human beings, which directly or indirectly causes stones, stomach ulcers and other diseases.
In areas without dryers, large quantities of grain can not be dried and dried before drying, which results in mildew. Some of the mildewed grain is purchased by flour mills as feed. After being eaten by livestock, livestock is eaten by human beings, which indirectly affects human health. Some mildew (including aflatoxin) grains are directly processed into food processing plants and processed into food for human consumption, which reduces human immunity, increases the risk of cancer, and reduces life expectancy.
3. Ensuring Food Security
Grain drying is of great strategic significance for ensuring national food security and increasing farmers'income. Because of the improper water control after harvesting, the proportion of mildew is over 5% and the loss is enormous. The centralized storage of grain after large-scale harvest is prone to mildew, which requires drying treatment to store and process. With the reduction of drying sites in rural areas, the use of dryers becomes an important option, which can effectively reduce the occurrence of mildew and ensure national food security.
4. Resistance to losses caused by natural disasters
Most of the main grain producing areas in China have seasonal climate, which is mild and humid and rainy. In the spring harvest season, affected by the plum rain, the summer harvest is plagued by the summer flood and typhoon; in the autumn harvest, the rain is often continuous, which causes the deterioration, germination and mildew of the grain, resulting in the poor harvest of the agricultural production. Developing grain drying function can improve the ability to resist natural disasters, solve grain mildew caused by climatic factors, delay drying after harvest, and ensure high yield and harvest of agriculture.
5. Raising the Level of Agricultural Mechanization
The level of Agricultural Mechanization in developed countries reached more than 90% before 2000, while the level of Agricultural Mechanization in China lagged far behind that in developed countries. As far as the current domestic dryer Market is concerned, the level of grain drying mechanization in China is less than 10%, which is the "short board" of the whole agricultural mechanization. The market gap is over 90%. Therefore, improving the market utilization rate of dryer is in line with the development road of agricultural modernization in China. According to the goal of agricultural and rural economic development, grain drying, as an important part of grain production operations, such as tillage, sowing, harvesting, drying, etc., is the last work link with large workload, short operation time and high operation requirements. It is of great significance to realize grain drying mechanization.
6. Saving Land Resources
Developing grain dryers can effectively protect cultivated land. With the continuous expansion of the scale of land transfer and the rapid popularization of combine harvesting machines, the harvesting efficiency has been greatly improved, the harvesting season has been shortened, and the original sunning habits have been gradually abandoned. If the grain dryer is not purchased, large grain-growing households will have to occupy precious arable land to build centralized drying farms and employ migrant workers to dry, thus causing waste of land resources and increasing labor costs.
7. Government support, grain dryer ushered in an opportunity period of development
China is a big agricultural country. The state supports, encourages and guides the development of modern agriculture. In recent years, the state finance has allocated special funds to subsidize farmers and large grain farmers to buy agricultural machinery products such as grain dryers. Some provinces, cities and counties (districts) have also put out special financial funds for agricultural machinery subsidies.
It is understood that since 2011, drying machines have been listed in the national agricultural machinery subsidy catalogue and given priority subsidies. In some places, such as Fujian, not only the 120,000 yuan subsidy standard required by the national subsidy catalogue is strictly implemented, but also the cumulative subsidy of 15% for grain dryers. Zhejiang, Guangxi, Henan and other provinces have added the same amount as the national subsidy. Subsidies, up to 60% of the cumulative amount of subsidies.
